Points to remember before you participate in a Essay Writing:
- Divide your essay into 3 parts (each in a different paragraph).
- Introduction -> content -> conclusion.
- Give a space after the full stop (.) and comma (,).
- Capitalise the next word after the full stop.
- Frame small sentences as it will prevent you from making mistakes. Avoid extra spaces.
- Your essay should not be less than 300 and not more than 400 words
- The essay should be the original work and it should not be copied from anywhere.
Environmental pollution is the currently biggest challenge the world is facing. There are so many sources of pollution and each one has its own effect on the environment and living organisms. This causes of pollution's are not just limited to fuels and carbon emissions. There are many other types of pollution including chemical pollution into bodies of water, soil and air through improper disposal practices and agricultural activities.
Air pollution is a major problem faced by many countries. The burning of fossil fuels for transportation and electricity produces both primary and secondary pollutants. The fumes from car exhausts contain dangerous gases and particulates including hydrocarbons, nitrogen oxide and carbon monoxide. these gases rise into the atmosphere and react with other atmospheric gases creating even more toxic gases.
The improper disposals of industrial wastes are the sources of soil and water pollution.
Water pollution is caused by wastewater, sewage and fertilizers. The high levels of nutrients in these sources end up in bodies of water and promote algae and weed growth,which can make the water undrinkable and depleted oxygen causing aquatic organisms to die. Pesticides and herbicides applied to crops and residential areas concentrate in the soil and are carried to ground water by rainwater and runoff. Industrial waste is one of the main causes of water pollution, by creating primary and secondary pollutants including sulfur, lead and mercury, nitrates and phosphates and oil spills.
Land pollution is the destruction of land as a result of human's activities and the misuse of land resources. Soil is also polluted through leaking underground septic tanks, sewage systems, the leaching of harmful substances from landfill, and direct discharge of waste water by industrial plants into rivers and oceans. Over farming and over-grazing by agricultural activities causes soil to loose its nutrient value and structure causing soil degradation another type of soil pollution.
Noise pollution can cause stress, anxiety, headaches, irritability, hearing loss, and sleep loss resulting in decreased productivity. Oil drills, sub marines and other vessels on and in the ocean can cause excessive noise that has resulted in the injury or death of marine animals, especially whales. Many mammals, insects, birds and reptiles are photo periodic meaning their movement, mating growth and development, and eating cycles are regulated by natural light patterns. Light pollution can interfere with these natural behaviors and cycles, causing a decrease in wildlife populations.
Radiation pollution is any form of ionizing or no ionizing radiation that results from human activities. The most well-known radiation results from the detonation of nuclear devices and the controlled release of energy by nuclear power generating plants. Other sources of radiation include spent fuel prepossessing plants, by products of mining operations and experimental research laboratories. Increased exposure to medical X-rays and to radiation emissions from microwave ovens and other household appliances, although of considerably less magnitude, all constitute sources of environments radiation.
Protecting the environment is a long and daunting task, requiring continuous planning , governmental policies and public and industrial participation. By decreasing waste, implementing recycling policies, banning dangerous agricultural chemicals and develop safe renewable energy we can reduce the amount of pollution. The population over increasing, pollution problems are only going to get worse unless we do something about it.
