In this zone some engineers could be taking advantage of environmental features in their work, for example when building bridges across valleys, while others will want to counter the negative effects of natural disasters, of find ways to get resources without destroying the environment. How to protect water supplies from floods, designing earthquake proof buildings and taking renewable energy from the environment are all things engineers could be doing in this zone.
