See, this is the problem with you Yes/No people.
Look, it's fairly easy to cut your carbon emissions in half, without radical change. You're just to lazy to accept change.
For example, the future is presented as: We Must All Ride Bikes.
But, to cut carbon emissions from cars in half, it's fairly easy. In a typical family, have one plug-in electric car, charged from green solar/wind/hydro, used for commuting. And have a combo of bike plus transit for the kids. This way, fewer fat kids, you save tons of money, and it's the way we used to live just a few decades ago.
Easy peasy. You can replace inefficient applicances with efficient ones, LEDs are now 94 percent cheaper than they were in 2010 and way brighter than old incandescents. You CUT YOUR ELECTRIC BILL.
Stop whining, grandpa. Adapt. The world doesn't care what your excuses are.
