Biodiversity is defined as the variability among living organisms from all sources, including diversity within and between species and ecosystems. It is important because it provides us with ecosystem services like food and medicine, it supports economies and livelihoods, and it improves resilience to environmental change. However, biodiversity is being lost at an alarming rate due to factors like habitat loss, climate change, and invasive species, threatening these benefits that biodiversity provides.
