2ways to minimize our impact on the biosphere and/or to minimize our footprint a clear understanding of why it is important to be aware of our impact on the planet

Reduce the use of fossil fuels, plant more trees and cut less trees down.

If we ignore the biosphere of the planet, global warming will increase, global temperatures will rise phenomenally and all living things (including humans) would die because they wouldn't be able to survive in the extreme temperatures.

Also limit oil spills in the ocean

To be honest i thinks its between the first answer and the third answer
