QUESTION: Viewpoints Should we care whether a species goes extinct? • Yes, because all life is important and valuable. • Yes, because we are causing this wave of extinction, so we should fix it. • We should not, because it’s natural. • I don’t care; it really does not affect me.

QUESTION: Weighing the Issues Do you think humans are subject to limiting factors and, ultimately, a fixed carrying capacity? • Yes, although we have raised the carrying capacity, there are limits to the number of humans Earth can support. • Yes, but technology will keep raising the carrying capacity, so it’s not much of a problem. • No, humans are no longer constrained by environmental limits, due to our technology and ability to manipulate the environment. • I don’t care; it really does not affect me.
