Abstract:

The environment encompasses all aspects of nature, both living and nonliving. The environment has an impact on the quality of life of plants and animals. Every living organism requires clean air, water, shelter, better living conditions, and a more ideal habitat because these factors influence one's quality of life. It is advantageous to have a safe and quality environment. Anthropogenic and natural activities have deteriorated the environment, resulting in climate change, pollution, and health issues worldwide. This review paper explored environmental issues experienced globally and in Nigeria through reviewing different works of literature. Findings show that man's activities on the environment include urbanization, deforestation, improper waste disposal, unregulated agricultural practices, among others, which have resulted in desertification, pollution, ocean acidification, health issues, global warming, and ecosystem instability. Environmental issues have a cyclical and spiral effect. One environmental problem can exacerbate another, hence the need for humans to be aware of the environmental issues. Man has a greater role to play in tackling environmental issues.
