Lake Chad, Africa: A lost lake

Lake Chad used to be the third largest inland water body in Africa until sixties. Since then, the lake has shrunk by a whopping 95% due to a combination of agriculture and global warming. Delving further into the reasons would show that human activity and agriculture have been around the area long before the sixties. So, is human activity a significant reason why the lake is shrinking? reason yes, but not significant. That leaves us with one thing that has been a big debate for some time now; global warming. While newspaper and academicians don't seem to have a clear consensus on this issue, we do know that it is the human race that is causing lakes to dry up. I think it is time that we actually make an attempt at identifying the cause and work on correcting it.
