AS BIOLOGY, F212: BIODIVERSITY:

GLOBAL DIVERSITY: DUE TO ACTION OF MAN-BIODIVERSITY IS DECREASING:

*Habitat destruction

*Over exploitation in "wild" habitats.

Pollution affects other "wild habitats"

*Etc

CONSEQUENCES: GENERALLY CONSIDERED NOT TO BE IDEAL AND THAT WE SHOULD BE MAKING A GREATER EFFORT TO CONSERVE NATURAL HABITATS AND SO MAINTAIN BIODIVERSITY.

BIODIVERSITY:

REASON TO MAINTAIN BIODIVERSITY:

*ECONOMIC

*ECOLOGICAL

*ETHICAL

*ASTHETIC

REASON TO MAINTAIN BIODIVERSITY:

ECONOMIC: SPECIES THAT MAY SOON INCOME EXTINCT MAY BE A FUTURE VALUE TO US.

ECOLOGICAL: IF SYSTEM ARE UNSTABLE AND THEY CHANGE RAPIDLY-POTENTIALLY CATASTROPHIC CONSEQUENCES.

ETHICAL: SHOULD WE BE ACTING A WAY THAT CAUSES OTHER SPECIES EXTINCTION?

AESTHETIC: MANY PEOPLE HAVE A PSYCHOLOGICAL BOOST FROM EXPERIENCING NATURAL ECOSYSTEM AND IT IS  PROVIDED A STIMULUS FOR ARTISTS.
