Only 0.3% of the world’s water is accessible and not all of that would be suitable for drinking water treatment, as some of it is in swamps or marshlands. As coastal erosion continues and sea levels rise, some of this fresh water may end up being engulfed or taken in by the ocean, as we lose land mass to the ocean. When this happens, we also lose available fresh water and land for people to live on. So I think that water scarcity will become an even bigger issue in the future than it is now. It’s important that we make decisions now to prevent these disasters in the future.
