Today it is completely over to you. How could you make your world a better place?
Go for a walk near your house. Do you see something that makes you feel sad? Is there rubbish on the ground? Has someone broken something at the park?
Isatou Ceesay saw the plastic bags in The Gambia and did something about it. What could you do?
Perhaps you could make a poster encouraging people to not drop litter.
Maybe you could write to the council to let them know about the broken swing.
Alternatively you could research and find out about some other world savers and changers, e.g. David Attenborough, Anita Roddick or Wangari Maathai. How have they inspired you to be a world saver?
