1.The climate on the Earth as a planet has changed many, many times. The concern now is the impact that change can have on the human inhabitants (you and me). If the oceans warm a few degrees, what impacts can you see on the landmasses, biologic community, and human populations? Are these positive or negative changes? Why?
B. There is a global concern about the disappearing glaciers of Mt Kilimanjaro in Tanzania, others in Peru and parts of the Himalayas. Are these glaciers really important?
C. Class this is interesting. Do we as species really understand that there changes are going on and we need to change to adapt to the changing environment? Can we continue with “life” as we know it?
2. Outdoor air pollution is now monitored by the EPA as well as most states. States commonly will issue ozone warnings outlining the particulate content of the air and thus the air quality. Yet, indoor air pollution is not widely monitored. What is the difference between indoor and outdoor air pollution and which is a greater threat to you and your family? Why? Can you see all examples of air pollution?
C. The U.S. Congress passed the Clean Air Act in 1990 as a revision of the 1970 act to reduce air pollution. The act is designed to protect the environment and reduce air pollution through various regulated reductions in emissions. The act also defines the responsibility of the Environmental Protection Agency (EPA) to protect air quality and the stratospheric ozone layer.
Here in Georgia we have the Georgia Clean Air Force, an agency empowered to implement environmental protection measures in the state and follow the air quality standards set by the EPA and Georgia’s Environmental Protection Division.
Does your state have any programs or campaigns to support the Clean Air Act? If you are in another country, do you have a similar Act?
