Biodiversity refers to the importance of a wide variety of plants and animals that live in the world or in a specific habitat. It is important to maintain this level in order to balance the environmental harmony on our planet. Biodiversity, also referred to as biological diversity, is broadly the diversity or variability of different species of plants and animals on the Earth. It is essential to have a high level of biodiversity to keep the natural surroundings in a harmonious state.
Long and Short Essay on Biodiversity
Essay 1 (250 words)
Biodiversity, also referred to as biological diversity, is the variety of different species of flora and fauna living on Earth. The richer the biodiversity the more balanced and harmonious would the environment be. Different variety of plants and animals contribute their bit to make the planet worth inhabiting. One of the main reasons for the survival of human species on Earth is biodiversity. This is because various species of organisms help in meeting their basic needs of food, shelter, cloth and other resources.
There are around 300,000 species of flora that have been known to date and numerous species of fauna that includes not only animals but also birds, fish, reptiles, mammals, insects, mollusks, crustaceans, etc. Our planet Earth was formed close to 4.54 billion years ago and there has been evidence of life since around 3.5 billion years ago. A number of species of both flora and fauna have gone extinct over the past centuries and many more are anticipated to go extinct in the times to come thereby disturbing the level of biodiversity.
Human beings have become so driven towards technology over the years that they have forgotten its repercussions. Several new inventions have proven to be hazardous to the environment and are having a negative impact on biodiversity. It is high time humans should start taking the environmental issues seriously and contribute their bit towards improving the atmosphere. A healthy environment is essential for developing rich biodiversity which in turn is essential for human beings to live in a harmonious state on Earth.

Biodiversity is basically the measure of different plants, animals and other organisms living on earth. Each variety of flora and fauna present on Earth contributes its bit towards creating a balanced environment that is fit for the survival of living beings. These species help in fulfilling the basic survival needs of each other. It is thus important to have a rich biodiversity.
How has Biodiversity Declined?
While the importance of maintaining rich biodiversity has been stressed upon time and again, over the years the level of biodiversity has seen a downward trend and it is likely to go down further in the times to come. The main reason for this is the growing pollution which is an outcome of the industrial wastes and the use of various new-age inventions. Several species of plants and animals have become extinct in the recent past due to the environmental changes brought about by man and many are estimated to go extinct in the coming time. This would lead to a further decline in biodiversity which in turn would lead to an imbalance in the environment and cause a threat to the human race as well as other organisms living on Earth.
How to Add to Richness of Biodiversity?
It is essential to growing more sensitive to environmental concerns. The governments of various countries are spreading awareness about the same and are trying to curb the issue by using different means. It is also the responsibility of the common man to come forward to do his bit to conserve the environment.
Human beings seem to have grown so accustomed to using the technology that they have overlooked the importance of conserving the natural surroundings. It needs to be understood that insensitivity towards the environment is nothing but paving the way towards your own destruction. Do your bit to bring about the change!

Biodiversity, also referred to as Biological Diversity, is the variety of flora and fauna present in a particular habitat or on Earth as a whole. It has largely replaced the more clearly defined terms – species richness and species diversity.
Biodiversity – A Unified View of Biological Varieties
There are many other terms that have been used to define this diversity. These include ecological diversity (viewed from ecosystem diversity perspective), taxonomic diversity (gauged at the species diversity level), functional diversity (computation of the functionally disparate species within a population) and morphological diversity (derived from genetic diversity). Biodiversity offers a unified view of all these biological varieties.
Why is Biodiversity Important?
Biodiversity is important as it helps in maintaining a balance in the ecological system. Different plants and animals are interdependent on each other to get their basic needs fulfilled. For instance, human beings are dependent on various plants and animals for their food, shelter, and clothes and likewise, many other species are dependent on each other for such purposes. The richness of biodiversity makes our planet fit for the survival of each of the species living here.
However, unfortunately, growing pollution is having a negative impact on biodiversity. A number of plants and animals have gone extinct because of this and many are feared to become extinct in the times to come if the level of pollution continues to grow this way. This would result in a decline in biodiversity.
How to Maintain Biodiversity?
Human beings need to understand the importance of maintaining rich biodiversity. The vehicular smoke that leads to massive air pollution is becoming a threat to various species. This is one of the first things that need to be controlled in order to bring down the pollution level in the atmosphere. The industrial waste that goes into the sea is harmful to marine life and must thus be disposed of using some other means. Similarly, land and noise pollution must also be controlled.
Deforestation is also a major reason for the decline in the level of biodiversity. Not only is it rapidly bringing down the number of plants and trees but it is also taking away shelter from the animals and making it hard for them to survive. Such practices must be controlled in order to ensure harmony in the environment.
Every species of flora and fauna serves its unique purpose towards maintaining the environment and making it worth living. Thus, in order to maintain a balanced environment, it is important to maintain richness and balance of biodiversity.
