John Muir is quoted as saying “When we try to pick out anything by itself, we find it hitched to everything else in the universe.”
Biodiversity is the sum of genes, species and ecosystems in a region. Because we live in cities, it's easy to forget how much we depend on the natural world. Our water comes from the tap, our food from the fridge, our environment is human-created. But we are biological creatures who depend on other species and ecosystems for us all to thrive. We're a part of nature and biodiversity is the basis of all our food and water. Here's a nice video by David Suzuki that explains why biodiversity matters.
