We tend to think extinctions only affect the animals which are gone. We forget that animals, vegetation and climate are linked. We also tend to forget that people act on their perceptions of their environment. If their environment changes slowly, they slowly adjust, and their perception of their environment does not change. But if their environment changes quickly, their perception of their environment as benign, also changes.

The materials at this site talk about the interconnectedness of ecosystems and the impact of extinctions on human perception.
