Nutrient pollution also can cause algae blooms which cause serious environmental problems affecting aquatic ecosystems, and which can cause dangerous health issues for animals and humans. Water pollution caused by sewage is an environmental problem. When sewage pollutes water it can be dangerous especially if it enters people 's source of drinking water as author Woodford states, "It is possible to catch illnesses such as hepatitis, typhoid, and cholera from river and sea water" (4). Chemical and radioactive runoff can be dangerous to humans as well. When water that is contaminated by chemicals is consumed by humans it can lead to sickness, paralysis or even death depending on the kind of chemical polluting the water and the concentration of the pollutant in the water.
It threatens the health, humans, plants, and animals. All water pollution is dangerous to the health of living organisms, but sea and river pollution can be especially harmful to the health of humans and animals. Rivers and seas are used as main sources of potable water by populations all over the world. Another serious result of this pollution is the effect of this pollution on trade in the polluted areas. This research studies cases which reflect different causes of sea and river pollution, how serious the pollution is and the effect of this pollution on trade, and the possible solutions applied by people and governments to this problem.
Atmospheric contaminants are derived from human practices, such as gas from automobiles, factories, and even chimneys. Pollutants do not only cause damage to our health, but they cause damage to the health of plants and animals as well. Sulfur dioxide and nitrogen oxide cause damage to leaves of crop plants and trees when they enter leaf pores. Exposure of leaves to air pollutants can also break down the waxy coating that helps prevent excessive water loss and damage from diseases, pests, drought, and frost. Water pollution is another problem our county faces.
Most of the litter and pollution affecting the world’s oceans also derives from plastic. His has had terrible consequences on many marine species, which can lead to consequences for those that eat fish and marine life for nutrients - including
The three main pollutions caused by mankind: Air, water and soil. Air pollution refers to contamination of air with poisonous toxic gases and particles released from industries. The three major causes are: Industrialization, smoke from fuels and deforestation. Gases released from industries cause a severe air pollution because, the substances contain more chemicals which are hazardous to human, animal and even to plant life. Smoke released from fossil fuels, petrol and vehicles also creates trouble to the environment as, they contain more carbon- dioxide which effects the human health like breathing and lung diseases.
The lack of oxygen kills animals and other organisms that live in the water. Many harmful chemicals are in industrial waste. These can become drinking water pollutants if not well managed. Car exhaust creates a wide range of gases and solid matter. This causes global warming, acid rain, and it harms the environment and human health.
According to Sharma (2005), water pollution is alteration in physical, chemical and biological characteristics of water which may cause harmful effects on human and aquatic biota. Industrial waste, oil leakage and chemical and pesticides are some of the sources of water pollution. Industries produce a large amount of waste that contains toxic chemicals. Most of the industries do not have proper waste management system and the waste goes into drain and later into sea. It leads to the increasing of temperature and mineral amounts in water.
Toxic dust is another repercussion created by soil pollution. This will pollute the environment and have serious health implications, in relation to people and animals. Other negative impacts include chemistry change (in soil) which can occur as a result of the existence of harmful chemicals, even if present at low concentrations. This has the ability to change the metabolism of micro organisms and arthropods which reside within the soil. This then eradicates a portion of the food chain, which can have serious consequences for consumer and/or predator species.
For those who fear "the end of the world," acid rain may pose a threat as it creates a bad environment for both animal and human. And for those who care about our planet, maybe it is about time we stop destroying it and give something back to Mother Earth. There are numerous causes of acid precipitation, several of these are insignificant and accumulate into severe cases. However, there are also some sources that are menacing by itself, sources such as industrial emissions. In some cases, acid rain is caused when industrial fumes mix with moisture in the atmosphere.
Pollution damages not only the earth but the creatures who live on it like humans, Polluted air and water can cause diseases to form in people like Asthma and Gastroenteritis. While Asthma and Gastroenteritis are very common and
