Imagine a person actually thinking thay are combating global warming by using a multi use grocery bag. Its laughable if not sad.

To actually make a dent in the exponential change in climate would require government and individual spending on infrastructure that ( I estimate) is many times an individual or corporate annual income. Who do you know that would make that sacrifice? Even if successful things will get worse before it gets better in the midst of all the sacrifice.

While we are clever, Humans may value comfort over the cost of changing our ways. I doubt we will choose cost over comfort.
