What is pollution and its kinds?
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
The different types of pollution are:
- Air Pollution. Air pollution is the contamination of the natural air by mixing it with different pollutants such as harmful fumes and chemicals.
- Water Pollution.
- Soil Pollution.
- Noise Pollution.
- Radioactive Pollution.
- Light Pollution.
- Thermal Pollution.
- Visual Pollution.
- 14 billion pounds (6B Kg.) of garbage are dumped into the ocean every year. Most of it is plastic. Americans make up 5% of the world's population, and yet, produce 30% of the world's waste and use 25% of the world's resources. Human pollution has caused the average length of polar bears' penises to shrink.
- Over 1 million seabirds and 100,000 sea mammals are killed by pollution every year. People who live in places with high levels of air pollutants have a 20% higher risk of death from lung cancer than people who live in less-polluted areas.
- There are four main types of air pollution sources:
- mobile sources – such as cars, buses, planes, trucks, and trains.
- stationary sources – such as power plants, oil refineries, industrial facilities, and factories.
- area sources – such as agricultural areas, cities, and wood burning fireplaces.
Major forms of pollution include: Air pollution, light pollution, littering, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, water pollution.
- What comes to mind now to serve as reminders include the following:
- Stop smoking or at least follow the “No Smoking” sign.
- Use unleaded gasoline in your cars.
- Keep your car properly maintained to keep it in good running condition to avoid smoke emissions.
- Share a ride or engage in car pooling.
- Air pollution causes damage to crops, animals, forests, and bodies of water. It also contributes to the depletion of the ozone layer, which protects the Earth from the sun's UV rays. Another negative effect of air pollution is the formation of acid rain, which harms trees, soils, rivers, and wildlife.
- Others include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys.
