– Warms earth
– Provides energy for plants to make
food for other organisms
– Powers winds
– Powers the hydrologic cycle – which
includes flowing water
– Provides energy: wind and moving
water can be turned into electricity
protect Biodiversity
Nota:
– Large variety of species
– Many ecosystems
• Deserts
• Forests
• Oceans
• Grasslands
– Species and systems renew soil
and purify air and water.
NOT disturb Chemical Cycling
Nota:
–Natural processes recycle nutrients
–Recycling is necessary because
there is a fixed supply of these
nutrients on earth
–Nutrients cycle from living
organisms to the nonliving
environment and back
–Chemical cycles are necessary to
sustain life

Ecological Footprint
Nota:
– The amount of biologically
productive land and water
needed to indefinitely supply the people in a given area with renewable resources
– Also includes the land and water
necessary to absorb and recycle wastes and pollution
per capita ecological footprint(area)
Nota:
Average ecological footprint of an
individual in a given area
Ecological deficit
Nota:
Total ecological footprint greater
than biological capacity for
resource renewal and absorption of wastes and pollution
