Actually doing something as an individual is not difficult and not at all impossible.
I first experienced recycling in the 1950’s during my first non-family employment. The manufacturing firm would collect and recycle all the paper. They knew that 90% of all paper was used on only one side so they made scratch pads, etc out of the waste. I asked if they actually saved any money doing so as it seemed that the cost to sort etc would offset any sayings. I was told the actual savings approached 50%. Been recycling since.
Then personally I have been 100% off the electric grid for 9 years now and I use rainwater retention for 100% of my water needs for the past 6 years. My neighbors’ monthly utility bills have risen at least annually for both. At present, my ROI has come and gone and I am therefore actually saving more each month. In both cases, I have NEVER even felt the need to think about my usage. Never gave it a thought when neighbors lost power for a week when I provided a warm place to stay, showers, laundry and cooking for up to 10 guests at a time during that week. We never ran low on power nor did we need to conserve our water usage. Even on cloudy days, the solar field was generating some replacement power.
As for food, I did a complete gut of my original 1956 landscaping a few years ago. In doing so instead of ornamental planting around the house I used cranberry and blueberry bushes. The harvest went into my freezer. In the back yard, I planted 3 and 5 in 1 varieties of apples, cherries and plums the crop is then canned or frozen for use later. For fresh greens, etc a number of narrow raised beds along a walking path that rings the yard provide root crops, salad fixings, etc. What is the work this takes, why maybe 5 minutes to till up the soil and to spread seeds in the spring, I already have begun planting for this year. Those 5 minutes come as I take a break from my daily power stroll around the paths. Harvesting actually takes longer but even that is not more than an hour-long exercise per crop. So at 75, I get to do some physical and mental exercise in planning what to grow. Non of which takes much time. All on an under acre lot.
The net result is that I am saving far more than I spend for my more dependable resources, electricity and water, and healthier food.
Final thought, over the past few weeks, I have been reading many many articles about contaminated water. Using rainwater for all my needs takes that “fear” out of the picture for me as my tested water normally test out higher than that provided by the local utility.
Individually I don’t do a hell of a lot to mitigate my contributions to global warming, however, if more did similar all those little drops do add up.
Those poo, poo folks can now begin.
