Read the passage carefully, then choose the correct completion.
Last year I went to Nepal for three months to work in a hospital. When the hospital let me have a few days' holiday, I decided to go into the jungle and I asked a Nepalese guide, Kamal Rai, to go with me. In the jungle there was a lot of wildlife, but we were trying to find big cats, especially tigers. We climbed onto the elephants' backs to get better view, but it is unusual to find tigers in the afternoon because they sleep in the heat of the day. Then, in the distance, we saw a tiger, and Kamal told me to be very quiet. We crept nearer and found a dead deer still bleeding. This was the tiger's lunch! Suddenly. I started to feel very frightened.
We heard the tiger a second before we saw it. It jumped out like a flash of lightning, five hundred kilos plus and four meters long. I looked into its eyes and face, and saw right down the animal's throat. It grabbed Karnal's leg between its teeth, but I managed to pull Kamal away. One of our elephants ran at the tiger and made it go back into the grass, so we quickly escaped to let the tiger cat its lunch. That night it was impossible to sleep!

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.
