What I have Learnt
Something what can live for a long time is sustainable. Like the bridge that moves in London, it is sustainable because it moves a little bit with the wind so it will last longer than a normal bridge that the wind will break. We designed a sustainable stadium, mine was made of tin cans because they have been recycled.
Where you choose to live is a settlement. Dogland is under the water now but it used to be the best place to live in the stone age, because there were lots of fish, water and a mix of wet and hard land. It was good for people to live on because it had everything you needed. People who build with clay need to settle near water to make things with clay. A good settlement has soft and hard land, lots of animals, near water, maybe near mountains and with woods to build.
