Environmental Effects of the Fossil Fuel Age
By John McNeill
Over the last two centuries, human activity has transformed the chemistry of
Earth’s water and air, altered the face of Earth ...
recently, with the harnessing of fossil fuels, has humankind acquired the
power to effect thorough changes on air, water, soils, plants, and animals.
Armed with fossil fuels, people have changed ... been able to bring about
environmental change much more rapidly, through acceleration of old
activities such as deforestation.
