Nature gave us all necessary resources to live and prosper. Now it is in danger and needs our help. What else we can do to protect environment? First of all this decisions must be made on governmental level and provide legal limitations for industries that emit a lot of greenhouse gases. We must unite together in order to protect the place we live in. People are an integral part of nature, we are dependent of it as we cannot imagine our life without nature. So why to destroy environment and bite the hand that feeds you? We must stop deforestation and plant trees on cut down areas. Trees are natural filter of air that absorb carbon dioxide and produce oxygen. Cutting down trees we deprive animals of their natural environment and the soil begin to grow in erosion. Planting trees will save birds and other animals.

We often make forced choices that are advertised on TV. Manufacturers try to rise their profits and sell more products. Sometimes we have so many unnecessary things we do not use. Imagine that you are moving your house, what are the necessary items you may need to live, only several bags. In reality the matter is opposite. There are a lot of things we do not use. People have to reconsider their views of life and promote healthy and ecologically friendly lifestyle. It is up to us to change situation for better and leave good legacy for generations to come.

Question: What do people have to reconsider?

Apromote healthy lifestyle

Bpromote healthy lifestyle

Cpromote ecologically friendly lifestyle

Read the following passage and mark the letter A, B, C, or D on your answer answer to each of the questions

An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely . Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled – a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions. Many of more important air pollutants such as sulfur oxides, carbon monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the concentrations of these pollutants were altered by various chemical reactions; they became components in biogeochemical cycle. Theseserve as an air purification scheme by allowing the compounds to move from the air to the water or soil on a global basis, nature's output of these compounds dwarfs that resulting from human activities.

However, human production usually occurs in a localized area, such as a city. In this localized regions, human output may be dominant and may temporarily overload the natural purification scheme of the cycle. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, as a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm.

For which of the following reasons can natural pollutants play an important role in controlling air pollution?

A. They function as part of a purification process.

B. They occur in greater quantities than other pollutants.

C. They are less harmful to living beings than are other pollutants.

D. They have existed since the Earth developed.
