The scoop: 40% of insect species are at risk of extinction.

Why it matters: We need bugs to survive and thrive.

  • Pollination: Pollinators pollinate plants; we need them to keep doing that.
  • Pest control: Paradoxically, predatory and parasitic insects kill pests.
  • Decomposition: Some insects are primary or secondary decomposers. They serve an important function to clean-up animal waste.
  • Food security: Many mammals, birds, reptiles and amphibians depend on bugs for food. They are a quick and easy resource for a nutritious meal.
  • Research and innovation: Technology mimics nature (think birds and planes). Researchers can observe the ethology of insects and learn new ways to innovate. An example? Ant colony optimization in computer science.

What's causing the insect decline: Habitat loss from agriculture and urbanization is the #1 driver. Agro-chemical pollutants (think pesticides), invasive species and climate change also play a role. You can check out some cool charts and figures below to learn more.

How to help: Contribute to the fight against pesticides, support or start a small farm, and educate others about the importance of insects. A more positive perception of 'bug people' can also lead to change.

Bottom line: We need bugs to survive, yet insect populations are on the decline. This issue deserves more recognition.
