Checking homework

Dear Jane,

Hi! How are you? I am writing to tell you about my recent trip to a wildlife reserve. I had a wonderful time and it was fantastic to see all the animals roaming freely. I especially liked feeding the baby giraffes. I saw lions and tigers lying in the sun and elephants having a bath. Next time you come visit I will take you there. I’m looking forward to hearing all your news. Please write soon.

Love,

Connie.

The rainforests are dying, rare plant and animal species are disappearing, rivers and seas are being contaminated, people are dying of hunger and the air is being polluted.

One of the major problems is the destruction of the rainforests in South America. They are home to half the world’s species and to millions of people. Moreover, the rainforests clean the air by absorbing carbon dioxide and giving out oxygen. The trees are being cut down for paper or to make room for cattle farms. As a result, birds and animals lose their homes and die. This destruction is also bringing about changes in the climate, air pollution, flood, drought, and famine.

Another big problem is water pollution. Can you imagine that swimming in the sea or drinking a glass of water is not safe? Factories are polluting our rivers and lakes with dangerous chemicals. Oil tankers are releasing thick, black oil into our oceans. Tons of industrial and domestic waste are poured into our seas. As a result sea life is threatened with extinction.

Air pollution is another important issue. The cars and factories in and around our cities are giving off dangerous fumes. More and more people have developed allergies and breathing problems. If we don’t do something now, our cities will become impossible to live in.

Fortunately, it is not too late to solve these problems. We have the time, the money and even the technology to prepare the way for a better, cleaner and safer future. We can plant trees and adopt animals. We can create parks for endangered species. We can put pressure on those in power to take action. Together we can save our planet.
