Wildlife is a precious gift from God for this planet. The term "fauna" is not only for wild animals but also for all non-domesticated life forms including birds, insects, plants, fungi and even microscopic organisms. To maintain a healthy ecological balance on this land, animals, plants and marine species are as important as humans. Every organism on this earth has a unique place in the food chain that contributes to the ecosystem in its own way. But, unfortunately today, many animals and birds are endangered.
Natural habitats of animals and plants are destroyed for land development and agriculture by humans. Poaching and hunting of animals for fur, jewellery, meat and leather are other important factors contributing to the extinction of wildlife. If soon, no rigorous measures are taken to save the fauna, it would not be long when they find a place on the list of extinct species. And that would not be all! The extinction of wild species will certainly have a fatal impact on the human race. So, for us as human beings, it becomes a great responsibility to save the wildlife, our planet and, most importantly, ourselves. Here are some other reasons for deep understanding why wildlife plays such an important role in maintaining an ecological balance on Earth.
The ecosystem is entirely based on the relationships between different organisms linked by food webs and food chains. Even if a single wild species dies out of the ecosystem, it can disrupt the entire food chain and lead to disastrous results. Consider a simple example of a bee that is vital for the growth of some crops because of their pollen transport roles. If bees are reduced in number, the growth of food crops would decrease significantly due to lack of pollination.
Similarly, if a species becomes larger, it may again have a negative effect on the ecological balance. Consider another simple case of carnivores that is shrinking every day because of human poaching and hunting. The reduction of these carnivores leads to an increase in the number of herbivores that depend on forest vegetation for their survival. It would not be long, when the number of herbivores in the forests would rise to such an extent that they would move to farmland and villages for their food needs. Thus, saving wildlife plays a big role in controlling the ecological balance, maintaining a healthy ecosystem.
The human population depends largely on agricultural crops and plants for their food needs. Do you know that wildlife plays an important role in the growth of these crops? If not, we will understand the concept. The fruits and vegetables that we get from plants are the result of a process called pollination, a reproductive system in plants where the pollen grains of the male flower are transferred to the female flower, resulting in the production of seeds. Now, for pollination to occur, birds, bees and insects, some of the smallest species on this planet, play an important role. It is through these insects and birds that pollens are transferred between the flowers as they pass from one flower to another. Crop growth can be significantly affected if the number of birds and insects carried by the pollen decreases in number for any reason. You would be surprised to know that 90% of the world's apple production depends on the pollination of bees.
In addition to pollination, many birds also play an important role in pest control by feeding on them.
