Biodiversity means variety of lives in a certain environment, in an ecosystem one is made for another and it is important for sustainability.
There is always a problem in everywhere but there is also the solution. In the agriculture there are many problematic pests but there are also natural enemies, antagonistic lives. These things helps in the sustainable agricultural production. If the biodiversity is disturbed than the problems starts to arise, it means we have to use the foreign tools to manage the problems than the chemical used in the production increases the cost of production and poisoned foods.
Likewise, biodiversity is also have big role in water animals like fishes. When I was child I and my friend used to go for fishing nearby the ditches and wetlands. We used to catch many fishes but now due to the human activities like disturbing the water source by making roads, converted to the farm land and use of chemicals to catch the fish, now there is difficult to see the frogs too. Instantly we are not suffering from any kind of problems but I think the problem may arises in future. It clear impact is on those ethnic group who used to go for fishing for their livelihood and I think the impact also hits in the commercial ponds soon because they are nearby the farmland where many chemicals are used as agriculture inputs.
Forest ecosystem greatly impacts on farm. Nowadays the predator animals like tiger, lion are killed for their body part and the number of animals like deer, boar, porcupine etc. which destroy the crops are increasing. It’s difficult to control those animals by the farmers. Every years the wild animals destroy the tons of food.
Biodiversity should maintain for the food security and better nutrition.
