Thirty-two years ago today, on December 29, 1993 (November 17, 1993 lunar calendar), the Convention on the Protection of Biological Diversity became international law. The Convention on the Protection of Biological Diversity, which emerged during the United Nations Conference on Environment and Development held in Rio de Janeiro, Brazil in June 1992, officially became a legally binding international law on December 29, 1993, thus providing a legal basis and policy guide for the protection of plants, animals and microorganisms in the field of environmental protection in the world and international cooperation. Biodiversity refers to the general term for the richness, diversity, variability and complexity of all living things (including various animals, plants and microorganisms) on the earth's land, waters and oceans, as well as the genetic genes they possess and the ecosystems they constitute. Biological species diversity actually includes three levels: species diversity, ecosystem diversity and genetic diversity. Biological species diversity provides basic conditions for human survival and development, and is considered to be the most important factor closely related to the sustainable development of human society. Most of the food, fuel, medicine, industrial and agricultural raw materials in people's daily lives come from biological resources, especially livestock, poultry, fruits and other economic plants that are domesticated and cultivated by their wild species. Environmentalists believe that there are at least 75,000 species of plants on earth that can be eaten by humans, but only 35,000 are currently used. Further use of plants by humans will help solve the world's food problem. Humans also need biodiversity to fight diseases. " The creation and emergence of the Convention on the Conservation of Biological Diversity (CBD) is a positive response to scientists' warnings about the state of the global species crisis more than a decade ago. Scientists point out that, mainly due to population growth and its related factors, the rate of global species decline has accelerated to 25,000 times the rate of survival of the fittest in nature. It is estimated that by 2050, half of the existing species on Earth will no longer exist. The core part of the Convention on the Conservation of Biological Diversity is 3 political principles: 1. Countries enjoy sovereignty in the development and utilization of resources while implementing environmental protection policies; 2. Relatively wealthy countries have an obligation to help relatively poor neighbors comply with the convention and should provide economic and technical assistance; 3. Species-rich but economically disadvantaged countries can share in the profits generated by manufactured products derived from their biological resources. The Convention on Biological Diversity has been signed by 167 countries around the world, but after governments sign the international treaty, it must be ratified by the legislatures of more than 30 countries before it can enter into force. In 1993, the number of countries that have ratified the convention reached 36, thus making it international law. As an obligation to the convention, signatories will develop strategies to protect plants, animals and microorganisms and their habitats within their borders, develop and implement laws to protect endangered species, expand natural reserves for biological species, work to restore damaged plant and animal populations, and raise public awareness of the need to protect nature and preserve living resources.
