Respecting Planetary Boundaries - Life in the Anthropocene

PrintPrint

Before diving into specific sustainability issues, we'll get an overview of some of the key "planetary boundaries," as outlined by Carl Folke In Chapter 2 ofIs Sustainability Still Possible?As you'll see, we'll go over some of these in more detail in this lesson. One important term that Folke does not define, but is important to understand, is ecosystem services. The National Wildlife Federation defines an ecosystem service as "is any positive benefit that wildlife or ecosystems provide to people" (source: National Wildlife Federation). Examples include plants that convert carbon dioxide into oxygen, fisheries that naturally replenish themselves and feed humans, wetlands that filter toxins and mitigate storm impacts, soil organisms that foster plant growth, bees that pollinate food crops and other plants, and bats that control mosquito populations. We could cite innumerable examples, but without ecosystem services, life on earth would not be possible. Further, much of what we depend on for survival is offered for free by nature. Most ecosystem services are performed by the biosphere, which "includes all living organisms on earth, together with the dead organic matter produced by them." (Source: Encyclopedia of Earth).

How important are humans to the Anthropocene? Do they play a large role?

ANSWER:
Absolutely essential! The Anthropocene is defined by Carl Folke as "the age in which human actions are a powerful planetary force shaping the biosphere" (p. 19).
