Can the Left be saved?
I think the question is more accurately "Can the Right Be Saved". It is pretty obvious that the Left is proposing advancements in human development and safety. There has to be better health care systems, attack gun controls, international trade, and climate improvement.
The Left is proposing those. The Conservatives are demanding that we maintain our failing health care systems, allowing angry people to have military weapons, destroying long-standing international trade agreements that have been to our benefit, and takibng financial benefits at the cost to our children for short-term benefit.
This kind of "me now" attitude simply cannot be allowed to continue. It must end.
We have evolved from small individual groups to camps to villages to towns and cities that succussfully used all available recurces without much penalty. That time has ended.
Collectively, we are now as a species threatening our very existence. At some point, there may simply not be enough enough oxygen in the air to support our rather impressive brains. It has been higher and lower.
We are on the verge of making it lower again. As we deforest the planet, we are reducing the amount of oxygen in the air. It is little difference toady, but it will increase as we burn the Amazon forests and turn more land to crop production.
A field of crops do not provide the same amount amount of oxygen as an equal area of jungle.
Won't it be ironic if we simply due from lack of oxygen that rather fall to some aliens, LOL? You think that can't happen? Ask those 4' wingspan dragonflies that used to exist when the oxygen level was 30% instead of 20% today.
