Are your nightmares causing you significant distress?
Causes of Environmental Pollution Let us first take a look at the causes of environmental pollution: Industries have been polluting our environment especially since the beginning of the industrial revolution, as mentioned above, notably due to the increasing use of fossil fuels.
In the 19th century and for a significant part of the 20th century, coal has been use to make machines work faster, replacing human force. Though pollution by industries mainly causes air pollution, soil and water contamination can also occur. This is particularly the case for power-generating industries, such as plants producing electricity May they be a dam, a nuclear reactor or some other type of plant.
Also, the transportation of this energy can be harmful to the environment. We can take as an example the transportation of petrol through pipelines; if there is a leak in the pipeline, soil will automatically be polluted. At the same time, if the tanker transporting the petrol from its production plant to the place where it will be consumed leaks or sinks, the water will get contaminated.
Ever since men abandoned animal power to travel, pollution of the environment has become higher and higher. Its levels have only been increasing until now. Similarly to industries, pollution caused by transport can mainly be attributed to fossil fuels.
Indeed, humans went from horse carriages to cars, trains which, before electricity, used to be propelled by coaland airplanes. As the traffic is increasing every day, pollution follows that evolution.
Agriculture is mainly responsible for the contamination of water and soil. This is caused by the increased use of pesticides, as well as by the intensive character of its production. Almost all pesticides are made from chemical substances and are meant to keep diseases and threatening animals away from the crops.
However, by keeping these forms of life away, harm is almost always made to the surrounding environment as well. Furthermore, as agriculture gets more and more intensive to feed the increasing world populationmore environments and ecosystems are destroyed to make space for the crops.
Some of them, like rapeseed —used to make oil — demand a lot of space for a relatively small output. Trading activities including the production and exchange of goods and services.
Concerning goods, pollution can be caused by packaging which often involves the use of plastic, which is made from fossil fuels or transport, mainly. Finally, residential areas provide their fair share of pollution as well.
First, to be able to build homes, natural environment has to be destroyed in one way or another. Wildlife and plants are driven away and replaced by human constructions. As it requires the work of industries, construction itself is also a source of contamination of the environment.
Then, when people settle in, they will produce waste every day, including a part that cannot be processed by the environment without harm yet. Effects of Environmental Pollution Now that we have identified the main causes of environmental pollution, let us study the negative effects it has: The effects of environmental pollution on humans are mainly physical, but can also turn into neuro-affections in the long term.
The best-known troubles to us are respiratory, in the form of allergies, asthma, irritation of the eyes and nasal passages, or other forms of respiratory infections.
Notably, these well spread affections can be observed when air pollution is high in cities, when the weather gets hot, for instance.Dry mouth is a common side effect of many prescription and nonprescription drugs, including drugs used to treat depression, anxiety, pain, allergies, and colds (antihistamines and decongestants.
Bad breath, medically called halitosis, can result from poor dental health habits and may be a sign of other health problems. Bad breath can also be made worse by the types of foods you eat and.
Other causes. Diseases, such as some cancers, and conditions such as metabolic disorders, can cause a distinctive breath odor as a result of chemicals they produce. Chronic reflux of stomach acids (gastroesophageal reflux disease, or GERD) can be associated with bad breath.
Data and statistical information on health effects of cigarette smoking. Cigarette smoking harms nearly every organ of the body, causes many diseases, and reduces the health of smokers in general. 1,2. Quitting smoking lowers your risk for smoking-related diseases and can add years to your life.
1,2. Effects on the Ecosystem: In short, environmental pollution, almost exclusively created by human activities, has a negative effect on the ecosystem, destroying crucial layers of it and causing an even more negative effect on the upper layers.
Unit 6 • Cause-Effect Essays What is a great topic for a cause-effect essay? This type of essay may focus more on the causes or more on the effects, but most writers answer this question by thinking of an effect or a final result.
