The influence of anthropogenic factors is now intruded into every aspect of the environment. Emissions of chemical compounds into the air have greatly altered and modified the composition and energy balance of the atmosphere, thereby accelerating the pace of climate change. Additionally, the expansion of human activities into the natural landscapes, mostly manifested by urbanization and agriculture developments, has led to the reduction and fragmentation of wildlife habitats and loss of valuable Fauna and Flora. Furthermore, the discharge of industrial and agricultural runoff has contaminated rivers and streams, which severely disrupts the natural food-chain in the aquatic ecosystem and reduces the amount of freshwater, something that is indispensable for the survival of the species.
It seems that human beings, who are always regarding themselves as the dominant species because of their cleverness and inventiveness, are pushing the earth into a danger zone. Human-induced environmental issues are not new. The problem of deforestation, desertification, water pollution, climate change and the extinction of species have been present throughout the antiquity. However, with today’s advanced science and technology, people can do greater damages to the nature and do it more quickly. The impacts are further compounded. On the other hand, due to population growth, humans are prompted more than ever to exploit natural resources to meet the demands of the blooming population.
