Individuals often throw out goods without realizing that they could be dangerous for the environment. Models are predicting that over the next century the global temperature will rise by several degrees.ĭ. Current fears stem largely from the fact that global warming is occurring at such a rapid pace. By trapping heat, the greenhouse effect is warming the planet and threatening the environment. Global warming is called the greenhouse effect because the gases that are gathering above the earth make the planet comparable to a greenhouse. Output controls are also more expensive, making them less desirable to tax payers and polluting industries.Ĭ. Input controls are usually more effective than output controls. There are two main types of pollution control. In order to accomplish this, governments, scientists and environmentalists are using or testing a variety of methods aimed at reducing pollution. Air pollution has many disastrous effects that need to be curbed. Some scientists think that human production is primarily responsible, while others cite natural causes as well.ī. The problem is that acid rain, one of the most important environmental problems of all, cannot be seen. As a result, this global pollution issue causes great debates between countries that fight over polluting each other’s environments. Acid rain moves easily, affecting locations far beyond those that let out the pollution.
