Importance of Biodiversity: Human Health, Economy, and Climate

Study Notes

Biodiversity: Essential for People and Planet

Biodiversity is the multitude of living species that make up life on Earth, including plants, animals, fungi, and bacteria, as well as the ecosystems they inhabit, such as forests, oceans, and coral reefs. It is the foundation of most industries and livelihoods, ensuring fertile soil and a variety of foods, including fruits and vegetables, and helping to regulate climate through carbon storage. Biodiversity also plays a crucial role in human health, protecting against the spread of diseases and serving as a source of many drugs used in modern medicine.

Biodiversity and Human Health

Biodiversity is essential for human health in several ways. Healthy ecosystems can protect against the spread of diseases by maintaining a balance of species that can lower infection rates for zoonotic diseases. For instance, in the United States, at least 118 of the top 150 prescription drugs are based on natural sources. Moreover, about 70% of cancer drugs are either natural products or synthetic ones inspired by nature.

Biodiversity and the Economy

Biodiversity underpins economic prosperity, contributing to industries such as agriculture, food and beverages, and construction, which are heavily dependent on nature. Roughly US$44 trillion of economic value generation is moderately or highly dependent on nature, representing more than half of global GDP. In addition to direct resource extraction from forests and oceans, industries rely on ecosystem services such as clean water, pollination, and a stable climate.

Biodiversity and the Climate Crisis

Biodiversity is crucial in tackling the climate crisis, as land and oceans serve as natural carbon sinks, absorbing more than half of all greenhouse gas emissions. Conserving and restoring natural spaces on land and in water is necessary for limiting carbon emissions and providing one-third of the mitigation effort needed in the next decade. Ecosystems also act as buffers against extreme weather, protecting houses, crops, water supplies, and vital infrastructure.

In conclusion, biodiversity is essential for the health and well-being of people and the planet. It is crucial for maintaining a healthy environment, ensuring food security, and supporting various industries. As the world faces an unprecedented biodiversity loss crisis, it is crucial that governments, organizations, and individuals work together to conserve and protect biodiversity for future generations.
