Biodiversity refers to the presence of different species of plants, animals, reptiles, birds, etc over a particular piece of land. It includes every organism that’s living. Biodiversity is very important for maintaining the ecological balance of a place.

Significance of Biodiversity – Essay 1 (250 Words)
Biodiversity as the name itself suggests is the diversity in biology over a place. And the term biology includes everything that has been there naturally. It includes all the living species and organisms over an area.
Significance of Biodiversity
Biodiversity has the following significances as described below-
- Productive Significance
Biodiversity at a place produces many products with a good amount of value to humans. Different fruits, herbs and other products are used and sold by humans to sustain a living. It also contains several natural resources like water etc, which is very significant for animals and humans to sustain a living.
- Economical Significance
Biodiversity of a place provides bread and butter to a number of people. People like farmers and small traders are closely related to the biodiversity, they produce and trade the products offered by the biodiversity, to sustain their living.
- Ecological Significance
Biodiversity is very important for maintaining the ecological balance of a place. If the biodiversity of a place is disturbed so will be the ecology as all the species are interdependent. If a single species gets extinct for some reason, it is bound to make an impact on others.
Biodiversity is the heart of the planet and must be preserved as it is. Without biodiversity, there would be no life and almost all the species will extinct. Also it provides so many useful resources, necessary for survival. It is our utmost duty to preserve the biodiversity to ensure a safe future of the planet and its species.
Types of Biodiversity and Its Conservation – Essay 2 (400 Words)
Biodiversity refers to all the diverse life forms that exist on the planet. Though, the spread of biodiversity isn’t uniform throughout the planet and it is found in abundance in areas covered with dense forests. For example, biodiversity is found more in tropical areas than in other parts of the earth.
Types of Biodiversity
There are three types of biodiversity levels as described below-
- Genetic Diversity
Genetic diversity consists of all the various genes in all the animals, reptiles, plants, fungi, etc of the same species. Some of the importance of genetic diversity is species evolution, adaptive to changes in environmental conditions, good for agriculture productivity.
- Species Diversity
Species diversity accounts for the number of species over a specified area. The more variance of species resides in per unit area, the more is said to be the place’s species diversity.
- Ecosystem Diversity
Ecosystem diversity pertains to the diversity that exists between different ecosystems, habitats, and biological communities.
Biodiversity is threatened by habitat destruction, exploitation of resources, pollution, etc. It is therefore imperative that its conservation must begin with removing these obstacles. Biodiversity can only flourish if unnecessary and rampant destruction of forests is stopped; if people use the available resources sensibly; if pollution has been dealt with stern resolve. If these conditions are not met then it won’t be possible to conserve biodiversity.
However, the following measures can be taken for the conservation of biodiversity-
- Variety of plants, insects, animals, reptiles, etc. must be conserved in safe locations, just in case if they go extinct.
- Biodiversity rich areas should be declared as biodiversity reserves and human access should be allowed only for research purposes.
- Any kind of illegal trade of wildlife species, extinct or otherwise, should be highly restricted and punishable by law.
- All the natural resources – water, air, food, etc. should be adequately used and conserved as well.
- Pollution at all levels must be prevented and necessary steps to be taken to eliminate its effects on the biodiversity of the region.
Biodiversity is very essential for the existence of the ecological balance and its entire species. It is very important that it must be preserved at all costs with complete effort. If the biodiversity is not preserved then the day isn’t far away when its survival on the planet becomes so much difficult that it will become lifeless and dry.
Importance and Threats to Biodiversity – Essay 3 (500 – 600 Words)
Biodiversity, as the name indicates is the variety of life and species that exists on planet. All the species of plants, animals, reptiles, insects, aquatic life, etc, constitute the biodiversity of a particular place. Biodiversity isn’t uniformly distributed over the planet, and is found more in the forests and areas undisturbed by the humans.
Importance of Biodiversity
Each and every species found on the planet is important for the ecological balance of the planet. Every living species along with humans depend on each other.
If one species disappears or becomes extinct it affects the others as well. For example, birds play a vital role in preserving biodiversity. They feed on fruits, thereby resulting in scattering of seeds over the ground. This results in the growth of new plants and the cycle continues.
If the birds become extinct, the number of new plants germinating would be considerably less; therefore, affecting the biodiversity of the place. Also, humans also depend on biodiversity for their food supply, up to a large extent. Food, crop, fruits, underground water, etc all are the gifts of biodiversity to the human race. If the biodiversity is damaged then we will be left with no food and the planet will become lifeless and unlivable.
Threats to Biodiversity
The biodiversity today is threatened by several human activities. Some of the threats to biodiversity are listed below-
Encroachment into a forested area includes civil constructions of mammoth proportions for commercial purposes. Construction of buildings, houses, factories, etc, permanently destroys the biodiversity of the place. Biodiversity doesn’t stand a chance against the concrete construction and hence gets extinct.
- Agricultural Activities
Agricultural activities are another big threat to biodiversity. Agriculture industry is the fastest growing industry as the continuous rise in populations pushes the demand for food production. This, in turn, leads to encroachment of forests. The desired area is cleared for agriculture activities; therefore, resulting in loss of biodiversity.
- Roads and Railways
Construction of roads and railway lines through a forest area is very common and also one of the prime reasons for the loss of biodiversity. Both are big projects requiring clearing off a large area of forest land. Moreover, regular transport through these modes also disturbs the area’s biodiversity.
- Drain of Resources
In wake of increasing population rate that the world is witnessing today, the drain on our natural resources is inevitable. These natural resources are an integral part of biodiversity and play a vital role in its conservation. Any disturbance in the natural resources reserve is bound to give a blow to the biodiversity of that region. Like, humans can’t survive without natural resources so other species also can’t survive without them.
- Environmental Pollution
Environmental pollution is another serious threat to the biodiversity of a region. Pollution can come in many forms, water pollution, air pollution, soil pollution, etc all having its own causes and consequences. Pollution today has become the most immediate threat to the biodiversity and the life that it sustains. It threatens every form of life over the affected area. Also, pollution has become a global concern, threatening large biodiversity reserves on the planet. If the pollution isn’t contained effectively then it would be difficult to save the biodiversity.
Biodiversity is very important for life on the planet. In fact with its biodiversity reserves gone the planet would be nothing but a lifeless ball of dry and parched land. Every species in a biodiversity reserve is interdependent and if one gets extinct then sooner or later others too will follow. Therefore, all the biodiversity reserves must be protected at all costs by taking necessary steps.
