Humans have been changing the natural cycle that reduces carbon from the earths atmosphere since we started burning fossil fuel. The climate change does not just intensify the earths climate is causing sea levels to rise and in some areas drought. These climate changes effect the plants and animals and eventually will be effecting us in more extreme ways then it has already has. We have sped up the natural extinction rate one thousand times. This means that although new species are evolving they are not evolving anywhere near as fast as the old ones are dying out. Friedman refers to the natural disaster, in his book Hot, Flat, and Crowded, as a flood and the solution is to build an ark. Humans need to find a way to build an ark in order to save ourselves from the destruction we have created.
