A cheap drug that can stop bleeding in recently injured accident patients could potentially save the lives of tens of thousands worldwide, a new study says.
Researchers studied the effects of tranexamic acid, or TXA, in more than 10,000 adult trauma patients in 40 countries who received the drug within 8 hours of being injured. They compared those patients' outcomes to more than 10,000 accident victims who got a placebo treatment. The study was published online Tuesday in the medical journal Lancet.
Doctors found that patients who got TXA had a 15 percent lower chance of dying from a hemorrhage than those who didn't get it. They also had a 10 percent lower chance of dying from any other cause, including organ failure and a head injury, versus patients who didn't receive TXA. The study was paid for by the British government.
The drug is commonly used in wealthy countries during elective surgeries to stop bleeding, but isn't prescribed for accident victims.
TXA is off-patent and manufactured generically by many companies. It costs about 3 pounds ($4.50) per gram, and a typical dose is two grams. It is usually given via an injection and would be relatively easy to introduce, even in poor countries, experts said.
''This is one of the cheapest ways ever to save a life,'' said Ian Roberts, a professor of epidemiology at the London School of Hygiene and Tropical Medicine and one of the study's main investigators.
Previous tests of the drug regarded its use in elective surgeries, such as heart operations, but this was the first study to test the drug on accident victims.
Doctors were worried it might increase side effects such as blood clots in the heart and lungs, strokes, or heart attacks. There was no evidence of that in the Lancet study, though the authors said it was possible they might have missed some of these incidents.
For people between 5 and 45, accidents are the second leading cause of death worldwide after AIDS, and about 600,000 injured patients bleed to death every year. Nearly 6 million people die of injuries every year, more than AIDS, malaria and tuberculosis combined.
Roberts and colleagues estimated that if TXA were readily available, between 70,000 and 100,000 lives a year could be saved. Though the drug wasn't tested in children, he said it would almost certainly work in them as well.
Etienne Krug, director of violence and injury prevention and disability at the World Health Organization, said the drug would likely have the biggest impact in developing countries such as China and India, where 90 percent of injury-related deaths occur.
''People often have a fatalistic attitude about accidents and think nothing can be done to save people,'' he said. ''But this study shows that isn't true.''
Experts said rolling out TXA could save as many lives as other measures such as making seatbelts compulsory or strengthening drunk-driving laws.
The drug also could save thousands of people in the West.
''This is not just something for developing countries,'' said Dr. Karim Brohi, who works at one of London's busiest emergency rooms at Barts and the London School of Medicine and University of London-Queen Mary. ''We could probably use tranexamic acid on a daily basis.''
Last week, Roberts and colleagues submitted an application to WHO to include TXA on its List of Essential Medicines, which is used by many developing countries as a shopping list for drugs. Once drugs are on WHO's list, other U.N. agencies such as UNICEF often buy the drug for poor countries.
''In many developing countries, emergency departments are like war zones, even when there's no war,'' Roberts said. ''If (TXA) is available, a lot of those deaths could be avoided.''

Boost Your Online Business With Effective Business Blogging
When you enter into an online business, there is not doubt that you have to set aside a budget for advertising. However, not all forms of advertising are necessarily going to cost you a boat load of money just to get started. If you are seeking a new and improved method of advertising your online business, looking into effective business blogging can bring you the revenue that you would normally spend for advertising.
Statistically speaking, business blogging is the fastest growing form of online advertising, and the key is that there aren’t any catchy words to toss out, no copy and paste data entry to deal with, and no fees for competing with the pay-per-click advertisers that make thousands off of your internet marketing efforts. Effective business blogging is as simple as you want to make it and often more effective than pay-per-click experiences. There are more effective business blogging campaigns out there (80,000 blogs that show up on the internet every twenty four hours and well over 50 blog enthusiasts) which means that you have a wide audience to cast a huge and authentic net.
Effective business blogging allows you the perfect opportunity to open up a dialog with your potential clients or business associates before they invest in your word. Developing trust and authentic relationships can take a little time, but once the trust had been established your business is likely to grow faster than you ever thought possible. Effective business blogging provides a forum for all parties to provide feedback and commentary to help you develop better business skills and offer the services or enhancements that will effectively help your business take off.
