Question

why do we need to harvest water

Answer 1

water is a renewable resource but its scarcity is a major problem in various parts of the world

only 3% of the world water is pure and hence we should harvest water as much as possible so that we dont suffer from water scarcity

Answer 2

Mains water is a precious resource due to increases in demand from our ever growing population. Changes in rainfall patterns in the UK have seen both drought conditions and flooding. Rainwater harvesting can provide around 50 per cent of a family's water needs.
