Final answer:
US laws guarantee protection of biodiversity through the National Environmental Policy Act, Endangered Species Act, and other laws that broaden the role of biologists.
Step-by-step explanation:
The laws in the US that guarantee protection of biodiversity include three main parts:
- National Environmental Policy Act (1970): This law requires the analysis of environmental impacts in federal decision-making.
- Endangered Species Act (1973): This law calls for scientific involvement in the identification, protection, and recovery of threatened species.
- Marine Mammal Protection Act (1972), Clean Water Act (1972), Forest and Rangeland Renewable Resources Planning Act (1974), National Forest Management Act (1976), and Federal Land Policy Management Act (1976): These laws, among others, broaden the role of biologists in conservation and environmental protection.
