Green engineering focuses on creating a healthy living environment, protecting human health, and promoting sustainability. These engineers assist in the development of cost-effective and high-efficiency wind turbines and solar panels and they can work in any industry that requires the construction and powering of items. A green engineer can help almost any business, from agriculture to manufacturing to commercial development and real estate. Engineers that work in environmental engineering combine chemistry, biology, and soil science with engineering concepts to provide solutions to environmental challenges. There are no specific requirements for this field, in fact: many job listings require geotechnical or civil engineering degrees.

Environmental consultants guide issues such as waste management, recycling, flood danger, and climate change implications. To operate across a broad range of public and private enterprises, government sectors, and organizations, environmental consulting requires a diversified mix of skill sets, training, research and analytical experience, and regulatory expertise. Environmental science is one of the most prevalent educational backgrounds for environmental consultants. Many of the major scientific disciplines that are critical to environmental evaluations and analyses are covered in this topic, including chemistry, biology, geology, and physics.

Sustainable farming is also known as Sustainable agriculture is the use of farming practices that take into account ecological cycles. It's also sensitive to microbes and their interactions with the rest of the environment. To put it another way, sustainable farming promotes methods and practices that are economically feasible, environmentally sound, and preserve public health.
