How Do Humans Modify Their Environment?

Humans modify their environment in positive, neutral and negative ways to obtain what they want for daily life, both for necessities and prosperity. For example, people make changes to the land so that crops grow better, build buildings and other structures on the land, use disease resistant seeds and use pumps for obtaining well water.

Although humans may benefit from making such modifications to the environment, the physical environment can suffer when these modifications destroy the land or the habitat other animals and plants need to survive. Making streets wider, for example, requires the paving of land that may have grass on it, while using plant fertilizer can have negative effects on the health of the environment. Building a new shopping center can change the landforms, ecosystem and land cover in an area.
