Nanotechnology has the ability to significantly improve the quality of our air, water, and energy generation, resulting in significant environmental impacts. Environmental nanotechnology is the use of nanotechnology techniques to mitigate or prevent environmental degradation. Nanotechnology can have an impact on our environment by offering solutions to clean up existing pollutants. Environmental nanotechnology has a lot of potential for improving our planet's quality of life. Nanotechnological materials, methods, and applications are predicted to make major contributions to environmental and climate protection by conserving raw resources, energy, and water, as well as lowering greenhouse gas emissions and hazardous waste. As a result, using nanomaterials offers some environmental benefits and sustainable impacts. Nanotechnology, on the other hand, is now playing a little part in environmental protection, whether in research or in real - time applications.
