And they were already pretty bad before they could be custom-built. Scientists agree: Earth's temperatures are rising, there's more carbon dioxide in the atmosphere than at any point in human history, and we might just be beyond repairing the damage. Here's how it works.
Greenhouse gases like CO2 and methane absorb heat from the Sun and reflect it back into the atmosphere, warming the planet.
It's an observable fact that you can test for yourself at home. As humans release more and more of these gases into the air through industrialization and vehicles, the temperature continues to rise, changing the world in so, so many terrifying ways. Permanent effects have already been documented. In , scientists announced that a species of mammal had gone extinct due to climate change for the first time. The ice caps are melting, raising ocean levels to the point where cities like Venice are flooding , killing residents.
As weather patterns become more extreme, entire areas of the world could become uninhabitable. Economies could collapse. Ecosystems could collapse. And according to NASA , it'll take decades, maybe even centuries to stop even if we stop producing CO2 right this minute.
Maybe it's a little dour to pin all the potential end-of-days blame on human beings. After all, a deadly, highly contagious microscopic organism could sweep through mankind and we'd all die with a clean conscience. Historically, the only thing that's killed more humans than humans has been disease.
A few of the all-stars: the Black Death killed between one third and one half of everyone in Europe in the 14th century. The Spanish flu pandemic infected a third of the world and killed more than 50 million.
AIDS has led to the deaths of at least 25 million. The good news first: You'll notice that those numbers keep getting smaller with time. Our ability to confront and contain diseases gets better all the time. Now, the bad news. Diseases are getting better at fighting back. Overuse of antibiotics has made drug-resistant bacteria. Newer, more impressive strains of the flu come every year, and despite our remarkable advances, we still can't cure viral infections.
The best we can do is treat the symptoms and boost the body's natural defenses while we wait for our immune systems to do the heavy lifting. Combine all these facts with the knowledge that an infected person can travel more easily across the ocean than ever before, and you'll understand why doctors would just love for you to get your flu shot.
Like Agent Smith pointed out in The Matrix, humans have a lot in common with viruses. We consume and adapt every environment where we see fit to set up camp, trashing pretty much everything in our field of view.
In other words, maybe the real disease was us all along, and the friendships we made along the way. Man's ability to eat up resources is unparalleled in nature, and that can mean the end of delicately balanced ecosystems. It can be seen today in the way we suck the life out of rain forests , or in the rapid decline in worldwide insect populations due to destruction of their natural habitats.
Some scientists point to the collapse of ecosystems in the past as the beginning of a new epoch, dubbed the Anthropocene era , in which human actions such as deforestation and oil drilling caused more change more dramatically than any natural phenomenon in history. They posit that it could lead to worldwide biome instability. That said, we've seen it happen before, and it hasn't always been our fault.

Globally, it threw enough ash and debris into the air to, by some estimates, dim the sun for six years. They were already suffering from the cool, dry climate. Now they had to contend with multiple years of winter and an atmosphere full of noxious gases.
Some experts believe the entire population could have been whittled down to between 1, and 10, people. If Toba had as much of an impact as some people believe it did, from one year to the next, people were living in a different world. Analysis on the pollen before and after the Toba explosion , as taken from a core sample from the Bay of Bengal, show that tree cover died back and grassland grew in.
Whole ecosystems changed. The bottleneck resolves the paradox of the Out of Africa Replacement model: why do human populations look so different yet have such a recent African origin?
Or possibly not. The Toba idea is hotly contested. While some believe that it created a series of bottlenecks that turned humans into the weird and wild bunch we are today, others think it meant a few crappy years that left humanity essentially unchanged.
