The importance of biodiversity

Why is biodiversity important? First of all, biodiversity supports such diverse activities as agriculture, horticulture, selective breeding, pharmaceuticals, cosmetics, pulp and paper, water purification and waste treatment. Most recently, the value of biodiversity to climate moderation and ecosystem resilience is receiving much attention. We are only beginning to realize the ways in which biodiversity will impact and be impacted by climate change. In short, human life depends on biodiversity.

A few of the more studied values or benefits of biodiversity include:

  • Purification of air and water
  • Soil fertility
  • Food, fuel, and fiber
  • Stabilization and moderation of climate
  • Moderation of floods, droughts, temperature extremes, and forces of wind
  • Control of pests and disease
  • Genetic resources for crop varieties, animal breeds, medicines
  • Pollination of plants, including 95% of the world's crops

Building a Biodiversity Calendar

Each year special days and weeks are celebrated to raise awareness about the importance of biodiversity. We can build a calendar around these spotlights.

  • Earth Day is April 22. Earth Day Network's year-round mission is to broaden, diversify and activate the environmental movement worldwide, through a combination of education, public policy, and consumer campaigns.
  • Endangered Species Day. On May 15, 2015, the Fish and Wildlife Service observed Endangered Species Day in order to recognize the national conservation effort to protect our nation’s endangered species and their habitats.
  • International Migratory Bird Day, in May. Each year celebrates a different theme. "Birds Connect our World" is the IMBD 2020 theme, which focuses on the tracking technologies used to explore the routes of migratory birds across the globe, and how this knowledge is used to inform conservation. See to learn more.
  • National Pollinator Week is June 22-28 in 2020. Pollinating animals, including bees, birds, butterflies, bats, beetles and others, are vital to our delicate ecosystem, supporting terrestrial wildlife, providing healthy watersheds, and more. provides information and free materials each year to bring awareness to this critically important topic. And of course be sure to visit our pollinator page for lots of great info and references.
