I have known or at least met many environmental luminaries in the course of my career, and as one of them put it: I = P*S/T -- that is to say environmental impact is proportional to population and standard of living, but is inversely proportional to technology.
So the key to avoiding a dystopian future is to keep the rate of technological improvement greater than the rate of population growth. The way to do that is to invest in people. Societies who have lower infant mortality rates have lower birth rates; societies with better education are more innovative.
Will the future way we do things look radically different from today? Yes! Just as the way we do things today look radically different from the past. Change happens in both the environment and human society; it's inevitable. The question is whether it happens at a rate organisms and people can adapt to, and in particular whether we make a conscious decision to direct that change or have it forced upon us.
