The writers ask us to ‘imagine that the Earth isinside a kind of greenhouse with the atmospherearound it. The atmosphere acts like the glass: itlets sunlight in and keeps warmth from gettingout. The atmosphere is essential for all livingthings. Without it, the Earth would be as cold and lifeless as the surface of the moon’.
‘The trouble is that our atmosphere is changing because we are polluting it with chemicals—in the form of gases—and it is keeping in too much heat!’
These gases, mainly carbon dioxide (CO2), are produced by burning fuels such as petrol. The greenhouse effect may cause the level of the sea to rise and flood cities and even whole countries.123456 Read the second part of the review.
