It includes all the living species and organisms over an area. 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. 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.
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. Biodiversity refers to all the diverse life forms that exist on the planet. For example, biodiversity is found more in tropical areas than in other parts of the earth. 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 accounts for the number of species over a specified area. 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.
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. 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. 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.
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. 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. 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.
Some examples are:. Pollution: Forests are destroyed due to air pollution and acid rain. Fish and other aquatic plants and animals die due to water pollution. Toxic and hazardous substances are discharged into the waterways, thus destroying aquatic life. Coastal birds, plants and other marine animals die due to oil spills in the sea. Wildlife gets trapped in plastic waste. It can be easily seen that pollution is a big threat to biodiversity. Population Growth and Poverty: More than six billion people live on Earth.
