owadays, water pollution is a very important case. They are very harmful to the ecosystem such as: mass death of fish, withered green plants, etc. Therefore, we should have a good sense of protecting clean water sources. such as: do not throw garbage into rivers or lakes; Do not dump the wastewater from the factory into ponds, lakes, ... I am writing this article to hope everyone can protect the water environment.
Almost all types of water pollution are harmful to the health of humans, animals and plants. Water pollution may not harm our health immediately but could harm after long term exposure. Different types of water pollution affect health in different ways:
Heavy metals from industrial processes can accumulate in nearby lakes and rivers. They are toxic to marine organisms such as fish and shellfish, and subsequently to those who eat them. Heavy metals can slow growth; birth defects and cancer.
Industrial waste often contains many toxic compounds that are harmful to the health of seafood. Some of the toxins in industrial waste can have only mild effects while others can be fatal. They can cause immunosuppression, fertility failure or acute poisoning.
Pollutants from wastewater often lead to diseases that infect aquatic and terrestrial organisms through drinking water. Microbiological contamination is a major problem in developing countries, with diseases such as cholera and typhoid fever being the main cause of infant mortality.
Sulfate particles from acid rain can harm the health of organisms in rivers and lakes, which can lead to death.
The suspended particles in fresh water reduce the quality of drinking water for humans and the aquatic environment for marine organisms. Suspended particles can often reduce the amount of sunlight that passes through the water, disrupting the growth of photosynthetic plants and microorganisms. As a way to reduce water pollution, more advanced technical cleaning is needed. Some developed countries have wastewater treatment plants that remove pathogens. Maintenance, replacement and repair of leaky and faulty wastewater treatment infrastructure. Household septic tanks need to ensure pre-treatment on the spot before seeping into the soil.
XV. Read the passage and answer the question.
A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs. You need transportation, electricity, food, clothing, and other goods. CO2 is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.
Carbon dioxide is also called greenhouse gas, which causes global warming. That is the reason why the carbon footprint is a very poweful tool to understand the impact of personal behaviours on global warming. If you want to contribute to stop global warming, the reduction of your personal carbon footprint is essential. Fist, you can reduce your carbon footprint by driving less. When possible, walk or ride a bike to avoid carbon emissions completely or use public transport in order to decrease CO emissions. Second, support using clean energy sources such as wind, solar, geothermal energy and biogas. Finally, reusing or recycling items you no longer use is also a good way to reduce your carbon footprint.
1. What is a carbon footprint?
A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs.
2. How is CO2 produced?

Stress is a harmful phenomenon that can cause various kinds of problems in our society. Stress-related problems such as stomach ulcers, suicide and violence are good examples. This essay will describe the reasons for stress presence in our society and will explain how to overcome this problem.
There are different causes of stress which are very common in our society. At school and in the office, people face various stressful competitive situations. From their early schooling years to their professional life, people spend a lot of time trying to get success either by achieving high grades or by progressing at work. Moreover, even at home, people might feel stress when they watch too many advertisements on television. They might find it difficult to cope with the pressure of wanting to buy different products and their inability to do so. Mobile phone companies, for example, persuade young people to change their phones regularly to keep up with the new technology. As a result, they start spending a lot of money on their phones and may even find themselves in a debt crisis that causes more stress
However, different solutions are available to combat this problem. An individual should consider relaxation and less exposure to stressful situations. It is effective to try to release as much stress as you can from time to time. For example, sleeping for a long time on the weekend or spending time doing your favourite hobby is relaxing and therefore reduces stress. In addition, people should try to avoid situations that may become a source of stress later. One way to do this would be to pay less attention to TV commercials and have more realis expectations of the products they can afford.
In conclusion, people may suffer stress for different reasons competition and the negative influence of TV advertisements. Therefore, people ought to aware themselves of this issue and try to overcome the problem. Unless people start avoiding and releasing stress, the problems that this phenomenon creates will continue to grow.
