Nope, this is completely wrong. People want to help but they have limited bandwidth. When you give them someway they can feel like they are helping without meaningfully doing anything, you’ve reduced their attention/effort that will go into real solutions.
Doing minuscule shit is absolutely harmful to the cause. This is one of those areas where a compromise is as bad as doing nothing with the additional downside of patting yourself on the back thinking you made progress.
Methane and Nitrous Oxide also play a massive role. We produce less of those mostly through gas leaks and shipping/diesel fuel but they are a lot worse than CO2 if we think of it in terms of per kilo impact.
It's a shame that a couple of generations have been led to believe that the only real environmental disaster is climate change. It's certainly a big and pressing one, but it's like we've all but forgotten the many other issues that our lifestyle of ready massive consumption has caused.
Some examples of other environmental impacts that 'reduce, reuse and recycle' helps with: the impact of mining and oilfield operations on the natural environment; heavy metals and other toxins in waterways from mining and badly managed landfills; microplastics in the ocean; acid rain from Nox/Sox emissions; many other forms of air pollution from the mining industry.
Just to name a few.
I am wholely in agreement with you but there are some pretty big percentage wise holes that we need to plug.
Namely:
1. Getting ride of coal and Natural Gas power generation (which means replacing with renewables +storage, or fission, none of which are easily deployable)
2. Stopping methane leaks in Oil&Gas pipelines and active/decomissioned wells.
And of course we shouldn't just ban or tax disposable vapers. But all disposable electronics.
Carnival Cruise's line of ships (which contain about 50 ships) contribute the same amount of emissions as all the cars in Europe. We could make the hard descision to regulate cruise ships away or maybe everyone in Europe could stop driving altogther
Yeah, Cruise ships are pretty nuts!
No. Stepping over dollars to pick up pennies is stupid.
These are the classical mistakes people make when optimizing software.
This way you end up spending a lot of effort to make your code 0.0012% faster.
I have no doubt this mistake will keep being made throughout all of human history.
