The next major events in ecology were the development of the concept of biosphere and the appéarance of terms "biological diversity"—or now more commonly biodiversity—in the 1980s.  These terms were developed during the Earth Summit in Rio de Janeiro in 1992, where the concept of the biosphere was recognized by the major international organizations, and risks associated with reductions in biodiversity were publicly acknowledged.

Then, in 1997, the dangers the biosphere was facing were recognized from an international point of view at the Kyoto conference.  In particular, this conference highlighted the incréasing dangers of the greenhouse effect—related to the incréasing concentration of greenhouse gases in the atmosphere, léading to global changes in climate. In Kyoto, most of the world's nations recognized the importance of looking at ecology from a global point of view, on a worldwide scale, and to take into account the impact of humans on the éarth's environment.
