Why should biodiversity be conserved? Explain giving three reasons.
✓

Answer

Biodiversity should be conserved for the following reasons:
  1. The broadly utilitarian argument says that biodiversity plays a major role in many ecosystem services that nature provides.
  2. The narrow utilitarian argument says that humans derive countless direct economic benefits from nature and products of medicinal importance.
  3. 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.
