Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Human activities don’t have any effect on Earth systems.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The burning of fossil fuels and the growth of animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. In turn, this drives climate change.

Detailed explanation-2: -Humans affect the Earth system through processes like generating emissions and altering the land surface for agriculture or urbanization. Correspondingly, changes in the Earth system, including increases in temperatures and extreme weather events, affect human systems like our ability to produce energy and agriculture.

Detailed explanation-3: -Human activities now cause land erosion and soil movement annually that exceed all natural processes. Air and water pollution caused by human activities affect the condition of the atmosphere and of rivers and lakes, with damaging effects on other species and on human health.

Detailed explanation-4: -The impacts of intensive land use can cause compaction, erosion and the loss of soil carbon. This can reduce the biodiversity of soil, its health and productivity. Most human-caused erosion is due to pastoral farming. Soil from forestry land can also be eroded when forests are cut down and replanted.

Detailed explanation-5: -Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
