Environmental law includes a wide range of issues pertaining to the use and protection of the natural environment, such as water and air quality, species protection, land management, and alternative energy sources. Environmental attorneys work for private firms or government agencies and handle cases within these areas. As an environmental attorney, you need to follow all rules and regulations that may affect your company or the government agency you work for. Sustainability is a growing field, with new legislation being regularly produced, so the demand for environmental attorneys is expected to increase.
