97.5% of the world’s water is locked in seas and oceans, too salty for human use. And most of the remaining 2.5% is in the ice caps. So we humans depend on the tiny bit available as fresh water – an essential natural resource for life. But we don't just use water for drinking. We wash in it, clean with it, and use it to produce everything from clothing to food. Crop production – including feed for livestock and biofuels – is putting a great strain on fresh water supplies.
Water outdoor plants in the early morning or at the end of the day to stop water immediately evaporating in sunlight and heat. Water the soil so that the liquid goes straight to the roots, where it’s needed.
In a heatwave, animals need water too. Instead of watering your lawn, leave out a water-filled container, like a casserole dish, for birds to drink from and wash. Thirsty bees and other insects will need a saucer or bowl with water and stones in it.
Some companies and investors that buy up land around the world contribute to water scarcity and pollution. They sometimes deny local people access to water, pollute watercourses or exhaust supplies. This can affect the ability of local communities to farm and access safe drinking water.
