this is the million dollar question. And one that’s very hard to answer.

After centuries of debate, paleontologists are converging towards the conclusion that human overkill caused the massive extinction of large mammals in the late Pleistocene. This paper revisits the question of megafauna extinction by incorporating economic behavior into the debate. We allow for endogenous human population growth, and labor allocation decisions involving activities such as wildlife harvesting and (proto) agriculture. We find that the role of agriculture in deciding the fate of megafauna was small. In contrast, the presence of ordinary small animals that have been overlooked in previous non-economic extinction models is likely to have been much more important.

It is regarded as a tautology - the question is based on a false assumption.

Extinctions occur when the slow adaptation of organisms over time to their environment is not quick enough to help them respond to changing conditions.

This simply means the rate of species extinctions that would occur if we humans were not around.

** Between 1.4 and 1.8 million species have already been scientifically identified.




Unlike the mass extinction events of geological history, the current extinction challenge is one for which a single species - ours - appears to be almost wholly responsible.



This is often referred to as the 6th extinction crisis, after the

So without arguing about who’s right or wrong.

Or what the exact numbers are.

There can be little debate that there is, in fact, a very serious biodiversity crisis.
