Why is Maintaining Biodiversity Important | 7 points

Biodiversity is the variation in the living animals on the earth.

It is interesting to see so many types of living beings in both plants and animals.

However, all of them are interdependent for survival.

We can see biodiversity in different habitats of environment like aquatic biodiversity, terrestrial biodiversity, soil biodiversity, etc. This diversity on the micro level can be attributed to chemical diversity, genetic diversity, functional diversity, etc. Also, there is diversity concerning gender (as male and female), age, size, etc.

This indicates that biodiversity is present in every aspect of life.

The importance of biodiversity in the environment comes from the fact that every living being including humans is dependent on it directly.

Any damage to it also affects humans at large. So we need to conserve biodiversity for our survival.

Why is maintaining biodiversity important

1. Provides stability. The air we breath is always fresh with sufficient oxygen. This oxygen ration is is kept in balance due to biodiversity. The plants produce the oxygen during photosynthesis by taking carbon dioxide. While humans and other animals breath in oxygen and leave out carbon-dioxide. This mutual dependence gives stability to life. Similarly plants consume nitrogen from soil to grow. The microbes decay the plant and its materials when dead to replace back the fertility back to soil.

In a forest number of herbivorous animals like goats, buffaloes, deer which grow their numbers by reproduction. They are being killed by wild animals like tigers, lions, hyenas etc for food. These animals if not killed will rise in their population exponentially. The biodiversity as carnivores and herbivores keeps check on their population.

3. Helps keep environment clean and healthy: Since ages there are many dead. These are decayed by bacteria to keep the environment clean. Or else this world would have been full of corpses. Similarly small animals like rats, insects, birds, pigs, dogs (stray) help to clear of waste around us. Hence we can see these living forms thriving in drainage canals, waste dumps indicating their role in environment.

4. Provides food to all the living beings: If you come across food chain in the nature, you will notice all the living beings are dependent on plants directly or indirectly. Carnivores depend on herbivores which in-turn depend on plants for survival.

Plants <—-small fish <—– Big fish <—– Shark.

5. Maintains health: Biodiversity is seen even in genetic diversity. There are also two types of genetic combinations during multiplication as mitosis and meiosis. In meiosis, we see two cells with a similar but distinct type of chromosomes getting merged. The out come of such combination is an offspring with better character than parents. Hence due to variation in genes, we develop more strong individuals. This is the reason we avoid marriage among blood relatives. Due to minimal genetic variation, there is chances of birth defects in children born.

6. Sustainability and growth. Due to gender differences, there is maintenance of population. The number of animals dead are replaced by the ones born. This is possible due to gender difference which leads for sexual reproduction. Without this gender biodiversity, reproduction would be impossible in higher animals. While in lower forms like bacteria and fungi even asexual reproduction is possible, still sexual reproduction helps the entertainment of the species for long. Also this reproduction is possible only after certain age. Thus growth and sustenance of species depends on biodiversity in terms of gender and age.

7. Adaptation to different habitats: Biodiversity enables living beings to adopt to different environments. Hence we can see aquatic animals have different set of respiration system suitable to breath in water. They cannot survive on earth as that respiration system does not support to breath air directly. Similarly, they can swim for long due to their modification of limbs in the form of fins.This adaptation is possible due to biological variation in them.

Humans tend to kill some or other elements of biodiversity by excess use of natural resources.

This, in turn, can be harmful to humans in the long run.

We need conserve the wildlife, soil and also prevent pollution to safe guard biodiversity.
