#41 Compare two patterns of population growth



There are two patterns of population growth. The Figure LEFT shows a logistic growth of a sheep population; by contrast, the Figure RIGHT shows a sharply increasing and decreasing growth. Please work in group of 2 or 3 and use the comment function to answer:

Question 1: Why do you think the population in the Right figure grew fast and crashed, unlike the sheep in the Left figure?

Question 2: Humanity's ecological footprint is about 25% larger than the earth's ecological capacity and is growing rapidly. If this keep up, is the curve for future human population growth more like to resemble Figure Left or Figure Right? Explain.
