What problem is caused when a trees are cut down faster then they can grow back ? how can this problem be fixed?

Deforestation is caused which means that they are being cleared faster than they can grow back.  this problem can be fixed if less growth would happen around forests, this problem could be fixed if there were to be more trees planted.

the effect of the ming leaders banning ships with more than two masts was that there was no further construction of ships masts, because there was a surplus. ming emperors disallowed foreign exploration

what are the choices btw if it was me id say the lack of money to continue with education
