Grocery Bags and Space Junk

I have had it up to my eyeballs with talk about banning grocery bags. Yes, I am for a clean environment but grocery bags!? I save all my plastic bags I get from the store and fold them and use them and re-use them again if I can. I even bring my lunch to work in them. I do not buy plastic bags in any size or shape which can be tricky if you have plants in your yard to trim but it can be done.
Now I love those disaster movies that show how we pollute the environment and help to speed up global warming. I like the special effects and how Hollywood likes to destroy national monuments. For me, the bigger lesson from these movies and science in general is that automobile and factory emissions are what damage the environment more than bags. I have seen the data about the grocery bags and the horrid pictures of the poor sea creatures that suffer, but in my opinion that is due to people who are careless and litter. I have seen so many people shamelessly throw trash in any spot! I am constantly picking up trash, sweeping, cleaning, to keep my small areas I inhabit here on Earth clean. I recycle, I ride my bike to work, walk to pay my bills. I use my car only once in a while if I have to go grocery shopping and I love my plastic bags. If we ban plastic bags, then we need to ban ALL bags that are plastic, reduce the amount of packaging used to sell and promote products, and all around simplify our lives in order to not use up so many precious natural resources required to make these packages.
We even have litter orbiting the planet! I read an article years ago on Space.com about the JUNK orbiting the Earth and the risk it poses to astronauts, satellites, and Earth.
I think that instead of focusing only on plastic bags (because in my jaded opinion I think grocery stores want to save money), we should all walk, skate, ride, or use public transportation, buy products with less packaging, and do not litter, especially at the beach.
I think that will save us money, protect resources, and could improve our health all at the same time.
