Non renewable: copper, oil, coal

Natural services = are functions of nature such as purification of air and water, which support life and human economies.

Vital natural service = nutrient cycling

Natural capital is support by solar capital

Solar energy: warm planet + support photosynthesis

2. Is to recognize that many human activities can degrade natural capital by using normally renewable sources faster than the nature can renew them.

3. Environmentalist scientist search for a problem such as degradation of natural capital and can only find scientific solutions for them. They way to force usually need political power or political coorperation. Usually will involve trade off, that will need agreement between 2 or more parties.
