The correct answer is: A. 1997
1997 was the International Year of Biodiversity. It was proclaimed by the United Nations General Assembly in December 1993. The year was dedicated to promoting understanding and awareness of biodiversity and its importance for human well-being.
Biodiversity is the variety of life on Earth. It includes the variety of plants, animals, fungi, and microorganisms, as well as the variety of ecosystems in which they live. Biodiversity is essential for human well-being. It provides us with food, water, medicine, and other resources. It also helps to regulate the climate and protect us from natural disasters.
The International Year of Biodiversity was a success in raising awareness of the importance of biodiversity. It led to the adoption of the Convention on Biological Diversity, which is an international treaty that aims to conserve biodiversity, promote its sustainable use, and share the benefits arising from the use of genetic resources.
The year also led to the development of a number of national and international initiatives to conserve biodiversity. These initiatives include the establishment of protected areas, the development of sustainable agriculture practices, and the promotion of public education about biodiversity.
The International Year of Biodiversity was a landmark event in the history of conservation. It helped to put biodiversity on the global agenda and led to a number of important initiatives to protect it.
