continued presentations:
stop global warming?
need to be more careful with the gases we are allowing into the ari and save energy
individual level: use eco friendly products or renewable evergy sources
conserve the resources that are slowly disappearing. oil, coal, etc
an everyday thing you can do is clean a dirty filter to save 50 pounds of co2 a year (furnace)
next is abby brittany and melissa doing polution, fossil fuels, and alternative energy options
dependance on fossil fuels:
oil coal and natural gas are non renewable
when they start ndwindling, there will be war, starbation, because we are dependent on cheap ready oil-deadly addiction
mining coal is dangerous and difficult
fossil fuels form from the organic remains of prehistoric plants and animals-it take hundreds of years to reproduce
burn fuel>heat water to make steam>steam turns turbines> turbines turn generators>electrical power
Polution:
referred to human activities that affect the world around us.
oil is a polluting energy source
air pollution is a major health issue
water pollution-the quality of rivers and oceans go down
radiation is from nuclear power or weapons.
noise pollution is a problem for modern life. serious threat to our quality of life
alternative options:
solar power-rely on sun
wind power-large amount of land for large amount of energy
hydroelectric energy-gravitational potential of elevated water
tomorrow we will continue with petsche's group