Effective business blogging also helps you develop a strong community of supporters. Bloggers are loyal people who tend to run toward their favorites and away from their least favorites, a simple human element that is alive and well in the blogging community. When you treat the blogging world with respect, the bloggers in return recommend your site, product, or services to others.
Effective business blogging means dropping the advertising campaigns. Blogs are the perfect backdrop to talk to potential clients or associates without selling them on your business. Give readers something of value to hold in their brains or their hearts and you will be fully aware of just how much buying power rests in the blogging community.
By combining the power of RRS feeds, keyword phrases, and effective business blogging all on one blog site, your business is placed in the most effective position to reap the benefits and financial rewards associated with the most effective business blogging. Test your blogs in several different venues and make sure that you educate yourself on the basics of effective business blogging. Unfortunately, one poor post can have a residual effect, but one good post is also likely to have a residual effect. Learn all that you can about the rules, as well as the unwritten rules, of effective business blogging in order to play on the same field as everyone else. This simple step can save you thousands in one costly error.
When you are ready to set up your own blog, follow the basic guidelines below in order to promote your business and receive the ultimate benefits of effective business blogging.
Start with interesting topics that allow you to integrate you blog design into your company. This isn’t that hard, just a little forethought (perhaps a template) and some creative help on the side if you choose can bring your new blog into the limelight faster. Always make sure you cover your legal ramifications and post disclaimers that refute your liability for content and the opinions of others and any harm that could come of inappropriate posts. This is a simple step that all effective business blogging should have just to make sure they don’t end up with a silly little legal hang up that can drive you under.
Always set the standard by posting your own terms of use and policies. You are permitted to set up basic limitations and offer content control. You also reserve the right to remove any offensive material.
Use your business blog as a forum, and don’t work too hard on the sales end of effective business blogging. Selling to your readers is an immediate turn off, as we are all bombarded with commercialism way too fast and hard these days.
Always update your business blog on a regular basis and research your new and improved content in order to keep your business blog interesting for your audience. Avoid bland talk about products and the superiority of your business.
If you have people who work for you, encourage or even mandate that all company employees use business blogging to enhance their own sector. For large companies, this can improve business morale and function and for small companies this can effectively help the business grow. Blog the first fifteen to twenty five posts prior to sending your effective business blog out into the marketing end. This makes it look more complete and offers readers a chance to integrate their thoughts on more than just one or two posts.
An effective business blog is not a set and leave it type of element. In fact, effective business blogging requires regular updates and attention in order to make it function well. Never believe that your blog will take care of itself or you will lose the ground you have already covered.
In the mean time, Good Luck on your journey to success…

Group G Betting Preview World Cup 2010
Aah, the so called group of death - and no, we're not referring to North Korea's human rights record. Pundits have been licking their lips at the prospect of this quartet, which pits together the World Cup specialists, a talented if slightly flawed European outfit, a powerful African nation and an unknown quantity from Asia.
Brazil are clearly the favourites to win the group and you'll find some value in them at 1.50 to finish first in Group G. Dunga has moulded a strong team, who may not be as pretty on the eye as previous Selecao teams, but are very effective and boast an excellent defence. A win in their first game over North Korea should set them up nicely to progress here.
Portugal are only two places (3rd) behind Brazil (1st) in the FIFA rankings. With an abundance of attacking talent they could quite conceivably go all the way. However, they are a frustrating team with their players seemingly unable to find their best form at international level. Cristiano Ronaldo failed to find the net in qualification and there are question-marks over coach Carlos Queiroz. This is his opportunity to prove he shouldn't have remained as Alex Ferguson's assistant at Manchester United.
Ivory Coast, or Cote d'Ivoire if you'll pardon my French, were tipped by some to go all the way in the World Cup. We heard the same thing about les Elephants in the African Cup of Nations and they didn't pull up any trees there. New coach Sven-Goran Eriksson isn't known for his motivational qualities and is more than capable of leading them to a first round exit. Didier Drogba breaking his arm didn't do the Swede any favours either. They have the talent but do the Africans have the mentality? Hmmm.
North Korea looked defensively strong in qualifying as they conceded just five goals in 14 games. Keeping Kaka, Ronaldo and Drogba out will be an altogether different task from bolting the door against Saudi Arabia, for instance. As has been well documented, the North Koreans have been training in a public gym in Johannesburg which can't be ideal. In Jong Tae-Se they have a potential global superstar and it would be foolish to suggest they are in South Africa just to make up the numbers. Korea DPR will compete hard but are likely to be found wanting on talent.
