Acid
Rain
Secondary
By
seeing what acid rain is, what it does, and where it comes from,
students will come to understand the seriousness of the problem.
Dead lakes, dying forests, and crop damage mean a loss of billions
of dollars to the tourist, forestry, agriculture, and fishing
industries. Whatever steps are taken, the problem will be with us
for many years.
What
is Acid Rain? explains how sulphur and nitrogen oxide
emissions from sources such as ore smelters, power plants, and
automobile exhaust undergo chemical changes. Students will see
what areas are most susceptible and why.
Effects
of Acid Rain discusses the impact on the environment resulting
from prolonged exposure to acid rain. Aquatic life suffers and
gradually becomes extinct, forests experience slower growth,
certain crops become damaged, humans can suffer from bronchial
diseases or contaminated drinking water.
What
Can We Do? examines the complex web of economic, political,
environmental, and social issues surrounding acid rain. Even
though we have the technology to reverse acid rain, it is not a
simple matter to put that technology in place.
