A topic everybody talks about, yet no one prevents. Air pollution.
The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
Pollution causes both long term and short term health problems for humans. Examples of short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Other symptoms can include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. In the great "Smog Disaster" in London in 1952, four thousand people died in a few days due to the high concentrations of pollution
Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly. It is estimated that half a million people die prematurely every year in the United States as a result of smoking cigarettes.
However not only people are affected in terribly ways, wildlife is at a greater risk than most people understand.
Some air pollutants harm plants and animals directly. Other pollutants harm the habitat, food or water that plants and animals need to survive. Read on to learn more about how air pollutants harm plants and animals.
Acid rain harms
When acidic air pollutants combine with water droplets in clouds, the water becomes acidic. When those droplets fall to the ground, the acid rain can damage the environment. Damage due to acid rain kills trees and harms animals, fish, and other wildlife. Acid rain can destroy the leaves of plants like in the picture at the left. When acid rain soaks into the ground, it can make the soil an unfit habitat for many living things. Acid rain also changes the chemistry of the water in lakes and streams, harming fish and other aquatic life.
The thinning ozone
Air pollutants called chlorofluorocarbons(or CFCs) have destroyed parts of the ozone layer.The ozone layer, located in the stratosphere layer of Earth's atmosphere, shields our planet from the Sun's ultraviolet radiation. The areas of thin ozone are called ozone holes. Ultraviolet radiation causes skin cancer and damages plants and wildlife.
Tropospheric ozone
Ozone molecules wind up near the Earth's surface as a part of air pollution. Ozone molecules near the ground damages lung tissues of animals and prevent plant respiration by blocking the openings in leaves where respiration occurs. Without respiration, a plant is not able to photosynthesize at a high rate and so it will not be able to grow.
Global warming
Our planet is currently warming much more rapidly than expected because additional greenhouse gasses are being released into the atmosphere from air pollution. When fuels are burned, some of the pollutants released are greenhouses gasses. Through the process of photosynthesis, plants convert carbon dioxide into oxygen and use the carbon to grow larger. However, the amount of carbon dioxide released by burning fuels is much more than plants can convert.
Global warming is causing changes to the places where plants and animals live around the world. For example:
Near the poles, ice and frozen ground are melting. This causes changes in the habitat and resources for plants and animals living there.
Ocean warming, rising sea levels, runoff, and coral diseases are causing change in shallow marine environments such as coral reefs.
Global warming is causing less rain to fall in the middle of continents. This makes these areas very dry and limits water resources for plants and animals. [1]
Although I believe that global warming is due to our solar system moving to a different part of the universe that is warmer (considering that all planets, not just earth, are getting very warm {DETAILS HERE}) a big part of the heat is due to people polluting... I would estimate that in 50 years if we keep on polluting earth will be too unbearable foe human life.

A good example is the recent news, all they were showing on the news all day was Michael Jackson's funeral. One thing that bugs me is that when he was alive everyone hated him, but now that he's dead everyone loves him? And even more disturbing, why does everyone remember wacko Jacko but not Farrah Fawcett? She also died the same day Michael did. But unlike Michael you wouldn't vomit at the site of Farrah's face.
However many movies and music can get away with hidden messages. For example The Fifth Element, The Matrix, V for Vendetta and a few others, and many bands get away with exposing the truth through hidden messages including Rage Against the Machine, Marilyn Manson, Nine inch Nails and a few others
