environmental problems left over from before–stuff that was dumped and maybe buried on the
property that must be cleaned up before development? Does the property contain wetlands that
cannot be built upon? Will construction affect existing water flows so that the water rights of
surrounding property owners could be affected? Similarly, will development change the direction
and quantity of water runoff, so that neighboring property could be flooded?
GLOBAL ENVIRONMENTAL ISSUES—Certain environmental issues affect many nations
and exist across borders and are best handled in the international arena. Global cooperation in
areas of concern is important to all nations.
The Ozone—Excess ozone in the air we breathe is caused largely by automobile exhaust. Too
much ozone at low atmosphere levels is a problem. Ozone depletion in the upper reaches of the
atmosphere is caused by a different substance: clorofluorocarbons (CFCs). CFCs, such as freon,
are used as refrigerants and in some plastics. If large quantities of CFCs are present in the
atmosphere they eat a hole in the ozone layer, exposing life on earth to increased ultraviolet
radiation. Domestic Agreement—After evidence was presented in the mid-1980s that a hole in
the ozone layer existed over Antarctica, U.S. manufacturers of CFCs agreed to stop production of
the product. The Montreal Protocol of 1987, an international agreement, froze CFC production at
1987 levels and cut production 50% by 1998. The Protocol was revised in 1990 banned CFCs
and halon (a fire fighting chemical) by 2000. In the U.S., CFC and halon production ended in
1995. This phaseout of CFCs cost the world economy approximately $200 billion.
International Cooperation—A number of pressing environmental issues require the
cooperation not only of industrial nations (as was the case for CFCs) but also of less developed
nations. The Montreal Protocol established a fund, paid for by wealthier nations, that can be used
to help poorer nations who are hurt by the CFC ban. This represents wealthy nations buying
environmental protection/ environ-mental rights from poorer nations. This is likely to be an
important trend in global environmental issues, especially given the very poor state of the
environment in many nations, the ex-communist nations particularly. For example, it is estimated
that the unified German nation spent $100 billion by 2000 to start cleaning up the former East
Germany. Other major global environment issues include global climate change and vanishing
rainforests.
International Perspective: CITES: Global Species Concerns May Conflict with Local
Interests
The Convention on International Trade in Endangered Species is endorsed by most nations.
Countries agree to comply, but it is not a binding treaty so there is little consequence for ignoring
it. The transport of endangered species is prohibited and is enforced at the border at the U.S. and
some countries. Some of the protected species, such as the rhino, are actively traded or, more
commonly, parts of their bodies are traded for alleged medicinal benefits. It is a good source of
income for poor people and buyers think there are benefits to consumption. Alternatives that give
those who live near endangered species incentives to protect them need to be developed to help
encourage conservation.
Climate Change—Kyoto treaty was signed by numerous nations that claim they will reduce
greenhouse gases by 2008-12. The U.S. has not ratified the treaty. [Note: The nations that have
signed the treaty have been all talk, no action, about reducing emissions. Per capita emissions
have been rising faster in the E.U., where the treaty was ratified, than in the U.S.]
CASE: Massachusetts v. EPA (S.Ct., 2007)—Twelve states and some private groups sued the
EPA contending that it had an obligation under the Clean Air Act to regulate greenhouse gases
