How to end hunger and create more land.

We need to create more land development underground and with Stargates we can tap into dimensions to get food and extra resources. It requires much stability and is dangerous you may get stuck never able to return. We also don't know what happen when it closes. If we could develop dimensional teleportation we bring objects here and create many new things. We also don't understand how dangerous going through and back could be. We may have to wear dimensional suits. We could also create teleportation by programming in the same universe we may be able to travel within our universe. Especially following portal principles from Heaven we may be able to create new technology. On Earth we look at these things with consideration. One thing we have to account for is safety of yawn principles where objects come through too. We may be able to control subspace too with that.
