This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.
Sustainability is a social goal for people to co-exist on Earth over a long period of time. Definitions of this term are disputed and have varied with literature, context, and time. [2] [1] Sustainability usually has three dimensions (or pillars): environmental, economic, and social. [1] Many definitions emphasize the environmental dimension.
Excess channel erosion can result in rapid deepening or widening of the stream channel, all of which effect stream ecosystem functions and services. [6] They also provide essential servies to their aquatic life and associated organisms such as horses, who may depend on the stream for drinking water, or fish who depend on them for habitat.
Sustainability science focuses on issues relating to sustainability and sustainable development as core parts of its subject matter. [2] It is "defined by the problems it addresses rather than by the disciplines it employs" and "serves the need for advancing both knowledge and action by creating a dynamic bridge between the two".
Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and is the study of abundance, biomass, and distribution of organisms in the context of the environment.
Ecological literacy (also referred to as ecoliteracy) is the ability to understand the natural systems that make life on earth possible. To be ecoliterate means understanding the principles of organization of ecological communities (i.e. ecosystems) and using those principles for creating sustainable human communities.
