We could at least try and it might delay the inevitable. I'll give you credit in that you at least see there is a problem.
I would be happy to use alternate fuels. Fuel cells, bio diesel, higher alcohol content in our gasoline. The nation wold never have to import a gallon of oil again and slowly be weaned from resources that will become scarce.
Nuclear power is okay for aircraft carriers and submarines moving in our oceans, but not okay to power our cities? That is bizarre to me. We are going to need something if more people want to charge an electric vehicle overnight to get to work in the morning.
I don't agree with AOC that we will be dead in 10-11 years. I also don't blame the US for causing a worldwide problem. I have spent time in the ugly industrial cities in China. These are the places tourists don't visit. Residents wear masks when they go outside. There were ashes sticking to my hotel window on the 15th floor and I couldn't see the mountains in the distance until the early afternoon. There is not a city in the US that has this issue today.
We have converted too many acres of farmlands into large structures like new Walmarts only to leave the old buildings vacant. We build a new strip mall on green fields while the one nearby is only 50% occupied. We build holding ponds (instead of preserving a grass or wooded field) to control flooding after paving land that once absorbed rain water.
We have pushed farmers out for new subdivisions and forced them to feed the world and grow crops for fuel on less land. Farmers have cleared wooded areas to increase their acreage with a loss of natures best machines (trees) to convert CO2 to O2. Look at the cities we live in and how many fields with grass and trees have been lost in the last 40-50 years. Those fields absorbed ground water and aided the trees in converting CO2 to O2.
Cities in England cities are crowded and they build up instead of out. The countryside is more untouched and not littered with billboards. There is something to learn from this.
While our cars are cleaner and more efficient than ever, we have been destroying natures best defenses. Ask someone that has lived in your city for 50 years. Ask them where the city ended and the rural area began 50 years ago. Nature has cleaned up worse environments over the last millions of years than we have now. It isn't just what we are putting into the environment, it is what we have done that makes it more challenging for nature to clean itself up. Without understanding this, everything else is like putting a band aid on a shotgun wound.
