Notanan as I understand it you would like to return to the Stone Age when we all lived in caves with one small fire per cave per tribe and otherwise using no energy.
I assume you now live in an unheated house and never travel on any kind of transport that uses fuel or buy any goods, including food, that consumed any fuel in production or transport.
The answer to both queries, is of course you don't. We are where we are and we know we now need to reduce green house emissions. There are many ways of doing this. The UK has reduced its emissions by 40% since 1990, mainly by closing coal fired power stations. World air travel only produces 2% of total world green house gas emissions.
What we must do is gradually make changes to move to a net zero economy. There is no reason why people should not continue flying, but simply take fewer flights or move some journeys to rail if that is possible, and it often is. Even before recent announcements about the phasing out of the manufacturing of hydrocarbon fuelled cars, cars had become much, much more efficient and were producing much less carbon dioxide than they did 10 or 20 years ago. CH boilers are much more efficient, houses better insulated.
These changes to electric cars are only possible because of the growing amounts of money being poured into research into better battery technology. Lorries will possibly move to hydrogen power, there isn't a hydrogen lorry engine yet, but there will be soon. Planes may be able to do the same. Bit by bit, at an accelerating rate we are cutting emissions.
As I said, if you want to turn the page back to the 17th century or earlier, for yourself, please do so, but I cannot see the point when just some modifications in our behaviour, some thought about how we behave means we can do the job just as well in comfort.
