Answer:
1. Preserving natural resources such as farmland, parks, open spaces and unused land.
2. Design with Nature.
Step-by-step explanation:
Preserving the land keeps it as is. Thus, wildlife and animals aren't removed from their homes and are forced closer to cities and suburbs.
The way we occupy and modify the earth is best when it is planned and designed with careful regard to both the ecology and the character of the landscape.
