In the recent modern world, the danger of water shortange is getting more serious along with the environmental issues. This serious problem brings us quite a few critical challenges, for example, crops die, diseases spread, and eventually becomes an ultimate threat to human-beings. I believe the fundamental remedy for this is to improve the environment. On this account, even now, SNS and other mass media sometimes take up this issue, trying to highten people's awareness, however, I think there are a lot more that they can do to improve the situation.
