The 1992 United Nations Earth Summit defined biological diversity as "the variability among living organisms from all sources, including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part: this includes diversity within species, between species and of ecosystems". [15]
Almost no other ecosystem is as vulnerable to climate change as coral reefs. Updated 2022 estimates show that even at a global average increase of 1.5 °C (2.7 °F) over pre-industrial temperatures, only 0.2% of the world's coral reefs would still be able to withstand marine heatwaves , as opposed to 84% being able to do so now, with the figure ...
An example of an ecosystem service is pollination, here by a honey bee on avocado crop. Ecosystem services are the various benefits that humans derive from healthy ecosystems. These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood ...
Sustainability is regarded as a "normative concept".[5] [22] [23] [2] This means it is based on what people value or find desirable: "The quest for sustainability involves connecting what is known through scientific study to applications in pursuit of what people want for the future."
Some of the solutions he notes are the need for the development and facilitation of: ecological corridors, biodiversity protection networks, redlines for protecting ecosystems, market-based mechanisms for ecological compensation in addition to afforestation, greater crop rotation, recycling, waste reduction, stricter pollution standards, and ...
