Most of us are so used to having constant access to fresh and clean water that we take it for granted. While we need water to survive, we also waste a huge amount of it on things we don’t need. It’s estimated that the average American uses about 152 gallons (575 litres) of water a day, while the average European uses around 66 gallons (250 litres) of water. In comparison, people in developing countries have about 5 gallons (19 litres) to use every day – assuming they have any at all.

Many people don’t realize that water is a finite resource, and our supply is running out as the population is increasing. The United Nations has already warned us that five billion people could be affected by water shortages by 2050, so it’s crucial that we change the way we use water and find ways of cutting down our consumption.
