| While there are many definitions of the word risk, the United States Environmental Protection Agency (USEPA) considers risk to be the chance of harmful effects to human health or to ecological systems resulting from exposure to an environmental stressor. A stressor is any physical, chemical, or biological entity that can induce an adverse response. Stressors may adversely affect specific natural resources or entire ecosystems, including plants and animals, as well as the environment with which they interact (USEPA, 1992).

What is risk? What is a stressor?
While there are many definitions of the word risk, EPA considers risk to be the chance of harmful effects to human health or to ecological systems resulting from exposure to an environmental stressor. A stressor is any physical, chemical, or biological entity that can induce an adverse response. Stressors may adversely affect specific natural resources or entire ecosystems, including plants and animals, as well as the environment with which they interact. |
Fascinating! Though the source seems to be named nothing has been marked as a citation. Indeed, the wording is not to be found in the referenced document, but - mostly identical - on the official web-page of the US EPA. Thus this fragment is not to be considered as a "pawn sacrifice" |
