What effect do you have on the Earth system? As a part of the biosphere, think of some ways that you change the atmosphere, hydrosphere, or geosphere.

Explanation:

As part of the biosphere, all living organisms on the earth interact and changes the other spheres in one way or the other.

Here are some of the ways we change the other spheres:

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.
