People have lived in the Sahara for thousands of years.The Tuareg people are famous desert travelers.They move from place to place with their camels.Today,the Sahara is facing new problems.Because of climate change,the desert is getting bigger.We need to work together to protect the land and the animals that call it home.

When a tree is attacked by insects,it can send a warning to other trees through the network.The other trees then produce chemicals(化学物质to protect themselves..For example,when a caterpillar (starts eating a tree's leaves,the tree can tell its neighbors to make their leaves taste bad. Trees also help each other.If a young tree does not get enough sunlight,older trees can send water and nutrients(to it through the network.In this way,the whole forest works as a big family. The discovery shows that trees are not just standing quietly.They are active and social.
