Question

What is a possible cause for a decrease in ecosystem productivity?

Answer 1

Humans have been impacting their environment since their great ancestors, but never has their impact been more harmful than in the 21st century.

Human actions have led to different changes on a global scale which often drive a decrease in ecosystem productivity. In specific, nutrient enrichment, exotic species invasions, and climate change are often known some of the most influential and omnipresent global ecosystem changes.

Unluckily, the mechanism by which global ecosystem changes affect ecosystem and biodiversity process. The combined effects of various changes are often not clear.
