Whilst it's perfectly reasonable to claim "that human-caused climate change is happening" (
https://whatweknow.aaas.org/get-the-facts/), there aren't any practical solutions to the global scale problem - and you (the reader) really do need to think GLOBAL ! If you accept that, in its simplest form, climate change is driven by an increasing world population and rampant consumerism - then how are you going to solve that problem ? Humans have spent many centuries finely honing the 'materialistic' based society - the concept is embraced by most societies. You go to work to earn the money to buy the things to make you feel better and make your life easier. Bigger. Better. Faster. More. And so it goes.
By the end of today there'll be around 200,000 humans added to the world. So far this year we're looking at around 8,5000,000 additional people added to the world's population. Most of them will be driven by materialism in some shape or form. Think about what that means

Spend a minute watching the population counter spin ever upwards on this website
https://www.worldometers.info/world-population/ and think about the fact they'll all need to consume - some a paltry amount, some driven by greed, but they'll all consume. For every global benefit you score from your electric car, or triple insulated house, or working from home, or whatever - it'll be wiped out in a nano-second by the global increase in consumerism.
It's not practical to tell the world to 'Stop Buying Things' - partly because that's, ultimately, what drives people to get up in the morning, and partly because that's what drives the global economy and keeps people in business and taxes coming in to governments. It's also fairly impractical to try and control the global population increase - only wars and pandemics are good at that sort of thing.... and I can't see that happening any time soon
Whilst I really do admire Greta Thunberg for standing up and getting the headlines (and I really do like her for peeing off Trump

), there aren't any practical solutions to the global problem. Sure - you can make the Earth habitable for a little longer if we all strive to be 'green', but unless you knock 'consumerism' on the head or send the world population into gentle decline, mankind is still going to be stuffed in one way, shape or form
In its simplest form - will mankind stand a better chance of long term survival with more people on the planet, or fewer ?
