Scientists from around the world are working on an unusual possibility. They are saying that one day it may be possible to grow plants on other planets. One of the key planets that scientists are looking at is Mars. They say that there is plenty of evidence that there was water on the planet.
Humans who may be sent to the planet will have to find their own resources to grow the crops. Water would be a huge factor in that. Another factor would be the soil available. One idea may be to grow soilless plants. This can be done and it may be the answer to a growing population on earth that needs more food. I guess we’ll see what happens.
