       Currently, the earth is heavily polluted, causing water pollution and air pollution. The main cause of pollution is the lack of human awareness, but partly due to floods, storms, melting snow, drought, ... are also factors that seriously affect the above water sources. Earth. Surely this all of us can also feel. The consequences of pollution are severe. It caused acid rain in European countries, destroying everything in its path. In addition, air pollution causes a variety of respiratory-related illnesses that are very serious, and studies show that air pollution can increase the frequency of respiratory allergies, particularly. are people living in urban compared to rural residents. Children raised in heavily polluted areas are more likely to experience structural changes in the nasal mucosa. This can cause airway weakness, lung infection and inflammation. Not only that, even more horrible is that it is also causing a hole in the ozone layer of the greenhouse effect, making the earth gradually warming. The melting ice at the poles makes the sea level rise higher and higher, causing flooding in lowland areas. It can also cause cancer, one of the most terrible and difficult to cure diseases at that time. We can see the horrors of pollution, so let's protect the environment together, the consequences will be greatly reduced.

        English is a common language that is quite diffucult to understand and to learn. But there are many countries that speak English, making English as their native language. America is one of them. America is an English-speaking country. English is a common language in America. As  you know, America is very developed, and this developed country is using 1 international language, that is English. And as I know, most Americans speak Englishs .Due to the fact that a few hundred years ago, Colossians discovered. Although American and English are 1, but in there are still some words different from English like football (soccer) or some words with "u" missing word like color (colour) or neighbor (neighbour). English is very diverse, and our country is starting to use English as a second language.

When thermal pollution happens, the water temperature in streams, rivers, lakes, or oceans changes. It is one of the most serious types of pollution.

Thermal pollution can have many different causes. Power station are one factor. They use water in the nearby lakes or rivers to cool their equipment, which heats up the water. Then they dump the hot water back into its source. Thermal pollution may also happen due to the discharge of cold water from reservoirs into warm rivers.

Thermal pollution can have dramatic effects. Most aquatic creatures need a certain temperature to survive. Warmer water has less oxygen in it, and this can harm fish populations. Besides, warmer water can cause harmful algal blooms. This can change the colour of the water like in the first picture and, more seriously, the algea poisons the fish.

So, in many places, we build cooling towers like in the second picture to cool down the water from power stations.

Thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreasesoxygen supply and affects ecosystem composition. Fish and other organisms adapted to particular temperature range can be killed by an abrupt change in water temperature (either a rapid increase or decrease) known as "thermal shock."

 

Urban runoff—stormwater discharged to surface waters from roads and parking lots—can also be a source of elevated water temperatures.

Currently, the problem of pollution is getting more and more serious. Pollution has many types: air pollution, water pollution, soil pollution, ... All of them have a significant impact on human life, causing many health problems. So we need to act today to reduce pollution. First, we could form groups to collect rubbish on the beach and in public places because there are a lot of people who unconsciously throw their trash around. Then we can do the recycling methods or reuse them if possible. This will significantly reduce the persistence of hard-to-decompose waste. We can also propagate to people so that they can raise their awareness of environmental protection so that they can perform well. The State also needs to have sanctioning policies for individuals destroying the environment, factories that discharge waste into the environment without treating them first. The above are my solutions for environmental protection. Thanks for listening

Air pollution is a major change in the composition of the atmosphere, mainly from smoke, dust, soot, steam or air makes strange gas is not clean, there was a smell coming, reduced visibility, caused climate change, pathogenic for humans and creatures.

Air pollution caused more than 3 million people die prematurely every year, it threatens virtually all of the big city dwellers in the developing countries. According to Fox News 80% of cities in the world can not meet the standards of the World Health Organization on air quality, which is mainly concentrated in poor countries. WHO said the level of urban air pollution worldwide has increased by 8% despite improvements in some areas. This leads to the risk of stroke, heart disease, lung cancer and a variety of respiratory problems.
