You paint a sad picture my friend. I listened to a podcast last year from a leading environmental scientist. His take is that the earth will suffer major catastrophes because of the way we are living but he had a great optimism to temper this. He pointed out that the worst of times brings out the best in people. We come together and join forces to find solutions. Whether that may be as your doing in contributing to picking up the mess, or whether that be people pulling together and pulling live bodies out of the rubble after an earthquake, a bomb blast or a tsunami, our hidden divinity seems to jump out in these moments. I think it's important not to give into a doomsday mindset, there's enough of that in some fundamental christian thought and I think only encourages learnt helplessness as an outcome.
Then why is it the best of times brings the worst out in people? On the average I pick up 30 to 50 plastic and glass bottles a day to recycle them, that ended up being garbage on the beach … This does include toilets, motorcycle parts, tires, chains connected to boat anchors, plastic bags and broken glass. What kind of environment is this to have any more people!!!
