Things people do can affect the environment but they can make choices to reduce their impacts. Societal activities have had major effects on the land, ocean, atmosphere, and even outer space. Students describe things society does to protect Earth’s resources and environments. Human activities have altered the biosphere, sometimes damaging it, although changes to environments can have different impacts for different living things. Activities and technologies can be engineered to reduce people’s impacts on Earth. Sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources, including the development of technologies and regulations.
