5. What Can We Do ?
There are lots of ways we can help. We must keep water clean, and we must not waste it. Some charities are helping people to collect and store water. They are also building new dams, wells, and pumps, so that people can have clean water nearer their homes.
We must use non-renewable resources carefully, and we must not waste them. Scientists are investigating ways to use renewable resources, like sun, wind, and water, to make electricity so that we don´t need to use so many fossil fuels. We can also try to use less electricity.
