Pollution And Its Effects On The Environment – Most of the air pollution, harmful gases and particles in the air, that affect national parks is created outside park boundaries.

Mobile sources account for more than half of all air pollution in the United States and the primary mobile source of air pollution is the automobile, according to the Environmental Protection Agency. Stationary sources, such as power plants, emit large amounts of pollution from a single location, these are also called point sources of pollution. Area sources are made up of many smaller pollution sources that are not a big problem by themselves, but when they can be considered as a group. Natural sources can sometimes be significant, but usually do not create persistent air pollution problems like the other source types can.

Pollution And Its Effects On The Environment

Pollution from human and natural sources is often created in one place and transported through the air. Sometimes chemical reactions in the atmosphere change pollutants before they are deposited. Pollutants in the air can create haze, making it harder to see, and pollutant deposition can have biological effects. areas experience these effects just like other places. Location and even the time of year can determine which pollution sources are the most important for each park.

Parks downwind of power plants that lack modern pollution controls have increased smog. Emissions from car and truck emissions, as well as industrial processes such as oil and gas development, give rise to increased ozone concentrations. Summer fires can also reduce visibility in areas. There are even examples of pollutants that originated from other countries and were transported thousands of kilometers arriving at parks. The effects of this pollution can be seen as haze and through negative biological effects. Know more about effects of air pollution on nature and visibility, and human health. Water is one of the basic needs of a human being. We use it to quench our thirst, give energy to our body and wash our clothes, dishes and other parts of our house. Without water we will die.

As years passed, the population began to grow, and bodies of water became polluted. Water pollution occurs when large bodies of water such as groundwater, oceans, rivers and lakes are contaminated with harmful chemicals and bacteria. This is due to the waste product that has been thrown directly into the water.

Indeed, water pollution is one of the major crises facing the world today, and it affects millions of people who do not have access to clean drinking water. The government spends time and effort to focus on water pollution and its effects to protect the people.

We need water to survive and to do that, and we need to take different measures to save some of the resources we have today.

What Is The Cause Of Environmental Pollution

So in this article we will discuss the causes and effects of water pollution and some of the solutions to be done we can start immediately.

Over the years we have witnessed the exodus of people into towns and cities. People started building houses, roads and large industries. After that, there is a physical disturbance of the land, and factories started dumping their chemical waste into the water bodies.

Large factories flush waste products into the water, which is one of the main causes of ocean pollution.

On the other hand, ordinary people also cause water pollution and not only large factories. Everyone is guilty of pouring chemicals or detergents into their drains or toilets. This toxic pollutant can enter the wastewater from highway runoff.

Does Air Pollution Cause Climate Change?

Highway runoff is usually covered in toxic chemicals such as contaminated fuel, chemical additives, brake fluids and exhaust emissions. When it rains, these chemicals are washed into the drains and the rivers.

With this, the school of fish can be killed overnight. According to studies, the runoff of the highway in one year is equivalent to an oil tanker. Some debris from the highway ends up in the drains, and they can contaminate the groundwater or collect in the land near the road. So it becomes more and more toxic year after year.

Nowadays, sewage waste is becoming a big problem due to the growing population of the world. Improper disposal can lead to various water-related diseases that can kill adults and children.

The problem of sewage does not stop easily. Once you flush the toilet, the waste has to go somewhere, and even if it comes out of the sewage system, there is still waste to pick up. Thus, sewage waste is dumped into the oceans.

Environmental Pollution And Its Effect On Health

In theory, sewage contains a natural substance that can be easily broken down by the environment. 90% of sewage contains water. In practice, however, sewage contains all the other chemicals such as paper, plastic and pharmaceutical products that they flush down the toilet.

Even when people are sick, they carry viruses with them. So the sewage they produce carries those viruses and spreads it in the ocean. Today it is possible to catch typhus, hepatitis and cholera from the ocean and river.

Farmers have also used harmful fertilizers to produce more and cope with the demand of the growing population. This causes an algae bloom in the water. If the oxygen level of the water increases, it can also cause the extinction of underwater plants and fish.

Detergents are chemicals that are dumped into the ocean. On the other hand, polychlorinated biphenyls (PCBs) are highly toxic substances, and their traces are discharged into the environment today.

Effects Of Air Pollution On Natural Ecosystems

Lead is used in gasoline or gasoline, but it is restricted in some counties. Meanwhile, cadmium and mercury are still used in batteries. Recently, a chemical called Tributyltin (TBT) was also found in the affected water bodies.

In 1938, a Japanese factory released a huge amount of mercury metal into Minamata Bay. This heavy metal water pollution suffocated the fish stocks, and it took almost ten years for the problem to come to the attention of the authorities.

By then, locals have already consumed the fish, and about 2,000 residents were poisoned. More than 100 people were disabled and lost their lives.

High concentrations of radioactive waste can cause great alarm to the public. It can cause diseases like cancer which can eventually cause the death of a person.

How Air Pollution Has Put A Brake On Global Warming

In Europe, the biggest source of radioactive contamination is Sellafield and Cap La Hague. These companies dump radioactive waste into the ocean, which currents carry around the world.

Norway has received significant doses of radioactive contamination from Sellafield, and the government has repeatedly complained about the company. Both the Norwegian and Irish governments have continuously pushed for the closure of the plant for years.

According to studies, 12% of the oil entering the ocean comes from tanker accidents, while 70% of it comes from people spilling oil on land and standard shipping.

However, tanker oil spills are destructive because it releases large amounts of oil at the same time. In the United States, one of the largest oil spills occurred in 1989 when the tanker Exxon Valdez broke in the Prince William Sound in Alaska.

During this incident, approximately 12 million gallons of oil were dumped into the ocean. Around 1,000 to 2,000 sea otters and 250,000 seabirds were affected. Billions of salmon and herring eggs are also destroyed by the oil spill.

Today, plastic is used in almost all manufactured objects, from the clothes we wear, home goods and car parts. It is lightweight, and it floats easily. However, plastics are non-biodegradable, and they can affect the survival of marine life for a very long time.

Some people may say that plastics are not as toxic as other chemicals, but they also pose a danger to the fish, seabirds and other marine animals.

For example, plastic fishing lines and other waste materials can suffocate and suffocate a fish. About half of the world’s seabird population has also eaten plastic, and experts have found residues in their stomachs.

Water pollution can be caused by alien or invasive species that have been introduced into a new system where they do not belong. When outside their normal environment, they have no natural predators. They can run fast in the wild and overpower the common plants or animals that live in the place.

For example, the zebra mussels in the Great Lakes of the United States are carried by the waste water that is washed off the ships in Europe. Meanwhile, the Mediterranean Sea has been attacked by algae, while the Black Sea is a strange jellyfish.

Some forms of pollution include thermal pollution that comes from the power plants or factories, which causes problems in the rivers. The increasing temperature in the water can reduce the amount of oxygen in the water and reduce the aquatic life that the river can support.

The disturbance of sediments or the fine-grained powders that move from the rivers into the sea must also be taken into account. The water dams that are built as water reservoirs or to produce hydropower can reduce the sediment flow. This reduces the formation of beaches and flow of nutrients, while increasing coastal erosion.

What Environmental Factors Affect Health?

Meanwhile, increased sediments can also be a problem. During construction work, rock, soil and fine powders can enter and create rivers in large quantities
