Perilous pollutants may contain various types of impurities including harmful chemicals, dissolved gases, suspended matters, dissolved minerals, and even microbes. All the contaminants reduce the level of dissolved oxygen in the water and affecting the lives of animals and human beings to a great extent. Dissolved oxygen is the oxygen present in water required by the aquatic system to continue the lives of plants and animals. However biochemical oxygen is the demanded oxygen by the aerobic micro-organisms to oxidize organic matters of wastes. Water pollution is caused by two means, one is natural water pollution ( due to the leaching of rocks, decay of organic matters, decay of dead matters, silting, soil erosion, etc ) and another one is man-made water pollution ( due to the deforestation, set up of industries near large water bodies, high level emission of industrial wastes, domestic sewage, synthetic chemicals, radio-active wastes, fertilizers, insecticides, pesticides etc )

Parallel about develop society, our environment is becoming bad to worse. In old times, people lived in a fresh environment so they can live so strong until die. But now, people always have many sick from mild to heavy. Do you think why? Because many people were lost sense of protection, littering indiscriminately, deforestation too much,... Don't get too late, right now we can grow more trees, punish acts polluting the environment,...Let's live more meaning

Noise pollution is a very special type of pollution.
(Definition:) It is known to be the exposure to some high sound levels that may lead to adverse effects in humans or other living organisms. (Causes:) Noise becomes harmful when it exceeds 75 decibels (dB), such as the sound at a busy residential road. Noise is painful when above 120 dB, such as the sound of a jet taking off. (Effects:) Noise pollution affects not only the hearing but also the nervous system. It can make us deaf or have high blood pressure, nervousness, hearing loss, and sleep disturbances.

The second is from people acting as vehicles emitting dust and smoke. Effect:harmful to humans , making animals and plants unable to live, causing serious illness. Sollution: planting trees, improve human working machines, educating people on mesures to raise awareness of environmental protection

Of course, there are all different kinds of environmental problems and I do not know which problem you want discussed. I will write about global warming.
One of the major environmental problems today is global warming. It is caused by an excess of carbon dioxide in the atmosphere. This causes what is known as a "greenhouse effect."
The major effect of this greenhouse effect is to raise the temperature of the world as a whole. If this continues, climate patterns around the world will change. In addition, sea levels will probably rise, which will be bad for low-lying areas.
There are many possible solutions, all of them have to do with emitting less carbon dioxide -- either by using less energy or by finding energy sources that do not emit carbon dioxide.

Pollution has become a major environmental issue as it has created lots of health hazards to the people and animals of any age group. In the recent years the rate of pollution is increasing very sharply because of the industrialized waste material mixing out directly into the soil, air and water. However, in our country full attention is not getting paid to control it. It needs to be tackle seriously otherwise our future generations would suffer a lot.
Pollution is classified into many categories according to the natural resources getting affected such as air pollution, soil pollution, water pollution, noise pollution, etc. Rate of pollution is increasing due to the selfishness of the human being to earn more money and to fulfill some unnecessary wishes. In the modern era where technological advancement is given more priority by the people, everyone has forgotten the real discipline of life.
Continuous and unnecessary cutting down of the forests, urbanization and large production through industrialization has involved as a huge causes of the pollution. Harmful and poisonous wastes created from such activities causes irreversible changes to the soil, air and water which ultimately push lives towards pain. This big social issue needs a public level social awareness programme to destroy by its root to get complete relief.

Pollution is the mixing of some harmful or poisonous materials into the natural resources available on the earth. It affects the ordinary living of the living things on this planet by disturbing the natural life cycle. Pollution can be of many types like noise pollution, air pollution, soil pollution, water pollution, etc. Air pollution is increasing day by day because of the growing number of automobiles, release of poisonous gases, smoke from industrial companies, finely dissolved solids, liquid aerosols, etc in the atmosphere. The air we breathe every moment causes several lungs disorders.
In this way soil and water pollution is also cause by the mixing up of the sewage water (having germs, viruses, harmful chemicals, etc) in drinking water, some dangerous agrochemicals such as pesticides, fungicides, herbicides, organic compounds like ether, benzene, some radioactive materials including radium and thorium, solid wastes (industrial ashes, rubbish, garbage), etc. We need to follow all the control measures implemented by the government to check its harmful effects.

Các chất gây ô nhiễm nguy hiểm có thể chứa nhiều loại tạp chất bao gồm các hóa chất độc hại, khí hoà tan, các chất lơ lửng, các khoáng chất hòa tan, và thậm chí là các vi khuẩn. Tất cả các chất gây ô nhiễm làm giảm mức oxy hoà tan trong nước và ảnh hưởng đến cuộc sống của động vật và con người ở mức độ lớn. Oxy hòa tan là oxy hiện diện trong nước mà hệ thống thủy sinh yêu cầu để tiếp tục cuộc sống của thực vật và động vật. Tuy nhiên oxy sinh học là loại oxy mà các vi sinh vật hiếu khí cần để oxy hóa các chất hữu cơ của chất thải. Ô nhiễm nguồn nước gây ra bởi hai phương tiện, một là ô nhiễm nguồn nước tự nhiên ( do sự rửa trôi của đá, sự phân hủy của các chất hữu cơ, sự phân hủy của các chất chết, xối xối, xói mòn đất,… ) và một là ô nhiễm nguồn nước do con người gây ra ( do nạn phá rừng, khai thác các ngành công nghiệp gần các vùng nước lớn, phát thải cao các chất thải công nghiệp, nước thải sinh hoạt, hóa chất tổng hợp, chất thải phóng xạ, phân bón, thuốc trừ sâu, thuốc trừ sâu,…)

On a global perspective in our modern world, pollution has become a nightmare for every country all around the world. Well, firstly when mention the phrase it is important to re-define it, then " What is actually pollution". Let's make it basic by imagine a river full of trash, the the biodiversity under the water won't remain long. This is the most classic type of pollution, water pollution. Water is an essential source of energy, life, acting as an major role on the economic, without water, life won't exist. However, human us make it over use for too many purpose, we accidentially destroy our natural resource through industrilization activities, waste chemicants, these factors gaining and contribute to the pollution density on parular area that water current flow through. Now that we know it significant setting, it is our responsibility standing up against for our rights as humanality, water is the only lasting resource on Earth to maintain life, our permission is to reserve it and keep it use for the after generations
