7
Q
What is sustainable development?
A
Taking enough resources to satisfy our needs but leaving more for the future, eg. fishing quotas so there is enough fish left to breed, or replanting woods.
8
Q
What does an increasing population mean for sustainable development?
A
It is crucial now because:
- Alternative energy supplies will be needed for when fossil fuels run out.
- Increasing food demands
- As more people will need more resources, sustainable development will ensure the survival of endangered species
