(a) The Sahara, the world’* largest desert, has some places which have something unbelievable about them e.g. there are places where it rains only about once a century or there are people who reach the end of their lives without even seeing water coming from the sky.
(b) Hippopotamuses are animals which need round the year water. The presence of these animals in Sahara tells us that it was green once. Beneath the Sahara, there are vast acquifiers of fresh water which is enough liquid to fill a small sea.
(c) There was an increased blast of sunlight during the summer months which caused *** Monsoon to shift to the North 10,000 years ago.
(d) Noone knows whether Sahara can ever change in the future. It is something scientists can ponder how human-driven climate change may alter the Sahara in the future.
(e) Jennifer Smith, a geologist at Washington University in St. Louis said that there was not much evidence of a paradise out there, but there was something perfectly liveable.
