The United Nations has proclaimed May 22 The International Day for Biological Diversity (IDB) to increase understanding and awareness of biodiversity issues. When first created by the Second Committee of the UN General Assembly in late 1993, 29 December (the date of entry into force of the Convention of Biological Diversity), was designated The International Day for Biological Diversity. In December 2000, the UN General Assembly adopted 22 May as IDB, to commemorate the adoption of the text of the Convention on 22 May 1992 by the Nairobi Final Act of the Conference for the Adoption of the Agreed Text of the Convention on Biological Diversity. This was partly done because it was difficult for many countries to plan and carry out suitable celebrations for the date of 29 December, given the number of holidays that coincide around that time of year.

History and Objective of International Day for Biological Diversity
1: Who was the first woman President of India?
The International Day for Biological Diversity was first established by the United Nations in 1993, following the adoption of the Convention on Biological Diversity (CBD) at the 1992 Earth Summit in Rio de Janeiro. Initially celebrated on December 29, the date was later changed to May 22 in 2000 to commemorate the adoption of the CBD text. The shift allowed for greater global participation and aligned the observance with broader environmental initiatives.
The main objective of this day is to raise awareness about the importance of biodiversity and promote actions to protect the planet’s natural wealth. It aims to highlight the vital role of biodiversity in sustaining life, supporting ecosystems, and contributing to food security, health, and sustainable development. The day also serves as a reminder of humanity’s responsibility to preserve nature for future generations. Through global campaigns and educational efforts, it encourages cooperation among individuals, communities, and governments to protect the Earth’s biological resources.

Start Learning!What is biological diversity?
The biological diversity is often known as a wide range of plants, livestock, and microorganisms, it also includes genetic differences within each species for example between crop and livestock varieties and the different ecosystems like lakes, forests, deserts, agricultural landscapes.
Resources for biological diversity are the pillars on which we build civilizations. Fish supply nearly 3 billion people with 20% of animal protein. Plants provide more than 80% of the human diet. In developing countries, up to 80 percent of people live in rural areas rely on traditional plant-based basic health care medicines.

When biodiversity has a problem, humanity has a problem
Biological diversity is commonly thought of in terms of the wide range of plants, animals, and microorganisms, but it also includes genetic differences within each species — for example, between crop varieties and livestock breeds — and the diversity of ecosystems (lakes, forests, deserts, and agricultural landscapes) that host a variety of interactions among their members (humans, plants, animals).
The cornerstones on which we build civilizations are biological diversity resources. About 3 billion individuals get 20% of their animal protein from fish. Plants account for more than 80% of the human diet. Traditional plant-based remedies are used by up to 80% of people living in rural areas in underdeveloped countries for basic healthcare.
However, the loss of biodiversity poses a threat to everyone, including our health. Biodiversity loss has been shown to increase zoonoses (diseases transmitted from animals to people), but biodiversity preservation provides good tools for fighting pandemics such as those caused by coronaviruses.
While there is a growing realization that biological diversity is a worldwide asset of enormous importance to future generations, certain human actions are reducing the number of species. The United Nations agreed to commemorate the International Day for Biological Diversity every year because of the importance of public education and awareness about this issue.

- “If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us” – David Suzuki
- “Either we leave our descendants an endowment of zero poverty, zero fossil-fuel use, and zero biodiversity loss, or we leave them facing a tax bill from Earth that could wipe them out” – Johan Rockstrom
- “This is the assembly of life that took a billion years to evolve. It has eaten the storms-folded them into its genes-and created the world that created us. It holds the world steady.” –
- “Biodiversity can’t be maintained by protecting a few species in a zoo, or by preserving greenbelts or national parks. To function properly, nature needs more room than that. It can maintain itself, however, without human expense, without zookeepers, park rangers, foresters or gene banks. All it needs is to be left alone.” – Donella Meadows

People can conserve water and reduce waste to help protect ecosystems. Supporting sustainable products and reducing plastic use also benefits biodiversity. Planting native trees and protecting wildlife habitats make a difference. Awareness and education promote responsible environmental actions.
What is the role of the Convention on Biological Diversity?
It is an international treaty to protect global biodiversity. The convention promotes sustainable use of natural resources. It encourages fair sharing of benefits from genetic resources. Nearly all countries in the world are parties to this treaty.
How does biodiversity affect climate change?
Healthy ecosystems absorb carbon dioxide, helping regulate the climate. Biodiversity loss weakens these natural climate buffers. Forests, wetlands, and oceans play major roles in carbon storage. Protecting biodiversity helps mitigate climate change effects.
Which ecosystems have the highest biodiversity?
Tropical rainforests have the richest variety of species. Coral reefs are also highly diverse marine ecosystems. Wetlands support many unique plants and animals. These ecosystems are critical for global biodiversity.
How does biodiversity benefit human health?
Many medicines come from plants and animals found in nature. Diverse ecosystems provide clean air and water essential for health. Biodiversity supports food security through crop and livestock variety. Loss of biodiversity can increase disease risks.
What are biodiversity hotspots?
Hotspots are regions with exceptional species richness and endemism. They face significant threats from human activity. Protecting these areas helps conserve many species at once. Examples include the Amazon Basin and Madagascar.
How do governments support biodiversity conservation?
Governments create protected areas like national parks and reserves. They enforce laws against poaching and habitat destruction. Many promote sustainable development and environmental education. International cooperation also strengthens conservation efforts.
