Warm-up 4/7

• What is the main reason for the increase in the atmosphere of:– Carbon Dioxide?– Methane?

• How do the environmental pollutants H2SO4 (sulfuric acid) and HNO3 (nitric acid) enter the environment to cause acid rain?

HUMAN RESOURCE USE

• ecological (carbon) footprint: how much we impact the environment

• sustainability: the ability to meet human needs

FIELDS OF STUDY

• Conservation biology: identify, protect, and maintain natural areas at risk

• Restoration biology: rebuild the damaged ecosystems

• Use bioindicators (species especially sensitive to change) as early warning signals of environmental problems

CASE STUDY:Saving the whooping crane

Whooping crane: in 1870 about 20,000 migrated between the US and Canada, but 1937, only 15 remained because American settlers began to hunt the birds for feathers. By 1967 the US Fish and Wildlife Service began a captive breeding program which now produces about 30 cranes/year

PROTECTING ECOSYSTEMS

• Biodiversity hotspots: regions with the highest diversity that are most in danger

GOVERNMENT LAWS

• Debt-for-nature swap: portion of a developing nation foreign debt is forgiven in exchange for investment in environmental conservation.
