Human activities in past decades have raised serious issues related to the environment and its conservation. Air pollution, poor management of waste, growing water scarcity, falling groundwater tables, water pollution, preservation and quality of forests, biodiversity loss, and land/soil degradation, global climate change, pollution, environmental degradation, resource depletion, and genetically modified foods are the current environmental problems that make us vulnerable to disasters and tragedies, now and in the future. For environmental issues including pollution of air and water, pollution related to heavy metals, and contamination of food, nanomaterials may be used as a promising and effective tool to overcome major challenges in the development of remediation methods that help in the protection of the environment. In this chapter, the essential aspects of environmental problems will be reviewed and then the application of new nanomaterials, which can serve as environmental cleaners, will be discussed.
