As you know, we are in a dificuld situation: the Earth's temperature is going up.

But that is not just a political problem, it is also our fault, for

example, when we use cars, motorbikes, buses . . . we pollute the air too.

Politician, of course, have a part of the fault, because they make money

selling oils and fuels.

But now, talk about what do we must do, mustn't and can do:

WE MUST:

• Turn down the heating in winter and wear more clothes if we are cold
• Turn the air conditioning in summer or use a fan

WE MUSTN'T:

• Use plastic bags when we go to the shop
• Use the car if we can go walking

WE CAN:

• Don't use the own transport if we can use the public transport
• Recycle, reduce and reuse
