Make sure to include the time and inputs to make the grass, and especially trees; those don't just appear out of nothing. And we already know how it works, it's called logging.

None of the inputs required for plants to grow require toxic pollution or destructive extraction. Of course humans can bring in toxic or destructive inputs to try to favor certain plants over others, or humans can do other non destructive things to favor certain plants over others. Or humans can step aside and let the plants do their thing which will create abundance too. (I like the middle of these three.) Also, trees provide far more value than timber alone.

  Would you give up fertilizer and pest control and stop feeding the 8 billion ? Please dont be a holdomorehippy.. Those back-to-nature loving massmurderers without a cause creep me out beyond repair.. those that openly hate some humans at least give the monstrous game away.

    Eventually, you won't have a choice when fertiliser produced from oil runs out, becomes cost prohibitive, or is made illegal due to greenhouse gas problems; likewise, "pest control" has already resulted in a 40% decline in insect populations; it won't be good if it gets to 100%. It would be best to find sustainable ways to grow food now, instead of continuing unsustainable ways (including supplying massive food aid to unsustainable populations so they can keep growing) until there is a precipitous crash. The idea that only industrial scale farming can feed the planet is mostly a myth promoted by producers of industrial scale inputs and the oil/gas industry, by the way.

      > Eventually, you won't have a choice when fertiliser produced from oil runs out, becomes cost prohibitive, or is made illegal due to greenhouse gas problems You mean, aside from the process of making ammonia using green hydrogen that doesn't use fossil fuel at all? A process that can be sustained indefinitely, using renewable energy? The single big concern is nitrous oxide emission from bacteria in the soil, but that can be reduced by nitrification inhibitors, some of which can be produced naturally by plant roots (and likely engineered into crop plants.)

        Promises of “green hydrogen” and fertiliser made sustainably haven’t panned out. I’ll believe them when I see it, but I’m not a believer in industrial farming, which is more akin to mining.

        Green hydrogen can't compete when natural gas-derived hydrogen is allowed to dump its waste CO2 into the atmosphere. That doesn't mean it can't or won't work when natural gas is outlawed. Your evidence shows nothing except that CO2 isn't being controlled.

      Fertilizer is mainly made from natural gas, not oil. Accordingly it should last much longer. Worse case scenario when we run out is we switch to less efficient production, for instance splitting water using nuclear power. Any plan that relies on depopulation isn't going to work and any attempt to force it to work would require crimes against humanity.

      The production of concentrated nitrogen compounds from thin air is useful enough that we'll almost certainly keep doing it en masse in an electric-only future. Mining for phosphorous and potassium fertilizers, likewise, but situationally a little different because these aren't very mobile in the groundwater column like nitrogen is, and they don't offgas back into the air like nitrogen compounds do. Quite possibly we'll be mining manure lagoons more, for CH4 and for closing the loop better on P and K. Ag will continue at industrial scale for cereal grains, because half the population is not going back to the fields. Within that framework, there's a lot of difference between outcomes in terms of how green we make our farms, what we grow, how we grow it. Herbicide and insecticide practices do not have to be what they are, as we witness massive overuse of things like neonics, glyphosate, and aminopyralid mostly because there's little financial reason to constrain use. We could stand to dramatically reduce the amount of cereal grain we consume, from a diet perspective, but the logistical difficulties of alternatives like more fresh fruits & vegetables will tend to increase carbon emissions. Eating less grain-fed meat and more high-protein legumes is basically a win-win from diet and climate perspectives. Returning to a less industrialized industry where livestock are raised on farms instead of on "feeding operations" seems like a fair tradeoff against something like subsidized corn-ethanol production. Attempting to encourage long-term soil stability with reduced tillage and is another goal that we might tangle with that would reduce yields; We have plenty of yield to spare in the US, so this is an option.

  To be a pedant, the inputs for photosynthesis are pretty toxic to humans. Sunlight burns and causes skin cancer. CO2 also kills people each winter when space heaters aren't properly vented.

Whose time and what inputs are required to make grass and trees? If you simply leave a place alone, it will turn into either a forest, a grassland, or desert (the latter when human activity has thoroughly destroyed it).
