Why did the giant mastodons and mammoths gradually disappear

It is not known for sure why they were extinct, many scientists believe that extinction was due to hunting, while other scientists believe that extinction was due to climate changes that destroyed the vegetation that these animals ate.

Explanation:

Mastodons and mammoths were animal-like elephants that inhabited the Earth in large groups, thousands of years ago. Scientists are not sure why mastodons and mammoths have disappeared. It may have been because of climate change in the environment in which they lived. Experts believe that the weather began to cool and thick ice sheets covered vast areas. This put an end to the pastures in which these animals lived and fed. On the other hand, other scientists agree that they were extinguished by the hunt made by the human being in search of meat.

the crusades are one of the most significant events in the history of europe and the middle east.   they were a series of religious wars carried out by christian crusaders from europe during the timeframe of the middle ages.   beginning in 1095 ce, the crusades saw european knights and noblemen travel to the middle east in an attempt to capture the holy land away from muslim people that had controlled the region for the previous centuries.   the term crusade means ‘cross’.   therefore, the europeans that became crusaders viewed themselves as ‘taking up the cross’.   in fact, many of the crusaders wore crosses on their clothing and armor as they made their pilgrimage to the holy land.