Betting Potential
There is value to be found on the dual forecast as we all expect Brazil to progress. Dunga's side are 2.80 to go through with Portugal and 3.25 with the Ivory Coast with the Selecao topping the group. If you have little faith in North Korea consider the handicap market where you will get some good odds like Brazil at -2.5 at 2.21.

Misi Penabrakan Bulan
Misi penabrakan kawah bulan NASA yang dilakukan oleh Lunar Crater Observation and Sensing Satellite (LCROSS) telah membuat lubang dengan lebar 92 kaki.
"Ada indikasi yang jelas segumpal uap dan puing-puing," kata penyelidik utama misi LCROSS, Anthony Colaprete, dalam sebuah pernyataan. "Dari berbagai model prediksi yang dibuat, kami mendapatkan hasil yang kurang baik namun ini dapat menjadi petunjuk untuk melihat dampak dari sifat material Centaur."
Dalam dua benturan beruntun yang dilakukan LCROSS utama, kemudian diikuti pesawat ruang angkasa pendukung membentur kawah Cabeus bulan pada 9 Oktober, dalam kecepatan sekitar 6.000 mil per jam. Ini merupakan upaya NASA dalam menggali air yang terperangkap dalam debu bulan untuk dianalisa.
Tim terus meneliti zat kimiawi yang didapatkan dalam misi tersebut untuk mencari petunjuk adanya air. Ilmuwan mengharapkan jika air yang ditemukan dapat digunakan unutuk membantu para astronot masa depan yang berbasis di bulan. Ia juga menambahkan bahwa pertemuan sains pada bulan Desember kemungkinan akan menampilkan temuan mereka.
Belanda Dan German Di GegerKan Ledakan Meteor
Fotografer amatir Robert Mikaelyan mendapatkan gambar langka saat bola api besar meledak di angkasa. Peristiwa ini terjadi sesaat setelah ia keluar untuk mengambil foto pabrik gula tua Belanda.
Mikaelyan berhasil mendapatkan gambar beberapa tembakan dari bola api yang berayun rendah di atas kota Groningen bagian utara, sebelum akhirnya mulai pecah menjadi potongan-potongan yang lebih kecil.
"Aku tiba-tiba melihat cahaya di langit datang dengan cepat ... dan bergegas untuk mendapatkan gambar," kata Mikaelyan.
Beberapa detik setelah bola api telah terlihat, saksi mendengar ledakan diikuti oleh gemuruh rendah yang mengguncang jendela.
Objek tersebut kemungkinan besar adalah batu luar angkasa yang hancur setelah menghantam atmosfer bumi, kata para ahli yang juga berspekulasi bahwa potongan-potongan meteor mungkin mendarat di Laut Utara.
"Ini adalah peristiwa besar," kata Theo Jurriens, dari Institut Astronomi Kapteyn di University of Groningen.
Saat ini bumi terus-menerus dibombardir oleh puing-puing yang lebih kecil dari komet, asteroid, bahkan planet berbatu lainnya di tata surya.
Tapi bola api dengan ukuran seperti itu dan cahaya seterang ini mungkin hanya terlihat setiap 20 sampai 25 tahun, Jurriens memperkirakan.
Internet Bisa Sebabkan Sakit Jiwa
Penggunaan internet secara obsesif dapat menciptakan epidemi kesehatan mental dan sekitar 10% remaja berisiko terkena akibatnya, kata akademisi di Sydney memperingatkan.
Dunia penelitian telah mendokumentasikan tingkat bahaya dari adiksi internet di mana penggunaan komputer berlebihan dan mengganggu kehidupan sehari-hari, kata Lawrence Lam ahli epidemiologi perilaku di University of Sydney dan Children's Hospital di Westmead.
Di Yunani dan Amerika Serikat, studi menemukan 8 persen remaja dapat digolongkan sebagai pecandu komputer. Di China, di mana Dr Lam membantu penelitian yang dilakukan baru-baru ini, tingkat adiktif dari penggunaan komputer mencapai 14 persen.
