Homework: Problems from Maya Civilization

There are 3 problems now that Maya Civilization used to do.
First- an agriculture was a slash-and-burn system,which mean they also cut down trees in a forest and grow crops for their own,because this type of agriculture is not believed to be able to support tje high population densities of the Maya socities.

Second- a place that Mayan live are in drought time. Sometimes it's drought for a long time can grow anything for good.

Third-Also in a city of Maya, there is a bout 5 million people. That is a lot but it's in a small city.

I think a things could improve this is: to change a governement, need to find t he way to figure this out. Build more cities, raised more crop without use slash and burn system and try to save water for a drought time.
