Function and Environment
The function and behaviour of this community will determine how the global ocean responds to broader environmental changes. The marine environment supplies many kinds of habitats that support marine life. Marine life is somehow depended on the saltwater that is present in the sea. A habitat is an environmental or ecological area inhabited by one or more living species.
Oceans and seas represent a public good for society and, a specific ecosystem - the marine ecosystem. Human activities such as pollutant discharge and fishing, influences the health and marine ecosystems, such as coral reefs. Conversely, human health depends upon the functions, products and services of the marine ecosystem. The study of oceans, seas and human health is in part a social and economic problem because it commits scarce resources to improve social well-being.