Dr Lam mengatakan para peneliti belum sepakat mengenai apakah masalah ini akan diberi label sebagai kecanduan atau masalah kesehatan mental. Tetapi kondisi ini diharapkan dapat masuk ke buku Diagnostic and Statistical Manual of Mental Disorders edisi berikutnya yang digunakan oleh para profesional ahli kesehatan mental sebagai referensi utama.
Dia mengatakan orang-orang yang memainkan game online seperti World of Warcraft, sangat rentan terhadap kondisi yang didefinisikan sebagai "tak terkendali dan merusak penggunaan internet".
Dr Lam mengatakan anak laki-laki 50 persen lebih rentan daripada anak perempuan. Dia menyarankan orangtua untuk mengamati perubahan pada anak-anak, serta seberapa sering atau seberapa lama mereka online.

German Di GegerKan UFO
Aparat di Bremen, Hamburg, North Rhine-Westphalia dan Lower Saxony mendapatkan pengaduan dari warga yang khawatir tentang adanya "bola terbakar" dan "obyek terang di langit."
"Tiba-tiba ada bola cahaya di langit, dan terlihat lebih besar daripada bintang jatuh," kata Christian Pokropp (30).
Pria itu sedang jogging disepanjang sungai Elbe di Hamburg dan melihat "bola bercahaya" pada pukul 18:50.
"Orang-orang yang berada di sepanjang sungai, seperti tersihir menyaksikan pemandangan itu," kata Pokropp.
"Ini berlangsung sekitar enam detik, sebelum benda pecah menjadi empat bagian dan tampak seperti bola api kecil yang mulai redup. Walau sebentar, Anda bisa melihat garis-garis asap di langit."
Setelah beberapa pengaduan, departemen kepolisian memberitahukan otoritas aviasi di Bremen dan mengirimkan sebuah mobil patroli. Seorang juru bicara Departemen Kepolisian Bremen, Dirk Siemering, mengatakan, "Ini masih misterius."
Menurut Siemering, penelepon mengatakan melihat “bola” hancur berantakan dan jatuh ke tanah." Saksi mata lainnya melaporkan ledakan besar.
Setelah panggilan darurat di Neubrandenburg, polisi menguasai wilayah di sekitar Waren. "Kami memeriksa untuk melihat apakah ada tangki gas atau gas alam yang terbakar di suatu tempat," tutur jubir lain.
Seorang pengemudi melaporkan melihat "sesuatu yang terbakar dan berwarna hijau sekitar 10 kilometer jauhnya" saat berkendara di Bundesstrasse kilometer 192 antara Neubrandenburg dan Waren.
Menurut "Express" salah satu saksi membuat posting di forum Internet: "Malam ini saya melihat bola aneh bercahaya hijau dengan ekor yang berapi-api jatuh melalui langit di Dortmund antara stasiun kereta dan U-Turm.
"Entah bagaimana benda itu larut dalam langit. Pertama-tama saya pikir itu adalah roket, namun lintasannya terlalu aneh."
Penggemar astronomi, Werner Walter, yang menjalankan sebuah jaringan penelitian UFO disebut CENAP di Mannheim, mendapat laporkan testimonial dari saksi-saksi di Brandenburg, Mecklenburg-Vorpommern, Hamburg dan North Rhine-Westphalia sampai larut malam.
Menurut laporan Walter, saksi mata menggambarkan sebuah " bola putih kehijauan yang bersinar" dengan ekor yang berlari ke bawah. Walter mengasumsikan bahwa fenomena yang terjadi adalah bintang yang jatuh ke atmosfir bumi dan hancur.

Vatikan Pamerkan Bola Surgawi
Pada pengarahan sebelum memulai pameran, Monsignor Gianfranco Ravasi, pejabat kebudayaan tertinggi Vatikan menolak untuk meninjau kembali keputusan gereja abad ke-17 yang mengutuk Galileo atas penemuannya yang menyatakan bahwa bumi berputar mengelilingi matahari.
Ajaran gereja pada saat itu menempatkan bumi sebagai pusat alam semesta. Namun sebaliknya, Ravasi mengatakan bahwa, perlu keberanian untuk mengakui kesalahan. "Saya tetap percaya bahwa melihat ke masa depan lebih penting."
Saat itu gereja mengutuk teori Galileo dengan alasan berbahaya bagi iman. Mereka mencoba membuatnya sebagai ketetapan aturan pada tahun 1633 dan memaksa Galileo untuk mengakui kesalahan. Ia pun dijatuhi hukuman penjara seumur hidup, namun kemudian berubah menjadi tahanan rumah.
