All plant and animal species are inter-connected and depend upon one another, forming a web of life. These connections create a more biologically diverse world able to protect itself from damage, such as viruses and wildfires. Disruptions to these connections, however, reduce biodiversity and threaten human health, livelihood and survival. Population growth, pesticide use, monoculture farming and gardening, and climate change are such disruptions. In the last 40 years alone, the number of mammals, birds, reptiles, amphibians and fish worldwide has decreased in half. There are a number of ways, though, that you can help protect biodiversity – through reducing your use and the agricultural use of pesticides, changing your consumption habits, and advocating knowledgeably to the right people about the need for change.
