The term "water withdrawal" refers to the removal of fresh water from lakes, rivers, ponds, and groundwater pools for human use. In 1970, average global water withdrawal was below 1000 km³/year. Currently, average global water withdrawal exceeds 7,000 km³/year. Which trends most likely caused these changes in water withdrawal?
- Farming methods have changed such that they demand more access to water.
- Severe storms caused by climate change have provided an excess of water.
- Freshwater is used more sustainably now than it was in 1970.
