using large amounts of natural resources

Explanation:

Carrying capacity of the environment can be defined as the optimal (maximum acceptable) level of use that an area can receive with a high level of satisfaction for users (visitors, researchers, employees) and minimal negative effects on resources. To some extent, the carrying capacity of the environment can be increased through agriculture, animal taming and the use of language. However, as a requirement to increase the carrying capacity of the environment is to engage in activity that does not adversely affect the area's resources, it is not possible to increase the carrying capacity of the environment by using large amounts of natural resources.
