abstract
After the existence of an organism, it strives hard to live in its surrounding environment. All the animals interact with its environment for energy gain and loss, to protect itself, and for all other activities. But in recent years world human population increased so fast that depleted the natural resources, degraded the environment and destroyed the habitat of animals. The main factors responsible for environmental degradation are land use, topography and population’s evolution. As a result wildlife species that are utilized for food and commercial purposes are going to decline or extinct. The wildlife that is the integral part of biodiversity can’t be saved until we tackle and solve the issues behind their extinction.
