Trees are pretty amazing things. However, due to their lack of thumbs or inability to purchase cell phones, it would seem impossible for trees to send texts. However, trees are unique in Sweden because they can do the impossible. Thanks to sensors installed in the trees, they can send texts when running out of water. These moisture sensors send out messages with details about the trees' moisture levels and their exact location.
These texts allow people who receive them to go out and ensure that their neighborhood trees are getting enough water—quite ingenious but also sort of scary.
