I'm a big fan of contrails - those white lines of condensed water vapor that sometimes form in the wake of an aircraft. I love to see them criss-cross the blue sky. When we lived on Long Island I would sometimes go to the beach at Robert Moses State Park, spread my blanket on the sand, and watch the occasional sky writer making its mark in the summer sky.
It is human nature to want to make our mark - to leave something behind for folks to remember us by. Forest Witcraft wrote that "A hundred years from now it will not matter what my bank account was, the sort of house I lived in, or the kind of car I drove. But the world may be different because I was important in the life of a child".
So it is our influence on the next generation that will determine how we are remembered. The decisions we make today, individually and collectively, will pave the way. Each year when Earth Day rolls around, we are reminded that we can choose to conserve resources, recycle, and be stewards of the earth.
What message will we send across the generations? A hundred years from now, what kind of world will our progeny inherit?
