5. What is the Kyoto Protocol?
Specific international standards that every nation must comply with in regards to emission
of gases
Standards that every nation must comply with in regards to the emission of pollutants into
streams and drinking water supplies
A controversial treaty proposed among industrialized nations to slow global warming
A United States law that regulates the emission of harmful gases into the atmosphere
without a permit
An alliance of scientists worldwide working to prove the harmful effects certain gases can
have on the environment
6. Which of the following best describes the relationship between drinking water quality and water
pollution?
Water from surface reservoirs and water from underground aquifers can both be harmed
by water pollution.
Water pollution most likely affects the quality of drinking water from surface reservoirs
such as rivers and lakes since these are the primary sources of our drinking water supplies.
Very few drinking water systems in the United States are in violation of federal safety
standards, as these water pollution problems are found only in less industrialized
countries.
Water pollution is generally less of a factor in industrialized areas, because most industries
carefully clean potentially harmful discharges in order to protect drinking water quality.
Although water pollution usually affects the fish, animals, and plants living in and near the
bodies of water, it rarely impacts the quality of the drinking water directly.
7. Which of the following is not a major environmental issue affecting land?
8. What argument lies at the heart of environmental battles over endangered species habitats throughout
the world?
Most people realize that the loss of any one species will not threaten the entire ecosystem
or create a decline in biodiversity.
Global research indicates that declining numbers of plant species have little impact on the
overall ecosystem.
People argue that human beings are more important than any one species of plant or
animal.
There is a significant burden incurred by complying with endangered species laws, and the
laws do little to protect the species anyway.
People argue that there are few benefits received from biodiversity, and no regulation is
needed to protect endangered species.
