The “exchange” introduced a wide range of new calorically rich staple crops to the Old World namely potatoes, sweet potatoes, maize, and cassava. The primary benefit of the New World staples was that they could be grown in Old World climates that were unsuitable for the cultivation of Old World staples.
It was done for the protection of the community
Answer:
The government is doing their best to protect endangered species and one example of them is the Endangered Species Act. The Endangered Species Act (ESA) was enacted by Congress in 1973. Under the ESA, the federal government has the responsibility to protect endangered species (species that are likely to become extinct throughout all or a large portion of their range), threatened species (species that are likely to become endangered in the near future), and critical habitat (areas vital to the survival of endangered or threatened species). Once a species becomes listed in ESA's database as "threatened" or "endangered," it receives special protections by the federal government. Animals are protected from “take” and being traded or sold.
Explanation:
The primary goal of the Endangered Species Act is to make species' populations healthy and vital, so they can be delisted from the Endangered Species Act. Under the Endangered Species Act, the U.S. Fish & Wildlife Service oversees the listing and protection of all terrestrial animals and plants as well as freshwater fish. NOAA's National Marine Fisheries Service oversees marine fish and wildlife. The two organizations actively invest time and resources to help bring endangered or threatened species back from the brink of extinction.
