Biodiversity and the human implications
Biodiversity is the planet's full range of life forms. Humans are only one species among millions and biodiversity benefits humans and other species alike. Experts discuss why we need biodiversity. This includes food, medicines, industrial products, gene pool preservation, biological services such as pollination and cleaning water. We also have an ethical responsibility of stewardship over other species on the planet.
Students could be asked to identify the reasons the scientists interviewed in this clip give for preserving biodiversity. Some students could be asked to identify the reasons that the first scientist gives whilst others identify those listed by the second scientist. A class discussion on relative importance could follow.
