Explain why world fresh water usage has increased to almost 4 trillion mega litres and why this is unsustainable.
The global population has increased.
Fresh water is being used in more and more ways. E.g. for mining, agriculture etc...
This is unsustainable because there will not be enough fresh water for everyone and existing fresh water is being contaminated.

What is the difference between a renewable and non-renewable resource and give an example of each.
Renewable resources do not run out. Paper would be an example of a renewable resource.
Non-renewable resources are finite which means they will run out one day. An example would be fossil fuels.
