CO2, NOx, plastics, all kinds of problematic chemicals - we all release more of those than we would strictly need to. And even the strict needs could be argued about, in some cases.
I am attempting (recently) to cut some chemicals and processed things from my house. Examples: using glass as much as I can, instead of plastic. Trying to use more local fresh ingredients in my cooking. Buying more from local stores rather than rely on the global supply chain. Trying and mostly failing to maintain a lawn (in suburbs) without some level of chemicals.
I know these are not all perfect examples.
Where things get tough is with time. It takes lots of time to re-engineer things down to simpler stricter needs. So, I still use grocery delivery, which generates a mountain of plastic, because I don't always have a span of time to get food I need.
