ABSTRACT
This chapter discusses the importance of a healthy environment and explores some factors affecting the environment. It explains the role of biotechnology in maintaining the planet and shows how the bioremediation helps clean wastewater. The chapter provides some environmentally friendly products such as biofuel, biodegradable plastic, oil-eating bacteria, biostimulation, bio leaching, vermitechnology, and biosorption. An ecosystem is a natural unit consisting of all plants, animals, and microorganisms in an area functioning together with all the nonliving physical factors of the environment. The living organisms are continually engaged in a highly interrelated set of relationships, with every other element constituting the environment in which they exist. The potential dangers of global warming are being increasingly studied by a wide global consortium of scientists, who are concerned about the potential long-term effects of global warming on our natural environment and on the earth in general.
