Wise people in Massai

I think people in Massai are wise. We have to use new technology to forecast the weather, but they just only need to observe the stars. It let me think of our ancestors observed the weather and made the Lunar calendar. People in the old days are really smart. Instead of destroyed the environment to make their lives better, they follow the nature rules and still lived a comfortable life. Why don’t we keep this tradition to remain a balance between human and nature?
