What is biodiversity?


Biodiversity refers to the components of the earth’s biosphere. Bio means ‘life’, and diversity means variation. Therefore, the variation in the type and nature of living organisms in any specific area can be termed as biodiversity of that area. According to Wikipedia, biodiversity is the degree of variation of life. This can refer to genetic variation, species variation, or ecosystem variation within an area, biome, or planet.

Why is biodiversity important?

Everything that lives in an ecosystem is part of the web of life, including humans. Each species of vegetation and each creature has a place on the earth and plays a vital role in the circle of life. Plant, animal, and insect species interact and depend upon one another for what each offers, such as food, shelter, oxygen, and soil enrichment.

Maintaining a wide diversity of species in each ecosystem is necessary to preserve the web of life that sustains all living things. In his 1992 best-seller, "The Diversity of Life," famed Harvard University biologist Edward O. Wilson -- known as the "father of biodiversity," -- said, "It is reckless to suppose that biodiversity can be diminished indefinitely without threatening humanity itself."

Therefore, we should preserve our biodiversity for maintaining balance in nature, to not disturb the food chain, keep the life cycles, water cycles, and cycles of seasons in balanced state, etc. Similarly, we should preserve them so that our future generations can also get an opportunity to see/watch the different species of flora and fauna.

These points are explained below briefly:

Smooth running of Natural cycles and phenomena

Preserving biodiversity is vital to preserve the recycling power of nature. Nature recycles matters of earth; for instance, the composition of air. Oxygen breathed in by animals is replenished by the plants during photosynthesis. Similarly, the dead plants and animals are decomposed and become nutrients for newer plants; that is the death gives birth to newer lives. In the same fashion, the water is recycled by aquatic plants and animals as well as the phenomena like water cycles. If we don't take care of our biodiversity, these phenomena and cycles will be completely disturbed.

Saving flora and fauna for future generations

We need to save flora and fauna for our newer generations so that they will also be able to see them. Biodiversity constitutes of many explored and unexplored living organisms (both plants and animals). Conserving biodiversity will protect them so that their use and importance can be researched and used to for human causes. With the types of diseases and their occurrence increasing, the need for medicines is increasing too. By protecting the bio-diversity we can preserve the sources of many different medicines (herbs, animals, and minerals saved in the forest areas) which might be useful in future.

How can we conserve biodiversity?


Although the perspective on why conservation is necessary and other things differ vastly, the way to
conserve biodiversity are plainly straightforward. Afforestation, ban on poaching, creating safer environment for animals and so on are the sustainable ways to conserve biodiversity.

Afforestation

This is the simplest, multifaceted and sustainable way to conserve biodiversity and nature. Forest is the natural habitat of various plants and animals. Thus, increasing forest promotes and protects living organisms. Likewise, afforestation has many benefits including prevention of floods, landslides and soil erosion; maintaining balance in the nature; stabilizing weather conditions and climate, etc. All these make environment even more suitable for biosphere and will ultimately conserve them too.

Banning Poaching, Illegal hunting, etc.

Placing a ban on poaching and illegal hunting will reduce these activities. As a result, many animals which are in the verge of extinction because of uncontrolled hunting and poaching, can be saved. Legal protection to animals and plants provided by the government can be effective countrywide and can be introduced to specific plants and animals too, according to their population and growth rate.

Probable Questions for October/November 2015

(Image Credit: Unknown) A continuity to the Tradition: Like in the past, I am attempting to predict (so to say) questions that could show up in the upcoming October/November examination of 2015. Disclaimer First: These predictions are in no way scientific or really probable. Justification: However, these could be some topics you could brainstorm and practice upon, in order to prepare for your General Paper exams.

Consider the view that the key to good health is not medicine, but lifestyle

Image by Irina L from Pixabay "Health is a state of complete physical, mental and social wellbeing, not merely an absence of disease or infirmity." - World Health Organization. This definition of health in its broadest sense implies that curing of physical diseases and abnormalities alone cannot earn us a good health. Can medicines go beyond curing diseases, to improve our health on the mental and social grounds? The medicines for the mental diseases, like depression, might improve our mental and social health to some extent; however, good health in its broadest sense can only be achieved through improved lifestyle.

Probable Question for Oct/Nov 2012

Disclaimer Notice First First of all, I would like to share something with you: I have tried to guess probable questions like this for four sessions with this one being the latest and in my past guess-works, what I have experienced is that most of the students blindly rely on them and prepare only on the topic areas listed here. And when the questions do not fall from the areas I have listed there they simply show aggression. One person wrote in my Facebook Group in a satirical manner that, “100% questions were asked from my predicted topics.” Now, read an article on another blog. Ms Adrienne de Souza writes how students get tricked by reading probable questions. She frankly says that her predictions have been wrong before , like mine! And I've always included "a note of warning/disclaimer" in each of the earlier predictions.
