(iv) Humans are causing climate to change 170 times faster than natural forces.Human activities are impacting the climate system, which describes the causes and effects of human-induced climate change. The environmental impacts of human activity are expected to increase as the climate continues to warm and as the world becomes progressively more populated, industrialized, and urbanized. Soil erosion provides a prime example to understand what is at stake similar to oceans and landscape. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas into the atmosphere.
