Officials are looking to combat the drought, saying it was looking more likely that it will have to turn off most taps on "Day Zero," or April 21 stating that 60 percent of residents are "callously" using more than the current limit and that the city will fine households that use too much water.

There are more than 7 billion of us living on planet Earth today. By 2050, it’s going to get more crowded. The population is expected to increase to about 10 billion. Projections say farmers will have to boost food output by up to 100 percent. But scarcity is already an issue. Cape Town, South Africa is expected to run out of water in April.
