What are two ways people modify or change the environment?

People modify their environment in many ways:

By:

Hydroelectric power: moving water to create energy

Solar power: creating solar panels that convert the sun's rays into energy to heat homes.

Wind power: Using wind mills to capture the wind's energy, then converting it into energy we can use.

Geothermal energy:using heat inside the earth to create energy.

Biomass energy: burning organic matter(ex. corn) to create energy.