Peraturan tersebut memperkuat tuduhan bahwa gereja bermusuhan dengan ilmu pengetahuan, sebuah reputasi yang telah coba diubah Vatikan sejak saat itu.
Pada tahun 1992, Paus Johanes Paulus II menyatakan bahwa putusan terhadap Galileo adalah sebuah kesalahan yang dihasilkan dari "kesalahpahaman tragis."
Pameran tersebut dan inisiatif Vatikan lainnya dimaksudkan untuk menandai peringatan 400 tahun teleskop Galileo dan penetapan Tahun Internasional Astronomi oleh PBB, merupakan bagian dari upaya Vatikan dalam rehabilitasi yang berkelanjutan.

Satelit Indonesia Nyasar
Satelit Palapa D yang dimiliki perusahaan komunikasi satelit Indosat itu diluncurkan dengan roket Long March 3B buatan China dari situs peluncuran roket Xichang di provinsi Sichuan, wilayah barat daya China.
"Roket pertama dan kedua secara normal berhasil masuk luar angkasa, namun roket ketiga gagal selama pembakarannya," lapor kantor berita China Xinhua.
Bulan Maret lalu, China menjanjikan akan mengganti semua biaya Satelit Komunikasi Nigeria seharga US$ 340 juta NIGCOMSAT-1 setelah satelit itu gagal melanjutkan misinya setelah 18 bulan berada di orbit. Satelit ini juga diluncurkan dari Xichang, pada 2007.
China dengan cepat memperluas kemampuan antariksanya dan berencana mendaratkan sebuah wahana di bulan pada 2012. Kemampuan China dalam meluncurkan satelit komunikasi asing bisa menyokong pengembangan kehadiran antariksanya sendiri.
Negeri ini berencana meluncurkan dua atau tiga laboratium udara antara 2010 dan 2015, sebelum ditumpangkan pada satu stasiun antariksa pada 2020, demikian Harian China, Selasa, mengutip Gu Yidong, mantan kepala program antariksas berawak China.
China sedang membangun sebuah pusat peluncuran baru di pulau selatam Hainan, yang posisinya lebih baik ketimbang Xichang ataupum pusat peluncuran China lainnya di provinsi Gansu.
Perusahaan Prancis ThalesAlenia Space, yang membuat satelit Palapa D, mengatakan bahwa satelit itu telah ditarik, sementara para pakar tengah menyelidiki kesalahannya, lapor Xinhua.
PT Indosat Tbk (Indosat) menyatakan peluncuran satelit Palapa-D di Xichang China berhasil dengan sukses.
”Kami bersyukur kepada Tuhan YME atas berhasilnya peluncuran satelit Palapa-D dalam kondisi cuaca yang sangat mendukung sehingga proses peluncuran berjalan dengan lancar,” kata Harry Sasongko, President Director & CEO Indosat di Xichang, China.

Satelit Korsel Nyasar ke Mana?
"Kami tak dapat menemukan satelit tersebut di orbitnya, tempat satelit itu mestinya berada," kata Menteri Ilmu Pengetahuan Ahn Byung-man dalam suatu taklimat. Ia menyebut hal itu "gagal sebagian".
Namun, pemerintah menyatakan Seoul belum mengidentifikasi penyebab pasti peristiwa itu. Seoul masih mengamati satelit tersebut yang menyala sebagaimana rencana, tapi 26 kilometer lebih tinggi dari posisi sasarannya.
"Kami sekarang melakukan analisis guna memeriksa seberapa jauh satelit itu menyimpang dari orbit sasarannya," kata Lee Joo-jin, pemimpin pusat ilmu pengetahuan yang bertanggung jawab atas peluncuran tersebut.
Ditambahkannya, satelit itu tak memiliki peluncur sendiri, yang berarti satelit tersebut tak dapat ditempat
kan di orbit lagi.
Namun, Lee tak bersedia mengatakan apakah kontak dapat dilakukan dengan satelit itu, dan juga tak mengatakan bahwa satelit tersebut telah "hilang".
Kendaraan-1 Peluncuran Antariksa Korea (KSLV-1), yang membawa satelit itu, diluncurkan pukul 17:00 WIB dan belakangan berhasil melakukan pemisahan tahap-1 dan tahap-2.
