Wildlife plays a significant role in maintaining the ecological equilibrium of nature. The presence of wildlife affects the character of its habitat by continually supporting the evolutionary adaptations of everything in its environment. The presence of wildlife is also an effective way to assess the quality of the environment.
In developing countries in Africa and Asia, wildlife serves as an abundant resource of food and livelihood. The various plant species in the wild are also essential components of traditional medicine. In progressive nations, the presence of wildlife opens the possibility of a thriving tourism industry. National parks around the world earn massive incomes every year by opening wildlife observatories and creating safari parks where visitors can observe wild animals in their natural habitats.
