We spend a lot of time passing trees letting them go unnoticed. I think it is immensely beneficial to take some time and watch one for a while. Think about how it got there because we know it didn't get there by itself, and it can't walk. Maybe a bird dropped the nut or a squirrel forgot about the acorn it buried. Think about what it is made out of. It started from a seed of some sort, made of tree parts. Then it took in the rain, the sunshine, the earth, compost, and turned it into something majestic, making a tree out of non-tree elements. Think of what it has gone through, from seedling to sprout to tree, all the storms and attacks it must have endured while it grew. Now it provides a safe environment for all sorts of wildlife, whether they be insects, birds or squirrels or whoever else decides to nest in them, asking nothing in return. All the while it sucks in CO2 and pumps back out the oxygen that we breathe. Sometimes their roots even hold hills in place and prevent landslides from destroying our towns. It does all these things and asks for nothing in return, it simply stands there treeing to the benefit of all. I think the world would be a much better place if we learned to be more like the trees in our own way.
