What is bio-diversity? Why is bio-diversity important for human lives?analyse. 5 marks

The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. Biodiversity includes not only species we consider rare, threatened, or endangered, but every living thing—even organisms we still know little about, such as microbes, fungi, and invertebrates. Biodiversity is important everywhere; species and habitats in your area as well as those in distant lands all play a role in maintaining healthy ecosystems. We need biodiversity to satisfy basic needs like food, drinking water, fuel, shelter, and medicine. Much of the world's population still uses plants and animals as a primary source of medicine, and in the United States alone, about 57% of the 150 most prescribed drugs have their origins in biodiversity. Ecosystems provide services such as pollination, seed dispersal, climate regulation, water purification, nutrient cycling, and control of agricultural pests. Many flowering plants depend on animals for pollination, and 30% of human crops depend on the free services of pollinators.

Bio-diversity:
Bio-diversity refers to the variety of plant and animal life in the world or in a particular habitat, a high level of which is usually considered to be important and desirable.

Importance of bio-diversity for human lives:
  • Bio-diversity is immensely rich in wildlife and cultivated species, diverse in form and function, but closely integrated in a system through multiple networks of interdependencies.
  • It is important for human lives because the human beings, along with the bio-diversity, form a complete web of ecological system in which we are only a part and are very much dependent on this system for our own existence.
  • Bio-diversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
  • For example, A larger number of plant species means a greater variety of crops.
  • Greater species diversity ensures natural sustainability for all life forms.
