I need to write an essay on why California is sinking.
What information shoul I include?
Farmers are often criticized for planting trees that are greedy to water and soil in that area.
This can also be the cause for California sinking.
Oil extraction in this region can also be the reason for California sinking.
However, pumping water back in the land will not be the solution in this case.
California valley is sinking mostly down to farmers that draw the water from the land. This causes less support for the ground that sinks.
Are you sure that California is sinking? I cannot find any evidence on this matter. Maybe you have misunderstood the task.
Tsunamis and other natural disasters are the main contributors. Landslides are also caused by the human effects that included carbon gases and the eroding soil.
