Role of Biodiversity on this Planet!
Meaning, scope and importance of Biodiversity:
Bio means “life” and diversity means “differences”. The differences among the organisms are in food habits, and living habitats as well as morphological, anatomical, genetical, behavioural etc, and species, genus, order, family and phylum level are noted as Biodiversity. This diversity has to be maintained among the organisms (bacteria, plants and animals) for survival. The interrelationship among the organisms is conservable and protectable. Because, just imagine, if all the organisms’ food habits are the same, the food is not enough! If all the organisms live in the same habitat, the place is not enough! If the genetic makeup of all organisms is the same, only one species of organisms could have originated and lived on this planet! That is why we find various food chains, food webs and various species of organisms in all ecosystems.
How did all these diverse organisms evolve? Well, during evolutionary development, nature provided opportunities to organisms in a challenged environment with limited resources and competition. The organisms utilized the limited resources and adjusted and adapted in different directions. Yet, this diversity is very important among the organisms to continue the “life” on this earth. One may raise a question like ” What is the important organism on this planet?” Interestingly, we could say that all organisms are important due to their sensitive interrelationships and their ecological role. Extinction of one organism impacted badly on another organism either directly or indirectly, but bad is somehow compulsory. Now, the exploiting human population in the name of development such as industrialization, mechanization, and urbanization destroying “nature” with hazardous activities drastically such as global warming, acid rains, climate change, deforestation, ozone depletion and many more unnatural stupid initiations that have been diminishing the sensitive links among the diverse organisms irreversibly, knowingly and unknowingly. The man may forget the important thing as the human is also sitting somewhere in the food chain or food web of an ecosystem which flagged the disappearance of the human population on this green planet once, but compulsory!
