A Quote by Elizabeth Kolbert
We can't say that when x happens we get a mass extinction. To the extent we understand mass extinction, one has been caused by glaciation event, one has been caused by a massive climate change, and one has been caused by an asteroid. These events turn out to have no precedent.

In the history of the world, all five mass extinctions have been accompanied by massive climate change, so we are facing an incredibly serious threat. In fact, we are technically in the sixth mass extinction right now, and it is the first mass extinction being attributed to humans.
Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us.
The early Triassic was a period when the planet was recovering from the worst mass extinction it had ever known - that was the end Permian extinction, where climate change caused in part by mega-volcanic eruptions wiped out ninety-five percent of life on Earth. It took about ten or twenty million years for the planet's ecosystems to stabilize. During that time you saw a lot of weird, out-of-balance ecosystems where, for example, crocodile-like predators ripped the crap out of each other along the coasts.
Many scientists would argue that we are now in what is called Extinction, and it's caused by this perfect extinction storm: climate change, habitat loss, pollution, unsustainable exploitation of species and habitat resources, and of course, human population explosion. All of these factors work together and conspire to drive a species to extinction on our planet, every half an hour.
If you listen to the political discourse in America today, you would think that all our problems have been caused by the Mexicans of the Chinese or the Muslims. The reality is that we have caused our own problems. Whatever has happened has been caused by isolating ourselves or blaming others.
There is evidence that we are headed into what would be the planet's sixth mass extinction. It's hard to know for sure if you're in one because a mass extinction is an event where over 75 percent of the species on the planet die out over a - usually about a million-year period. The fastest it might happen is in hundreds of thousands of years.
The earth has continued to change, from rapid climatic changes that have caused the glaciers and the ice sheets to basically bulldoze the landscape and cause species compression in the tropics and cause mass species extinction - you know, all these huge changes. In terms of evolution, every species is doomed to eventual extinction. The natural world is constantly changing. So, to deal with "environmental problems," in quotes, totally misses the issue. That is not the way we want to define our problem if we're going to find our solution.
We are in the midst of the 6th largest extinction event in the history of the plant and the first caused by human action.
To be fair, if we are having a mass extinction, we're in the early stages of it. I think it's knowing facts like that which has made me less fearful about the future. Mass extinction is a long, complicated process that we are just now beginning to understand - and likewise, we are just beginning to understand how we might prevent one.
One area in which we can be certain mass immigration has an effect is housing. More than one third of all new housing demand in Britain is caused by immigration. And there is evidence that without the demand caused by mass immigration, house prices could be 10% lower over a 20-year period.
The Great Depression in the United States was caused - I won't say caused, was enormously intensified and made far worse than it would have been by bad monetary policy.
So i say, change the base! If you change the base, anybody will be as tall as anybody else! My belief is poverty is not caused by poor ppl. Poverty is caused by the system. Poverty is caused by the policies that we pursue.
With respect to phenomena like mass extinction, somebody might say why worry about it because in a geological perspective mass extinctions aren't so bad, they wipe out some things and then 10 million years down the road we get new and interesting objects.But I tell you mass extinctions are really awful for folks caught in the midst of them.
Climate change is real and it is caused to a significant extent by human activity.
Debt is not caused by spending, it is caused by buying things that you don't pay for. Or, it's caused by cutting revenues that you don't offset ... by cuts in spending.
There is good reason to believe that we have already entered the Sixth Extinction, a period of destruction of species on a massive scale, comparable to the Fifth Extinction 65 million years ago, when three-quarters of the species on earth were destroyed, apparently by a huge asteroid.
