We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some handy keywords to get your googling started:
Biodiversity - the variety of genes, species, and ecosystems
Conservation - ethical use and protection of valuable natural resources (e.g. trees, minerals, wildlife, water)
Ecosystem - a biological community of interacting organisms and their physical environment
Ecosystem services - benefits people obtain from ecosystems (four categories: supporting, provisioning, regulating, and cultural)
Richness - the number of species in an ecological community, landscape, or region
Pollinators - animals that help plants reproduce by moving pollen from male flowers to female flowers
Pollution - the introduction of contaminants into the natural environment (e.g. chemicals, particles, noise, heat, light)
