Question

The Industrial Revolution typically marks the beginning of humanity's environmental impact on our planet. But some scientists theorize that people began affecting the Earth thousands of years earlier. For example, the first ranchers burned forests and grasslands to create pastures for their grazing animals. Those new pastures reflected sunlight differently, possibly altering seasonal rainstorms. Ancient peoples who migrated to isolated islands brought invasive species that wiped out native plants and animals. Appreciating humanity's long history of habitat transformation will help scientists better understand an area's "natural state." It will also tell them whether it is possible, or even advisable, to restore the area to that state once more. Why does the passage include the detail about ancient people who migrated to isolated islands? 1 to highlight the impact humans have on even the most remote parts of the planet to explain that it is impossible to restore isolated islands to their natural state 3 to clarify that ancient peoples have had a more extensive impact on the environment than any other group 7​
