Rina8888 [55]

Answer:

Humans have destroyed and modified various locations, such as forests, jungles, oceans. They begin to modify an environment in order to build new infrastructures, like buildings, factories, or even communities.

Explanation:

The reason for this is because they want to get as much resources for economic purposes, like for example mines, touristic places, factories. At first, this interaction affects the environment more, because of the loss of species or resources due to the human activity. Then, after this, it will affect the human, because of the lack of resources and global contamination caused by the environment being destroyed or modified.
