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 high level of biodiversity to keep the natural surroundings in a harmonious state. Here are some essays of varying length on Biodiversity to help you with the topic in your examination.
Essay on Biodiversity
Biodiversity Essay 1 (100 words)
Biodiversity, short for biological diversity, refers to the variety of different species of plants and animals living on Earth. It is important to maintain high level of biodiversity in order to ensure the smooth functioning of the environment and for the survival of mankind.
However, with the growing air, water and land pollution on our planet it is becoming difficult to maintain biodiversity. A number of species of plants and animals have become extinct as a fall-out of the rapid environmental changes caused due to the aforementioned reasons leading to decline in biodiversity. This needs to be controlled to save the planet and those living here.
Biodiversity Essay 2 (150 words)
Biodiversity is said to be a measure of different types of plants, animals and other organisms present in the ecosystem. All these contribute in maintaining a healthy environment on the planet and thus play an important role.
The various species of plants and animals present on Earth are not distributed evenly. The main reason for this uneven distribution is the climatic conditions of our planet. The climate varies highly in different parts of the world and thus there is a variation in the kind of life present in each part. The climatic conditions have undergone a major change over the last few decades and this has led to a decline in biodiversity. The growing imbalance can cause a threat to the mankind as well.
It is essential to ensure richness of biodiversity by controlling pollution and building an environment that is safe and secure for all the organisms living on the planet.
Biodiversity Essay 3 (200 words)
Biodiversity refers to the variability and variety of different species of plants and animals on Earth. This variety contributes towards making our planet inhabitable.
The reason for unequal distribution of various organisms in different parts of the world is the varied climatic conditions. There is greater terrestrial biodiversity near the equator and this is caused due to warm climate and high primary productivity. On the other hand marine biodiversity is highest along the coasts in the Western Pacific as it has the highest sea surface temperature. Biodiversity basically clusters in hotspots and while it has been on a rise through the time researchers state that it is likely to slow down in the times to come.
It is essential to maintain rich diversity to build a harmonious environment. It enables the survival of human beings by providing them their basic needs such food, shelter, medicines, etc. However, the increasing pollution which is continually degrading the environment is also having a negative impact on biodiversity. Several species that inhabited Earth earlier are now extinct and many other are feared to be extinct in the coming years. This will further lead to environmental imbalance and can prove to be hazardous for the human species.
Biodiversity Essay 4 (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, molluscs, crustaceans, etc. Our planet Earth was formed close to 4.54 billion years ago and there have been evidences 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 there by 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 the human beings to live in a harmonious state on Earth.
Biodiversity Essay 5 (300 words)
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 which is fit for the survival of the 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 a 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 further decline in biodiversity which in turn would lead to 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 grow more sensitive towards the 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 environment is nothing but paving way towards your own destruction. Do your bit to bring about the change!
Biodiversity Essay (400 words)
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 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. Richness of biodiversity makes our planet fit for the survival of each of the species living here.
However, unfortunately the 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 for the 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.
Essays on Climate Change
Global Warming Essay
One of the most pressing environmental issues today is the conservation of biodiversity. Many factors threaten the world's biological heritage. The challenge is for nations, government agencies, organisations and individuals to protect and enhance biological diversity, while continuing to meet people's needs for natural resources.
This challenge exists from local to global scales. If not met, future generations will live in a biologically impoverished world and perhaps one that is less capable of producing desired resources as well.
Conserving biological diversity involves restoring, protecting, conserving or enhancing the variety of life in an area so that the abundance and distribution of species and communities provide for continued existence and normal ecological functioning, including adaptation and extinction. Today our biosphere is in danger of extinction for a variety of reasons like lack of conservation in ecological planning; and destruction of natural habitats as space is given over to either alternative uses or is over-exploited and polluted. It is reported that during the next 20to30 years, the world would lose more than a million species of plants and animals-primarily because of environmental changes brought about by human beings. This demands an urgent attention for the conservation of biosphere.
The Global biodiversity assessment warns, "Unless actions are taken to protect biodiversity, we will lose forever the opportunity of reaping its full potential benefit to humankind." Effective and implementable methods of stopping further genetic erosion and fostering the rehabilitation of degraded ecosystems in mega biodiversity regions are the need of the hour. Efforts have been initiated to save biodiversity both by ex-situ and in-situ conservation.
This type of conservation includes conservation of plant and animals in their native ecosystems or in manmade ecosystem where they naturally occur.
This type of conservation applies only to wild fauna and flora and not to the domesticated animals and plants because conservation is possible by protection of population in nature.
In-situ conservation includes a system of protected areas of different categories, e.g., National Park, Sanctuaries, Biosphere Reserves, Cultural Landscapes, and National Monument etc. According to the World Conservation Union, protected area is defined as: "An area of land and/or sea specially dedicated to the protection and maintenance of biological diversity and of natural and associated cultural resources and managed through legal or other effective mean."
Ex-situ conservation means conservation of species (sample of genetic diversity), particularly of endangered species away from their natural habitat. It is done through establishment of 'gene banks', which include genetic resource centres, botanical gardens, cultural collection and zoos etc.
Wild Life Conservation in India
The shocking death of many tigers and lions due to a mysterious disease in our sanctuaries has brought wildlife conservation policies and their implementation into public focus. India has a wide variety of wildlife, many of them endangered, ranging from the snow leopard in the Himalayas to the giant Malabar squirrel in the rain forests of Kerala. Wildlife conservation has been very much in forefront of government policy and India is a signatory to the Convention on International Trade in Endangered Species (CITES).
Enforcement of wildlife protection is done under the Wildlife Protection Act, 1972. The Indian Board for Wildlife (IBWL) is the apex advisory body in the field of wildlife conservation in the country and is headed by the Prime Minister.
Indian wildlife is protected in 107 zoos, 49 deer parks, 16 safari parks, 6 snake parks, 24 breeding centres and 6 aquariums, besides of course 95 national parks and 500 sanctuaries. Forest staff looks after anti-poaching activities, habitat management and improvement. Besides, there are also projects for the flagship species like Project Tiger and Project Elephant where the habitats are maintained according to the requirements of the flagships species like tiger or elephant.
