The human population of the world is growing rapidly and standards of living are rising. Why does this reduce biodiversity?
More carbon dioxide is breathed out by the respiring human population
More raw materials are used up and more waste is produced by humans
More new species evolve to make use of the habitats that humans create
More energy is transferred between the trophic levels in a food chain
