I think you're genuinely thinking about solutions, but, your knowledge base needs working on.
"fertilizer and pesticides, which honestly don’t matter climate wise"
They honestly do matter very much!
The "climate" isn't some abstract phenomenon that exists outside of the planet's ecosystems. Insects are fundamental components of an ecosystem. Insecticides kill insects!
Overuse of fertilizer, both organic and synthetic, runs of the land into rivers and oceans (i.e., more pollution)
"If we are to replace fossil fuel in heating"
You make it sound like a choice.
I don't know where you live, however, in the UK we've had decades of government incompetence; because they're "buddies" with the fossil fuel industries.
So, if they hadn't been so crap, we could have had well-insulated buildings that were heated using heat pumps.
The obvious point is, ALL sectors of what's called an economy need to either be more efficient or go out of business.
Do you mean that the technology does exist, but, for example, the fossil fuel industries want us to use the technologies that keep them in business?
I've also heard that the owners of shops want to sell their products (it's not speculation)
And then there is your average consumer, or at least where l live, who is either not thinking that much about pumping fuel into their 'beloved' CEV or is concerned, but, for example, it's not as if governments & industries are helping
@riodoro1 @blanketswithsmallpox @climate
They do fabricate a lot of BS to deflect the attention away from the problem. Burning fuel!
Reduction via energy efficiency & switching over to electricity, via wind, solar, water (wave, tidal, hydro) & thermal is right direction of travel. So yea, electric public transport, instead of private cars, generally does the same task, with far less resources (inc. power demands)
