You may have seen projections of how the world could look in the future if climate change continues to get worse. These maps often show large parts of the world submerged underwater. Perhaps things won't ever get as bad as that. Or perhaps we'll have to learn to live with — or even on — water. In some places, they're already doing exactly that. The Netherlands is one of those places. And there's a good reason for it — about one-third of the country is below sea level. More and more Dutch people are embracing floating homes. They've already got the world's largest floating office building, as well as a floating farm. Of course, living on water isn't new. People in flood-prone areas have been building their houses on stilts for ages. And then there are the many people around the world who live on boats. But modern technology is helping to make floating houses more closely resemble the land homes people are used to. According to the Yale School of the Environment, these houses often rest on steel poles and "are usually connected to the local sewer system and power grid." It adds that they are "structurally similar to houses built on land," but have a heavy concrete "hull" underneath that helps them stay stable. They rise when the water rises and fall when it falls. They may not be for everyone. Some residents say the buildings don't just rise and fall — they rock. They're also a little more difficult to connect to power grids and sewers. However, they do solve some problems for city planners. Cities are under pressure for space, and floating buildings allow communities to expand in a new way. And it's not only the Netherlands that's embracing the idea. These types of homes are also being built in some of the island nations that are most at risk of sea-level rise caused by climate change. This could be just one of the ways we adapt to a watery future — which might arrive sooner than we think.
