Sustainability

In the broad sense of the word, sustainability is the capacity to endure. When defining sustainability in the ecology meaning, it deals with how biological systems remain diverse and productive over time. The potential for long-term improvements in well-being, which in turn depend on the well being of the natural world & the responsible use of natural resources. Sustainability applies to life on Earth. It consists of three pillars: environment, society, and economy.



One issue is air pollution. Humans impact greatly on this problem. An example of this is air pollution in cities. Toxic chemicals like nitrogen oxides, sulphur oxides, volatile organic compounds, and particular matter that produce photochemical smog and acid rain, and the chlorofluorocarbons that degrade the ozone layer.

A solution to this problem is hybrid cars. Electric cars would cut down on the exhaust put into the air. Exhaust from cars is a major contribute to air pollution. Instead of gas stations, there could be places to charge cars. Also, another way of keeping electric cars going is for them to have an internal combustion engine & an electric motor. Not using gas for cars not only benefits the air, but it also benefits the economy by us not depending on foreign oil as much. It might take awhile for this solution to be put into action, but until then, people could carpool to work. If you carpool with four other people for example, that's four less cars on the road contributing to air pollution. In the long run, this really does make a difference. Imagine if everyone carpooled. Converting to cleaner fuels also would help out this issue. Cleaner fuels that are made include: bioethanol and biodiesel. Buying electrostatic precipitators help out air pollution in the home. These are electric filters that take out dust and other particles from the air that are not healthy. This benefits the environment, but it also helps out people with medical issues such as athma.
