IntroductionWhat is pollution?Pollution is the introduction of contaminates into a natural environment that causeinstability, discorder of brain, harm or discomfort to the ecosystem.Pollution hurt every livings being on the earth.Human are the biggest producers of pollution.Pollution is causing many illnesses.Thesis: what is pollution? What is cause of pollution? What is effect of pollution?Pollution: Pollution is the introduction of contaminates into a natural environment thatcause instability, disorder of brain, harm or discomfort to the ecosystem.Cause of pollution: primary pollution cause and secondary pollution causeEffect of pollution: pollution effect animal, human being, plant, tree etc Body paragraph 1Pollution is the introduction of contaminates into a natural environment that causeinstability, discorder of brain, harm or discomfort to the ecosystem. Pollution can take theform of chemical substance or energy, such as noise, hear or light. Pollution hurts everylivings being on earth. Human are the biggest producers of pollution. Pollution willshortern our life. There are main three types of pollution they are air pollution, waterpollution, and land pollution.Air pollution: air pollution could be in the form of the emission of harmful chemicalgases .For example,(carbon monoxide)Water pollution: water pollution could be in the form of any change in physical,chemical, and biological properties of water which has a harmful effect on living being.Land pollution: land pollution is can effect wildlife, plant, and human in many way.40% of American rivers and 46% American cake are too pollution for fishing, swimmingor aquatic life. Air pollution is come from a wild variety of source. Example vehicles,forest fire, dry soil erosion etc.
Body paragraph 2What are the main causes of pollution?The Human being itself is the main cause of pollution.We cause air pollution directly through our use of electricity, fuels, and transportation.We also cause air pollution indirectly, when we buy goods and services that use energy in theirproduction and delivery. Most of this air pollution we cause results from the burning of fossil fuels,such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles.People pollute the water with chemicals and other hazardous materials. Human agency may bethe most understated cause of water pollution. Of course we pollute passively on a large scale,merely by using the systems set up for us to exist and thrive.What can cause pollution?Trash, greenhouse gases, almost anything.Unfortunately, humans cause pollution from cars and factories and etcexhaust, smoke, litter and cutting down trees.Throwing household garbage, using old vehicles, smoking, using pesticides and insecticide1) Air pollution cause by the burning of fuel that directly releasehazardous chemical into air.2) Water pollution cause by directly incorporation of hazardouspollutants.3) Land pollution cause by domestic and nuclear wastes, industrialwater. Body paragraph 3
Environmental Pollution Effects on Humans Air Pollution Effects 1) Reduced lung functioning. 2) Reduced energy levels 3) Cancer Water Pollution EffectsWaterborne diseases caused by polluted drinking water1) Typhoid.2) Hookworm. Soil Pollution Effects1) Causes cancers including leukaemia.2) Lead in soil is especially hazardous for young children causing developmental damage tothe brain. Environmental Pollution Effects on Animals Effects of Pollution on Animals - Air Pollution1) Acid rain (formed in the air) destroys fish life in lakes and streams.2) Ozone in the lower atmosphere may damage lung tissues of animals. Effects of Pollution on Animals - Water Pollution1) Chemical contamination can cause declines in frog biodiversity andtadpole mass.2) Too much sodium chloride (ordinary salt) in water may kill animals.
Effects of Pollution on Animals - Soil Pollution1) Small life forms may consume harmful chemicals which may then bepassed up the food chain to larger animals; this may lead to increasedmortality rates and even animal extinction. Environmental Pollution Effects on Trees and Plants. Air Pollution1) Acid rain can kill trees, destroy the leaves of plants, can infiltrate soil bymaking it unsuitable for purposes of nutrition and habitation. Water Pollution1) May disrupt photosynthesis in aquatic plants and thus affectingecosystems that depend on these plants.2) Plants may be killed by too much sodium chloride (ordinary slat) inwater. Soil Pollution1) May alter plant metabolism and reduce crop yields.2) Trees and plants may absorb soil contaminants and pass them up thefood chain.
