Since you all seem to be enjoying mass extinction you must be thrilled to hear that we are experiencing the fastest mass-extinction ever right now. Thats right folks: lifeforms are disappearing faster right now than after the big asteroid hit earth.
The beginning of this extinction event (wich is called the holocene extinction event) seems to coincide with humans inventing agriculture.... one might suspect this is no coincedence...

First you're thinking of the Cretaceous extinction and second since the advention of agriculture humans have been breeding like bacteria.

No, i am not talking about the cretaceous extinction.
And humans might have been breeding like bacteria but other species have not:
When one turns a patch of ancient forest into farmland you reduce the number of species (not only animals...plants too) in that area by 95%. That constitutes mass extinction. In this case the humans do better because of the mass extinction but that does not mean it is not a mass extinction.

ZOMG. Nuke the volcanoes!!! They are pumping deadly carbon dioxide into the atmosphere and going to cause mass extinction.

Well, at least we'll leave future generations some pretty pictures of what once was, assuming we don't join the very long list of extinct species.

Another thing is the extensive fragmentation of the remaining areas that are still somewhat diverse biologically, like the Amazon basin. This is caused primarily by roadways. Everything has been subdivided by the very greedy H. Sapiens. This often damns the islands of greenery to a slow death. And then there are the many species (like nearly all the large mammals outside of our pet domestics) that have been so drastically reduced in number they are now functionally extinct because of genetic drift.

It's a pity, our priorities are all wrong. These other ancient strands of life are the true wealth of this world and we're destroying them all for nothing. Nothing lasts forever, but there's no reason to destroy the garden as we are.
