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.
Read the first part f the text and put the sentences belw in the right rder.

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.
