Question

protecting endangered species
endangered species are animals or plants that have been classified as being in danger of extinction. one of the first
elief\ measures to protect endangered species was taken in 1973 at a conference of 80 concerned nations. at the conference, the nations signed the convention on international trade in endangered species of wild flora and fauna, agreeing to stop imports of endangered species, such as ivory from african elephants. by 2001, more than 150 nations had signed the convention.
in 1973, the u. s. congress passed the endangered species act, which was written to protect vital habitats of endangered species. it has been extended many times, but it has many opponents in industry and special interest groups.
national park systems and national heritage lands throughout the world offer protection for threatened or endangered species. many parks include research stations that replenish breeding stocks and study the balances in ecosystems. for example, some parks do not allow any wildlife collecting or hunting, but they do allow some logging. independent research foundations and nature conservancy foundations purchase land to set aside for use by endangered species. all these measures are only small steps toward saving endangered species and preserving the diversity of life on our planet.

evaluation on the lines provided, answer the following questions.

1. explain why national parks cannot completely protect endangered species.
2. why is international cooperation vital for saving endangered species?

Explanation:

1. The text states that national parks often have mixed - use systems. For example, some allow logging even if they restrict wildlife collecting or hunting. This shows that they cannot fully protect endangered species as human activities (like logging) still occur within them.
2. Endangered species are a global issue. Different countries have different endangered species. International cooperation (like the Convention on International Trade in Endangered Species) is needed to stop illegal trade (e.g., ivory from African elephants which are endangered). Also, sharing knowledge and resources across countries helps in better conservation efforts as no single country can handle all the world's endangered species alone.

Answer:

1. National parks often have mixed - use systems. For example, some allow logging while restricting wildlife collecting or hunting.
2. Endangered species are a global issue. International cooperation stops illegal trade (e.g., ivory) and allows sharing of knowledge and resources for better conservation as no single country can handle all endangered species alone.
