Notice how the birds select orange or green bugs as you alter the levels of local pollution in this interactive activity from Kinetic City. This illustrates how environmental change affects the process of natural selection. A quickly changing environment can put an organism in a vulnerable position and present an evolutionary disadvantage. In this game, you control the amount of pollution produced by a nearby factory. Observe how the pollution affects the trees and the populations of different colored bugs that live in the trees.
