It has long been hypothesized that extinction is a natural phenomenon. In fact, it is estimated that of all the species that ever lived, 99% are now extinct. Why then do we say that we are now experiencing an loss of biodiversity (extinction) crisis?

Why are we losing the species that currently exist and not giving the opportunity for new species to emerge.

Explanation:

Violent human exploitation of nature, pollution and climate change are causing the death of species, en masse, promoting a very large loss of biodiversity on the planet, without allowing new species to emerge. This is because new species need to evolve from old species, which are being killed these species are dying, there is no evolution. This lack of biological evolution promotes extinction and loss of diversity.
