In our current lab, "Population Biology," we are learning the principle of competitive exclusion: that no two species can occupy the same niche. Now, let's take this concept and expand it to the scale of the entire Earth. The human population recently reached 7 billion people. Do you feel we are nearing the Earth's carrying capacity for our species? Discuss any impacts the exponential growth of our species could have on other species and their habitat. Finally, describe what you could do to reverse the trend of competitive exclusion by humans so that we do not exhaust the limited resources of the Earth?
