In different parts of the world, species face different levels and types of threats.
The changes in ecosystems are harming many of the world's poorest people, who are less able to adjust to these changes and who are affected by even greater poverty, as they have limited access to substitutes or alternatives.
For example, poor farmers often cannot afford to use modern methods for services that were previously provided by biodiversity. Poor people have historically disproportionately lost access to biological products and ecosystem services as demand for those services has grown. The transfer in ownership of ecosystem resources often excludes local communities, and the products of their exploitation are not destined for the local market.

Species turnover caused by humans. Green areas have seen relatively little change; in red areas, the turnover has been 50% or more. Yellow areas are intermediate. From Ellis, E.C., E.C. Antill, and H. Kreft (2012) "All Is Not Loss: Plant Biodiversity In the Anthropocene."
