 We've come across some strange but incredibly helpful life forms. We didn't have to travel far to find them, but these organisms have proven invaluable on our trip through the solar system. They help feed us by nourishing and protecting our crops. They've built our soil structure to make it more resilient to the harsh weather we encounter. Our sensors indicate they're even helping us store carbon that plants take out of the atmosphere and put it back into the soil. Guess you can say our living and life-giving soil is the best thing to cling on to.
