Reading task
The wrld is in dangerOur wrld is in danger. We must d smething t prtect the envirnment. But, what are the main prblems we face?The greenhuse effectThe atmsphere arund the Earth is necessary fr all living things. It is like the glass f a greenhuse, letting sunlight in and keeping heat frm getting ut. Withut it, the Earth wuld be the same as the Mn — cld and lifeless.When we burn fuels such as petrl and cal, we prduce a gas called carbn dixide (CO2). T much f this gas pllutes the atmsphere, and causes it t keep in t much heat. As a result f the greenhuse effect, the Earth’s temperature is increasing. This causes sea level t rise, and in the future may cause cities t disappear.
Listen and read the article.
Cutting dwn frestsEvery year, we destry nature by cutting dwn huge areas f frests. This makes the greenhuse effect wrse because trees take in CO2 and prduce xygen. Cutting dwn trees als destrys the hmes f the animals that live in ur frests, and causes the surface f the sil t be easily destryed by rain. This can result in flds and even mre damage t the envirnment.Bad habitsMany f ur habits cause pllutin. Peple ften use things nce and then thrw them away, r leave them n the grund as litter. This creates muntains f rubbish and pllutes ur land and seas.

This means that we shuld nly buy and use prducts friendly t the envirnment. We shuld als recycle as many things as we can. We can reuse things fr the same purpse as befre, r we can use them fr new purpses. If we just learn t live in new and different ways, we can make a difference.
