A Quote by Richard Lewontin
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.

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.
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.
Of the four billion life forms which have existed on this planet, three billion, nine hundred and sixty million are now extinct. We don't know why. Some by wanton extinction, some through natural catastrophe, some destroyed by meteorites and asteroids. In the light of these mass extinctions it really does seem unreasonable to suppose that Homo sapiens should be exempt. Our species will have been one of the shortest-lived of all, a mere blink, you may say, in the eye of time.
The extinctions ongoing worldwide promise to be at least as great as the mass extinction that occurred at the end of the age of dinosaurs.
The Second Wave Society is industrial and based on mass production, mass distribution, mass consumption, mass education, mass media, mass recreation, mass entertainment, and weapons of mass destruction. You combine those things with standardization, centralization, concentration, and synchronization, and you wind up with a style of organization we call bureaucracy.
Mass extinctions may not threaten distant futures, but they are decidedly unpleasant for species caught up in the throes of their power.
If we return abruptly to a Miocene-like climate, it's reasonable to think that we would experience a lot of extinctions, and maybe even a mass extinction in the long term. Would the life on Earth be radically different? Of course we can't say for sure, but I think a lot of it would look familiar. Like a lot of people, I worry a lot about whether marine mammals would survive, especially whales. Ocean acidification is one of the major killers in climate change events, and that makes the ocean a very inhospitable place.
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.
Longevity is a huge factor in becoming separate from the mass of people that are just starting, or don't have any friends in the same realm, or don't really have the foundation. So it's good and bad, it's easy and it's hard. It's really what you make of it. Because if it's truly something that you really enjoy and obsess over, then waiting 10 years or waiting 30 years shouldn't be that big of a deal for you. As you get older and as you work harder, you see further down the road.
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.
As you know, this little grain of sand has mass. A very small mass, but mass nonetheless." And because this grain of sand has mass, it therefore exerts gravity. Again, too small to feel, but there." Now," Katherine said, "if we take trilions of these sand grains and let them attract one another to form... say, the moon, then their combined gravtiy is enough to move entire ocreans and drag the tides back and forth across our planet.
We tell our children they're trapped like rats on a doomed, bankrupt, gangster-haunted planet with dwindling resources, with nothing to look forward to but rising sea levels and imminent mass extinctions, then raise a disapproving eyebrow when, in response, they dress in black, cut themselves with razors, starve themselves, gorge themselves, or kill one another.
There is one living organism, called a tardigrade, that has survived the five great mass extinctions on Earth, and it can survive in vacuums in space and boiling hot water and freezing subzero temperatures.
If we don't cut carbon's money pipeline, we will pay for their gasoline with floods, droughts, fires, super storms, drowned cities, mass extinctions, wars, and collapsing civilizations.
Joblessness is a weapon of mass destruction. Poverty is a weapon of mass destruction. Hunger is a weapon of mass destruction. Poor health care is a weapon of mass destruction. Poor education is a weapon of mass destruction. Discrimination is a weapon of mass destruction. Let us abolish such weapons of mass destruction here at home.
We hear so much about weapons of mass destruction. But nine out of 10 war victims are killed by guns. It's the AK-47 that's a weapon of mass destruction.
