give us ideas of how can we change our planet.
This week we´re talking about a world without petrol. Can you count how many things would dissapeared if petrol finish its existence?
we can think: " it will be in many years" or "it doesn't matter, I don't use so many things with petrol".
Not only cars use petrol, pens, chairs, washing machines and also some food contain petrol.
We must do something, The world is in our hands.
What do you think?
