Air pollution is a change in the composition of air. Mainly due to smoke, dust, vapors or toxic gases that cause climate change, adversely affect human health or may damage the natural environment of many other species.

Air pollution is the cause of the risk of stroke, neurasthenia, cardiovascular disease, cancer, and a range of respiratory diseases such as asthma, pneumonia, even lung cancer is increasing. .

Air pollution is divided into two types, including outdoor air pollution and indoor air pollution. In particular, outdoor air pollution is a major factor causing serious impacts on the environment and human health in developed and developing countries. The cause of pollution comes from various sources such as traffic emissions, industrial plants, from agricultural production and some natural causes such as forest fires, desert dust, volcanoes.

Besides, we also face indoor air pollution. Pollution sources include cigarette smoke, charcoal, wood, chemicals in paint or cleaning products, air-conditioning gases and some substances in construction materials.

Nowadays, the development of human world causes causes many bad effects to the environment. We throw garbage everywhere, exploit too much natural resources or contaminate the air. Therefore, our environment is being seriously polluted and we need to protect it from now. First of all, we should reduce, reuse and recycle. Instead of using plastic bags, we can use leaves to wrap food. We can recycle plastic bottles, cans, paper to reduce garbage. Using public transports and decreasing the number of motorbikes and cars are also good ways to reduce carbonic in the air. Besides, we should purify contaminated lakes or rivers in order to lessen the pollution in the water.Last but not least, the gorvernment should propagandize about protecting the environment to everybody so that they can aware of it. Especially, we need to punish people who contaminate the environment with great severity. In conclusion, the Earth is our home so protecting it is everyone's responsibility.

Ngày nay, sự phát triển của thế giới loài người gây ra nhiều tác động xấu đến môi trường. Chúng ta vứt rác khắp nơi, khai thác quá nhiều tài nguyên thiên nhiên hoặc làm ô nhiễm không khí. Do đó, môi trường của chúng ta đang bị ô nhiễm nghiêm trọng và chúng ta cần bảo vệ nó từ bây giờ. Trước hết, chúng ta nên giảm thiểu, tái sử dụng và tái chế. Thay vì sử dụng túi nhựa, chúng ta có thể sử dụng lá để bọc thức ăn. Chúng ta có thể tái chế chai nhựa, lon, giấy để giảm rác. Sử dụng vận tải công cộng và giảm số lượng xe máy và ô tô cũng là những cách tốt để giảm lượng carbon trong không khí. Bên cạnh đó, chúng ta nên làm sạch các hồ hoặc sông bị ô nhiễm để giảm bớt ô nhiễm trong nước. Nhanh chóng nhưng không kém phần quan trọng, công việc bảo vệ nên tuyên truyền về việc bảo vệ môi trường cho mọi người để họ có thể nhận ra điều đó. Đặc biệt, chúng ta cần trừng phạt những người làm ô nhiễm môi trường với mức độ nghiêm trọng. Tóm lại, Trái đất là ngôi nhà của chúng ta nên bảo vệ nó là trách nhiệm của mọi người

There are various causes of increase in water pollution with industrialization and increasing population being the major one. With the increase in population around the world, the demand for various industrial products has been stimulated which has led to the increase in industrial waste. Many such industries discharge the waste into nearby water bodies without proper treatment which leads to the addition of harmful chemicals in the water body.

Modern methods of agriculture are also a leading cause because with the increase in use of chemical infused pesticides and germicides the soil is tampered and the water flowing through it gets mixed with these chemicals and loses its purity. These agricultural pesticides are a leading cause of eutrophication of freshwater lakes.

Other causes of water pollution includes acid rain, improper sewage treatment, discharging of hot water without cooling by thermal power plants, religious rituals such as disposing corpses into the rivers and various other urban and rural practices. Hence, these are the root causes of increasing water pollution. In order to eradicate the contamination of water these issues have be to be tackled with the help of advanced technology and scientific principles.

There are many ways to help protect our oceans and coast for future generations. Firstly, I think we shouldn't litter because this makes the sea pollute and endangers sea plants and animals. Some animals can be harmed if they eat these pollutants. We should place rubbish and plastic bags in proper dustbin. Secondly, I suppose the government should introduce laws to prohibit the killing of endangered animals and the destruction of the environment where the endangered species live. Finally, we should tell our friends, relatives or families not to purchase products made from body parts of endangered species. Be a smart shopper and choose your seafood responsibly. All in all, occeans should be protected so that the Earth will be a happy planet for us to live on.

Fresh water is the most important source of life on the earth. Any living thing may survive without food for days however it is impossible to imagine life without water and oxygen. The ever increasing human population enhances the demand of more water for purposes like drinking, washing, performing industrial processes, irrigating crops, arranging swimming pools and other water-sports centres. Water pollution is done by the people of all over the world because of increasing demands and competitions of luxuries life. Waste products from many human activities are spoiling the whole water and decreasing the amount of oxygen available in the water. Such pollutants are altering the physical, chemical, thermal, and biological characteristics of the water and adversely affecting the lives inside as well as outside the water.

When we drink the polluted water, harmful chemicals and other pollutants goes inside our body and deteriorates all the body organs functioning and puts our lives in danger. Such harmful chemicals also disturb the lives of animals and plants greatly. When plants absorb dirty water through their roots, they stop growing and die. Thousands of seabirds are killing because of the oil spilling from ships and industries. High level of water pollution is done due to the chemicals coming out of the agricultural usage of fertilizers, insecticides and pesticides. The effect of water pollution varies from place to place upon the type and amount of water contamination. The degradation of drinking water needs an urgent basis prevention method which is possible by the proper understanding and support from the end of each and every person living on the earth.

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.

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.
