When @wildwestnature posted that poem, I wrote it out onto a small piece of paper and put it where my eye falls to it often because it speaks to me on fears for the earth and I found reading it helpful.
I do not know what the answer to climate change is, but I do know that more people are thoughtful and considerate on a daily and ongoing basis than were when I was young. The ideas of hesitating before jumping on planes because of environmental impact or consolidating errands to minimize car use or considering how far your food had traveled did not even exist. I understand how for young people the situation might seem hopeless but for me, these seem harbingers of hope.
I do not subscribe to the “it makes no difference because I am only one person” school of thought but rather to the “how do you eat an elephant? one bite at a time,” so please do not be disabused that small steps are still steps. Sometimes just taking them and showing one can do so is enough to act as a model for others to want to replicate.
