Environmental biotechnology uses biotechnology techniques to address environmental problems caused by industrialization, pollution, and natural disasters. It involves techniques like bioremediation, which uses microbes to break down pollutants; bioplastics as a renewable alternative to plastics; biofuels as a cleaner energy source; and wastewater treatment using microbes. Environmental biotechnology aims to provide sustainable solutions to issues like pollution reduction, natural resource management, and waste treatment in a way that minimizes further environmental damage.
