Hello GennyM: Yes... if one really stops & thinks about it... this world is a scary place.

My wife & I recycle everything we can too. But when I look around at all of the waste that is created by stores, manufacturers, restaurants, & all of us as individuals, etc. it just boggles my mind!

I can't imagine the world can go on like this for centuries to come.
I don't know as there is any way to argue against these kinds of obsessions.

The world is what it is. I think all most of us can do is to simply do what we can to address this sort of thing to the extent it occurs around us. For example, my wife & I have a dog we walk every day. We always pick up any litter we come upon along the way. We then dispose of it in a trash. Of course, in the end, the trash can gets emptied & the contents go to a trash collection center or perhaps to a landfill. So picking up the litter we pass on the street isn't a solution to the problem of global pollution. But it's something we can do.
Beyond that, I think we simply have to learn, as the Buddhist nun Pema Chödrön has written, to be "comfortable with uncertainly."
