To me, sustainability is the act in which people practice a good healthy relationship with the environment. The biggest problems we face would include over population, air pollution, and destruction of aquatic biodiversity.

1. Overpopulation has numerous affects on the environment. First, the need for food, strains the area's natural resources and the need for space depletes the total area of cultivable lands. Developing countries usually have a larger amount of people due to the higher death rates.

2. Pollution affects every area. Air pollution is the presence of chemicals in the atmosphere in concentrations high enough to harm organisms, ecosystems, or human-made materials. Some pollutants include carbon oxides, industrial smog, nitric oxides, ozone, and particulates. Harmful substances remain in the atmosphere for 2–14 days, depending on winds, precipitation, and other weather patterns. During this period, they descend to the earth’s surface in two forms: wet deposition consisting of acidic rain, snow, fog, and cloud vapor and dry deposition consisting of acidic particles. The resulting mixture is called acid deposition—sometimes termed acid rain.

3. Coral reefs form in clear, warm coastal waters of the tropics and subtropics. They are the world's riches and most diverse areas. When humans put nutrients from the atmosphere and from nearby urban and agricultural areas into the water ways, they can accelerate the eutrophication of lakes, a process called cultural eutrophication. Water sources have been continuously polluted and not taken care of. This leads to fish kills and coral bleaching. Both of which are harmful to the ecosystem.
