BBC Asteroid Impact Simulation End Of The World Predictions

A huge asteroid with a diameter of 500 Kilometer is going to impact on Earth! Destination: Pacific Ocean. The asteroid impact peels 10 kilometers crust off the surface of Earth. The resulting shockwave travels at hypersonic speed. The debris from the impact is blasted to the lower orbit of Earth, and they returns to destroy everything on the planet. The firestorm created by the asteroid impact encircles the Earth,

vaporizing everything in our world. Within 24 hours of asteroid impact, the entire Earth will be uninhabitable. The researchers have found that this scenario has happened 6 times in Earth's history.

Bananas Are Losing the War on Fungus

If you like bananas, you probably eat a lotof clones. That's because all bananas are clones orat least, Cavendish bananas are, and they're the cultivar, or variety, of banana that mostpeople eat. They're genetically identical to one another. And they're also all in danger of beingwiped out by a fungus. Cultivated bananas reproduce asexually, througha process known as parthenogenesis, which literally means “virgin birth.� Most plants have male and female flowerpartsand seeds, that are pollinated with

the help of things like the wind, or bees. Pollinationis the plant version of getting it on. There are ways to create new banana cultivarsif you pollinate them by hand, but it often fails, and even when it does work it's hardto know if your new banana will look good, taste good, and be easy to grow. So most bananas live a chaste life: if you'rea banana farmer, you get more banana plants by cutting off a piece of the stem of an existingbanana plant, and sticking it in the ground. That plant then matures, blooms with potentially more than three hundred bananas, and then dies. Because they're all the same, they're super vulnerable to disease. There's no chance that one banana plant will happen tohave a gene that makes it resistant

So if a parasite or a fungus can kill onebanana, it could potentially kill every banana of that type something that'shappened before. Back in 2013, we here at SciShow talked abouthow the Gros Michel banana, which was bigger, sweeter, and hardier than the Cavendish, wentvirtually extinct in the 1950s. The culprit was a highly infectious funguswe called Panama Disease. In the space of about ten years, Panama Disease reduced theGros Michel from the world's most popular fruit, to just another weird thing your grandparentstalk about that nobody else remembers. And the banana industry would have died withthe Gros Michel if it weren't for the last

minute switch to the Cavendish. While it wasn'tas big and it didn't taste the same as the Gros Michel, the Cavendish was immune to PanamaDisease. At least, the type of Panama Disease thatwas around at the time. In 2013, we also told you that a new strainof Panama Disease had emerged that could infect the Cavendish. But that it would probablybe fine! Infected fields were being quarantined, scientistswere working on developing a new kind of Cavendish that could resist the new disease, and hey!We had the lessons of history! We weren't gonna let what happened to the Gros Micheljust happen again, righté

So.here's an update on that story. According to a study published in Novemberin the journal PLOS Pathogens, this new strain of Panama Disease, known as “Tropical Race4� or just “TR4,� is spreading. It originated in northern Australia, and,the last time we talked about this, it was also in Southeast Asia and southern China.Since then, the researchers note, TR4 has reached the Middle East, through Jordan andLebanon, as well as Africa, through Mozambique. TR4 in Africa is especially concerning becausebananas in many parts of Africa, including Mozambique, are not just a tasty treat. They'rea staple crop, and a major component of national

food security. Even worse, it seems likely that TR4 couldalso infect other varieties of African banana, many of which are grown as subsistence cropsby rural families. What makes TR4 so dangerousé It's caused by a fungus that spreads throughsoil. If you didn't think dirt could carry disease: it can, and when it does, it'sbad. TR4 spreads through the dirt and infects plants via their root systems. Worse, it produces chlamydospores, or “restingspores,â€� which can lie dormant in the soil
