Environmental Engineering is a branch of engineering that focuses on protecting and improving the environment by designing, developing, and implementing solutions to environmental problems. It involves using principles from various scientific disciplines such as biology, chemistry, physics, soil science, hydrology, meteorology, and geology to develop sustainable technologies for pollution control, waste management, water supply, air quality, and natural resource management. Environmental engineers work in a wide range of settings including government agencies, consulting firms, industry, research institutions, and non-profit organizations to address environmental challenges such as climate change, water scarcity, and pollution control.
