Can We Do It?
People (we!) are becoming increasingly determined to lower
the risk that we and our children will experience major social
dislocation and environmental havoc as a result of rising
CO2 in the atmosphere
…and we are learning that there are many ways of
changing how we live, what we buy, and how we spend our
time, that will make a difference.
We are in the midst of a discontinuity:
What once seemed too hard has become what simply
must be done.
Precedents include abolishing child labor, addressing the
needs of the disabled, and mitigating air pollution.
