Why were the miners who looked for gold in California called the 49rs?

because they all rushed to California during 1849.

Explanation:

during the California Gold Rush, people moved to California from across the country AND across the world. This movement began in 1849, hence the name "forty-niners"

life will not be easy it will be filled with war, lack of resources, damaged planet, and lack of land to live on.
