" Broadly conceived, however, ecology deals with the balance of nature. Inasmuch as nature includes man, the science basically deals with the harmonization of nature and man. This focus has explosive implications. The explosive implications of an ecological approach arise not only from the fact that ecology is intrinsically a critical science--in fact, critical on a scale that the most radical systems of political economy failed to attain--but it is also an integrative and reconstructive science.
