68 percent in the past 50 years

Explanation:

That depends on the organization doing the computing, the species involved, the locations involved and what factors are the cause. We know that loss of habitat is a primary driver of biodiversity loss now. As our climate becomes warmer this will be accelerated in some areas and slowed in others. The five direct drivers of change in nature with the largest relative global impacts thus far are, in descending order: changes in land and sea use; direct exploitation of organisms; climate change pollution and invasive alien species.
