1.Pollution: nói về những nguyên nhân và hậu quả của sự ô nhiễm và giải pháp
-----------------
Causes of environmental pollution
There are many causes of environmental pollution but perhaps the most impact is caused by human activity. In addition, environmental pollution can also occur due to natural impacts. As follows:

Due to waste from factories and industrial parks
Accordingly, factories and enterprises discharged untreated waste into the environment. Failure to treat wastewater before discharging it into the environment will cause serious water pollution.

In addition, in factories using fossil fuels as fuel, it creates CO2, CO, N0x, SO2 ... These emissions also cause serious air pollution, even causing house effect. glasses.
Due to toxic substances, plant protection chemicals
These are the excess chemical pesticides and fertilizers because people use them not to be thrown away and messy. These wastes will gradually infiltrate underground water sources, ponds and lakes ... This not only pollutes the soil but also pollutes groundwater. Even these toxic substances can be brought to the sea causing "red tide" phenomenon ...

Due to solid waste
In the process of national development, many facilities have been established to serve the increasing needs of people. This leads to an increase in solid waste.

The origin of solid waste can come from living, industrial or medical facilities. These wastes are not treated before being discharged into the environment and accumulate permanently in the environment. This causes air pollution, water pollution, groundwater pollution, soil pollution. At the same time, it also affects the ecosystem and human health.

Due to dust and smoke
It can be said that this is the main reason leading to air pollution. This situation often occurs in big cities, crowded vehicle density ...

Shortcomings in management
If pollution occurs, there is no lack of responsibility from the authorities. Specifically, the quality and efficiency of environmental technologies are not high.Consequences of environmental pollution
For human health
Effect of air pollution on human health
Air pollution has a significant impact on the respiratory system of the whole person. Emissions from vehicles are very harmful to the lungs. In addition, fine dust is the most dangerous pollutant because it exists for a long time in the air and disperses very far. Due to its small size, if it penetrates deep into the lungs, blood causes respiratory diseases, infertility ...

Air pollution also makes people dizzy, headache, cardiovascular ... The most affected people are the elderly, pregnant women, people who are sick, children under 15 years old ... Each group of subjects will be affected differently depending on health status and pollution levels.

In addition, heat waves or noise also cause certain harm to people. Noise is more likely to cause injury to the ear but also causes headaches, stress, nervous stress ...

Besides, climate change makes temperature rise abnormally tends to increase. This causes diseases such as heat stroke, heat-induced mice or even death.

Effect of water pollution on human health
Effect of water pollution on human health through 2 roads. First, eating / drinking must be contaminated water or plants and animals that are cultivated in polluted environments. Secondly, due to direct contact with polluted water environment.

Diseases caused by water pollution include diarrhea, cholera, typhoid, hepatitis, encephalitis, mosquito-borne disease, anemia ...

Effect of soil pollution on human health
The use of pharmaceutical chemicals in agricultural production is inevitable. However, if not used with the right dosage, it will lead to excess chemicals and soak in the soil.

This causes a biological imbalance between soil and plants. In addition to affecting the quality of agricultural products, soil pollution also causes poisoning of agricultural products. If people use these agricultural products, it will affect their health a lot.

The diseases that can be caused when using poisoned agricultural products are large liver, nervous system, genetic system, reduced IQ in children ...

For the ecosystem
Ecosystems are areas where populations live together and interact with each other. Environmental pollution will lead to changes in ecosystems.

The main threat and direct impact on the ecosystem is air pollution. Air pollution can lead to acid rain which destroys forests. Although it does not lead to extinction, the loss of plants will lead to reduced species structure.

For the socio-economic environment
Accordingly, environmental pollution can affect the socio-economic environment. Specifically:

Causing economic losses due to many diseases
Causing economic losses due to impacts on agricultural products and fisheries
Causing damage to tourism activities
Causing economic damage by improving the environment
Remedies for environmental pollution
Measures to overcome the first environmental pollution are people's consciousness. If people consciously throw away garbage in the prescribed places, do not litter litter the environment pollution will be significantly reduced. In addition, education and awareness programs for young children are required.
Limit use of detergents to prevent sewer clogging. You can replace the detergent with microbiological substances.

Completing the legal system on environmental protection and pollution prevention. There are strong sanctions to sanction.
Building an environmental management system according to international standards.
Regularly inspect, inspect and supervise the environment.
Improving professional skills for the team in charge of environmental work
Investing and equipping with modern technical facilities
Planting trees, causing forests
Burying and burning waste in a scientific way
Using environmentally friendly energy such as wind and sun
Through this can be seen, the environment is a very important factor in our lives. If the environment is contaminated it will also have a significant impact on our economic environment, ecosystem and health. Therefore, protecting the environment is to protect ourselves.
