Hello

1. Pollution in cities will get worse if we don't take measures for traffics.

2. People will get sick if they are exposed to hazardous chemicals and pollutants in the air and water.

3. Solar energy will be in great demand when non-renewable energy sources become scarce and more expensive.

4. London will be flooded if sea levels continue to rise.

5. You will save a lot of money if you buy light low-energy light bubs.

Pour rappel, if exprime une condition.

Have a nice day !
