Synopsis: Our national bird is back in the lower 48 states after nearly disappearing in the 60's and 70's. Robert Mesta, a biologist with the U.S. Fish and Wildlife, explains what it takes to recover a species like the bald eagle, and demonstrates his use of math.

Critical Thinking:

If one is developing a plan for recovery of an endangered species which start with a population of, say, 200 animals, and projects a growth in population each year of “10 animals”, then the population, P, will be related to the number of years that pass, t, by this equation: P = 10t + 200
