Document Summary
Arial view of crop fields circles are irrigated areas point is when we step back and look at a distance, we ve had a huge impact on a landscape scale. Has a lot to do with population growth and energy use. We see clear human impacts such as clear-cutting of tropical forests. 1860 industrial revolution population has double but energy use per person has increased even more. This is why we have such a huge effect on our earth. Major events over time not until recently that we ve had massive exponential growth. The projected numbers would be reached if our population grew by 2% per year. The number of people in the human population increased relatively slowly until. 1825, when the effects of the industrial revolution took hold, but since that time our. Don t expect to keep growing education/social economic factors decrease in (not population) but the growth rate.
