We shouldn't need to keep…

We shouldn't need to keep building outwards and into the greenbelt, we need to build upwards and into the spaces which have already been made available for housing! There is so much unused land outside of the greenbelt that is available, and if the owners are refusing to use it then it should be taken away from them. Public land should belong to the public, not some rich person or corporation who's just holding on to it until everything else is flooded.
We don't need more sprawl, we need smarter use of the land. The more we destroy our natural environment the more damage we'll incur because it isn't there to protect us. We need our green space, we need our farms, we need our forests, we need our wetlands, and we need nature!

Why are people allowed to buy land in the greenbelt anyway? That doesn't make any sense!
