The Problem
We throw 8,000,000 tonnes of plastic into the sea each year.
1) If we halve the amount of plastic we throw away each year…
a)How many tonnes would we be producing after ten years?
b)How long did it take us to get below 100,000 tonnes?
2) What if we quarter the amount of plastic we throw away each year?
Did you know?
Dolphins can weigh from 40.8 kg to more than 10 tonnes. The orca, or killer whale, is the world’s largest dolphin.
