Polyolefins such as polyethylene undergo slow degradation when placed in air. Degradation occurs by reactions with atmospheric oxygen that lead to the formation of carbonyl groups (groups containing oxygen), gradual….

If we are to take action against global warming, we must reduce carbon emissions. Explain how to reduce carbon emissions by using a. command-and-control regulation. b. an effluent tax. c. emissions trading.
A global agreement known as the Montreal Protocol led to the phase out of chlorofluorocarbons (CFCs), chemical compounds found in aerosol cans and refrigerants. CFCs may have contributed to the growing hole in the ozone layer. With a diminished ozone layer, there is an increased chance of skin cancer. Explain the effect of this agreement on the price of deodorants and air-conditioning. Also, is a ban on CFCs an effi cient approach to the ozone hole problem?
Explain the “Tragedy of the Commons,” as described by Garrett Hardin. Why does Elinor Ostrom disagree with Hardin’s prediction that fi sheries and other “commons” will collapse?
