a. Environmental problems: What are they?

b. Environmental protection: How important is it?

c. Environmental solutions: How practical are they?

The environment we live in is facing many serious problems. We need to be aware of these problems so that we can find ways to protect nature.

A. Global warming is the rise in the average temperature of the earth's atmosphere. It is one of the biggest issues facing humans today. It can have serious consequences such as rising sea levels, polar ice melting, and extreme weather events like floods or heatwaves.

B. Another environmental problem is the cutting and clearing of natural forests. The loss of forests can have a negative impact on the environment. It can damage the natural habitats of many animals and put wildlife in danger. It can also destroy the natural soil and lead to climate change.

C. Air pollution is also a serious problem. It is mainly caused by waste gases that come out of vehicles, machines, or factories. When these harmful gases combine with the water in the air, they come down as rain or snow, which can damage all forms of life. In addition, this problem leads to global warming and climate change. It is also a major cause of respiratory diseases or even lung cancer.

D. Around the world, the number of endangered animals is rising. Many of them disappear because of pollution and climate change. In addition, humans illegally hunt and kill animals, and catch too many fish at once. This is upsetting the natural balance of ecosystems, which can be harmful to all living and non-living things.

Read the essay. What is the writer's opinion about the problem? How many solutions does she propose?

Most people agree that the lack of exercise in teenagers' lives is a serious problem. But what are the causes of this problem and what can we do to address them?

I strongly believe that today's teenagers spend too much time playing on electronic gadgets. They hardly ever do outdoor activities and this is why many of them do not get enough exercise. What is more, many teenagers are overweight and this makes them less willing to do exercise.

In order to tackle this problem, a number of measures are necessary. In my view, it is unrealistic to limit the amount of time teenagers spend on gadgets. What I propose instead is that we make sure school canteens only serve healthy food. Furthermore, I would strongly recommend that we give all teenagers free membership of their local sports facilities.

To conclude, lack of exercise can cause long-term health problems, so it is vital that we act now. It seems to me that the measures I propose will begin to remedy the situation.

2.There is so much smoke in the air that it is..........to live in many of the world's cities (health)
