This would be The National Environmental Policy Act!
It was passed to protect the environment. Hope this helps!
The answer is A. Root crops, including yams, sweet potatoes, and taro, became more common.
The root crops became more common, and practically the basic food source. This was due to the fact that the climate and soil on the Pacific islands were excellent for growing them, and of course for having a sustainable food source.
The geography of a territory can impact the climate and atmosphere. Geology is the help of a territory. In the event that a zone is near a waterway it will in general make milder atmospheres. Precipitous regions will in general have increasingly extraordinary climate since it goes about as a hindrance to air developments and dampness.
