CPES Ch 7 Test Review Saving Species & Ecosystem Services

Estimates of future extinction rates might be underestimated. What is the reason they might be UNDERestimated?

• Human population growth & environmental degradation

• They are not UNDER estimated, they are OVER estimated

• As humans, we need NOT worry about other organisms going extinct

• There is plenty of room for every organism