Meskipun pemisahan tahap-dua mengandung risiko, media setempat melaporkan bahwa Korea Selatan telah berhasil dalam peluncuran roket antariksa tahap pertama. Namun satu jam kemudian saat satelit tersebut tak ditemukan di orbit yang direncanakan.
Peluncuran roket tersebut mulanya dijadwalkan diselenggarakan pada 30 Juli, tapi harus ditunda dua kali sampai 19 Agustus akibat masalah teknis.
Namun jadwal peluncuran 19 Agustus kembali ditunda tujuh menit dan 56 detik sebelum mesinnya dihidupkan akibat gangguan di tangki tekanan tinggi, yang dapat mempengaruhi semua katup pada roket tahap pertama.

Virus Asing Kalah Bahaya Dari Virus Lokal
Virus buatan Indonesia diyakini lebih berbahaya dari produksi asing, karena virus lokal tersebut bisa menghilangkan data file.
"Sementara, virus asing tidak sampai menghilangkan file penting penggunanya. Produsen virus tersebut hanya ingin menunjukkan kelemahan windows yang ada saat ini," kata Technical Security Consultant, ESET Indonesia, perusahaan di bidang keamanan digital, Yudhi Kukuh, saat dihubungi ANTARA, di Surabaya, Minggu.
Namun, jelas dia, dari sejumlah virus yang menyebar di seluruh jaringan komputer di dunia, virus asal Indonesia hanya menyumbang 0,1 persen.
"Meski penguasaannya terbilang minim secara internasional, pengguna komputer perlu menyadari pentingnya antivirus untuk melindungi data," ujarnya.
Sampai saat ini, kata dia, variasi virus di dunia sangat beragam. Akan tetapi, yang kini menjadi tren dan berbahaya adalah virus "configure". Virus ini sifatnya bisa menggandakan diri, sehingga kini variannya bisa mencapai turunan ke-30 ("configure" varian AQ).
"Mayoritas, selama ini yang menyerang komputer di antaranya `configure generic`, `configure` varian A, dan `configure` varian AA," katanya.
Sementara, ia mencontohkan, ragam virus lokal yang juga membahayakan data pengguna komputer seperti babon, aksika, "coolface & coolface MP3 player", W32/Kill AV, pendekar "blank", pacaran, "blue fantassy", "Windx-Matrox".
"Selain itu, ada juga virus amburadul, `FD Shield`, Purwo C, dan Nadia Saphira," katanya mengungkapkan.
Terkait pengguna antivirus ESET, "Marketing Communications" ESET Indonesia, Chrissie Maryanto, menyatakan, sampai saat ini pasar terbesar sebanyak 60 persen berada di Jakarta, 30 persen di Surabaya, dan 10 persennya menyebar di kota lain.
"Dari jumlah tersebut, segmentasi pasar kami terdiri dari 80 persen kalangan korporasi dan 20 persen pelaku usaha ritel," katanya.
Khusus di Surabaya, ia siap menembus pasar ritel di kota tersebut. Salah satunya dengan menjalin kerja sama dengan peritel yang bergerak di bidang teknologi informasi (TI). Sementara itu, sejak Agustus ini ia telah memiliki `reseller` di Jakarta, Bandung, Yogyakarta, Surabaya, Malang, Jember, Bali, Balikpapan, dan Papua.
"Mengenai upaya menarik konsumen, kami memberikan promo Merdeka Dari Virus dengan harga promosi untuk `Home Edition` seperti ESET Antivirus NOD32 yang kini menjadi 24,99 dolar Amerika Serikat (AS), dari harga normal 39,99 dolar AS," katanya.

Bendungan Hoover pecah? Bagaimana Akibatnya
Bendungan Hoover merupakan salah satu keajaiban dunia modern yang tidak dapat diuraikan dengan kata-kata. Jika kamu berdiri di dekatnya, ukurannya luar biasa. Ketinggiannya 700 kaki (bayangkan bangunan bertingkat 70), dan puncak bendungan lebih dari 1.200 kaki. Dasar bendungan luar biasa tebal, yaitu 660 kaki dan tebal puncak 45 kaki. Kedalaman air di sisi danau sekitar lebih dari 500 kaki dan menampung 10 triliun galon air yang cukup untuk menggenangi kota Connecticut sedalam 10 kaki.
