Humans and the Environment: Positive Impacts
Subjects / Biology / Living Organisms And Their Environment
This title looks at how humans can have a positive impact on the environment. Farmers have a choice. They can farm intensively, or they can opt for the more environmentally friendly approach of organic farming. The first chapter in this title will focus on what organic farming means, on the different methods that organic farmers use, and on how they affect the surrounding environment less than the conventional methods used by intensive farmers. The second chapter will look at what we mean by sustainability. Many choices affect the planet - whether they are made at a local, a national or a global level. We must make sure that these choices do not impact negatively on the environment, so that future generations can continue to enjoy the resources and the huge biodiversity of life that the Earth provides.
