Class 12 Biology Biodiversity and Conservation Biodiversity conservation

Biodiversity conservation

  • Reasons of conserving biodiversity is grouped into three categories

             narrowly utilitarian

             broadly utilitarian

             Ethical.

  • Narrowly utilitarian- humans derive countless direct economic benefits from nature such as cereals, pulses, fruits, firewood, fiber, construction material, industrial products like tannins, lubricants, dyes, resins, and perfumes.

  • broadly utilitarian-
  • Biodiversity plays a major role in many ecosystem services that nature provides.
  • Amazon forest is estimated to produce, through photosynthesis, 20 per cent of the total oxygen in the earth’s atmosphere
  • Bees, bumblebees, birds and bats pollinate the flowers without which plants cannot give us fruits or seeds.

  • The ethical argument for conserving biodiversity relates to what we owe to millions of plant, animal and microbe species with whom we share this planet.