Apabila bendungan Hoover jabol, sulit membayangkannya kekuatan apa yang mampu menjebol dilihat dari ketebalan dindinnya. Tidak ada bom biasa yang mampu menjebol sebuah bendungan sebesar itu.sulit membayangkan kekuatan tersebut, bahkan bom nuklir sekalipun. Kecuali, bom nuklir yang berkukatan tinggi meledak di dalam bendungan. Akan tetapi, katakanlah sebuah gempa bumi yang luar biasa dahsyatnya, sebuah asteroid, atau bencana alam lainnya merupakan contaoh bagaimana meruntuhkan bendungan Hoover dalam sekejap. Apabila bendungan Hoover betul-betul jabol, apa yang mungkin akan terjadi? Peristiwa pertama yang akan terjadi adalah 10 triliun galon air akan mengalir sangat deras seperti muntahan air danau dan aliran sungai seperti saat terjadi badai tsunami yang dahsyat.
Bendungan Hoover terletak di wilayah gurun. Penduduk yang tinggal di bawahnya tidak padat, tetapi masih cukup banyak. Kota Danau Havasu, dengan populasi penduduk 40.000 jiwa, adalah kota terbesar di sepanjang sungai. Kota Bullhead dengan populasi 30.000 jiwa berada di dekat bendungan, sedangkan kota Needless, California; Blythe, California; dan Laughlin, Nevada masing-masing berpenduduk sekitar 10.000 jiwa.
Air yang akan menimbulkan kerusakan besar adalah air danau yang berada di bawah bendungan Hoover. Danau lain di bawah bendunga Hoover adalah danau besar yang diseebut Lake Mohave, dengan Bendungan Davisnya, dan dibawahnya terdapat Danau Havasu dengan Bendungan Parker. Keduanya adalah danau dan bendungan yang lebih kecil. Sebagai contoh danau Havasu hanya menampung 200 miliar galon air.
Ketika air yang dimuntahkan bendungan Hoover mengalir dengan deras melalui kedua danau itu, air akan menghancurkan kedua danau dan kedua bendungan itu. Pada saat itu muncul akibat baru yang menimpa penduduk kerena danau-danau ini merupakan kebutuhan hidup sebagian besar orang. Air bendungan itu digunakan untuk energi hydroelectric (listrik tenaga air), irigasi, dan air minum untuk kota-kota seperti Los Angles, La Vegas, Phoenix, dan San Diego.
Bendungan Hoover menghasilkan kekuatan listrik sebesar (perkiraan kasar) 2.000 megawatt. Bendungan Davis dan Parker menghasilkan lebih sedikit tenaga listrik, tetapi keduanya jika digabungkan menghasilkan listrik 3.000 megawatt. Listrik sebesar itu memenuhi 0,5% kebutuhan listrik total penduduk Amerika Serikat. Apabila kamu mengurangi pasokan listriknya, khususnya di wilayah kota (dekat Los Angles dan Las Vegas), tentu saja akan menimbulkan masalah sangat besar.
Perusahaan penyidai air irigasi juga akan terpengaruh. Sebagian besar para petani di perbukitan Imperial mendapatkan air dari Sungai Colorado. Apabila bendungan Hoover runtuh, system irigasinya akan terhenti. Perbukitan Imperial ini mengandalkan irigasi dari Sungai Colorado karena perbukitan Imperial dahulu adalah gurun yang tandus. Sekarang ini, di perbukitan Imperial terdapat jutaan hektar tanah pertanian dan mampu memproduksi labih dari satu miliar dolar dari buah-buahan dan sayur-sayuran setiap tahun.
Akibat lain jika bendungan jebol, adalah kehilangan sumber air minum. Misalnya, kota Las Vegas memenuhi 85% air minum dari Danau Mead (sebuah danau di hulu bandungan Hoover). Dengan hilangnya air dan hilangnya listrik, Las Vegas akan menjadi tidak berpenghuni, membuat 1,5 juta penduduk menjadi pengangguran, dan lebih dari 120.000 kamar hotel akan kosong, demikian juga rumah judi di kota ini akan terhenti. Oleh karena itu, pertanyaan di atas bukankah seperti sebuah iklan yang luar biasa! Berapa banyak yang bergantungpada satu bendungan itu.
