Hint: When the Wildlife Protection Act was implemented in the country, Indira Gandhi was the Prime Minister during that time. Also a census was conducted in this showed that the no. of tigers was reduced drastically in the country.
Complete step by step answer:
The Wildlife Protection Act was enacted by the Indian Parliament in 1972. This Act provides protection of the wildlife (flora and fauna) in the country. This act was enacted in order to ensure environmental and ecological security. During British rule, wildlife protection was considered a priority. Only after 1960, when many species of animals were on the edge of extinction, the issue became important. This act put up restrictions on activities like the hunting of different animal species. While talking about the Constitutional Provisions for the Wildlife Act, two Articles, Article 48A and 51A deal with it. Article 48A of the Constitution directs the Indian States to protect and improve the environment and wildlife Whereas Article 51A talks about the fundamental duties of the people of India. Their duty is to protect the natural environment including forests, wildlife, rivers, etc. Through this Act, wildlife advisory boards were formed, this act also helped India become a party to the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES). CITES is a multilateral treaty that aims to protect endangered animals and plants. The most significant feature of the Wildlife Protection Act was that it prohibited the hunting of endangered species.
So, the correct answer is Option C.
Note: As wildlife is a part of the forest, and before the law was passed forest came under the state subject. With the coming of the law, it now comes under the concurrent list. Also, there were only five national parks in India prior to the enactment of the act.
