The more apt question is not are there more hungry people in the world but is the ratio of fed people to starving people better today or yesterday?
Another question to ask is: If food production has dramatically increased, then why are there still hungry people? It's a rabbit hole. All we are accomplishing is increasing the real number of hungry people perhaps?
I think that you hit on the key problem that I have with the whole "Green" "AGW" mentality.
For sake of argument lets call it the "Green" movement. "Lets save the trees, ocean, air etc. Okay?
In their attempt to save these things they have invented a whole new category of a thing called `'stewardship" That we as a "community" have a "duty" to later generations "save the planet.
Agreed?
I think up to this point you will not find too many people in disagreement.
My question to you and other "Greens" would be, Do your stewardship rights take priority over my property rights?
Green movement? Sure. As long as people keep doing stupid things, the green movement will continue.
Case in point, the EPA is not currently prosecuting polluters who are dumping toxic waste into non-navigable waterways. This is since the Supremes ruled that the EPA has no jurisdiction over those waters as the law is written to cover 'navigable' waterways. I don't fault the Supremes for their ruling, they followed the letter of the law. They will only be 'activist' judges for more conservative causes
The waterways being polluted drain into watersheds used to supply drinking water, into fisheries, into navigable waterways, etc. in many cases. A 'green' person will never understand or accept those types of actions. Why should they? You expect them to give others carte blanche to poison the earth they live on?
What did the wingnuts do?, well they ran around the country telling farmers the EPA was going to regulate their rain puddles if given regulatory powers over all bodies of water. The farmers call their congressmen, the manufacturing trade lobbyists make visits and calls to craven politicians. So the end result is, stupid people are allowed to dump crap into the water.
That is insane by any standard. As long as that 'brown' mentality persists, there will be greenies around.
Extrapolate that to property rights. Do you really think a stream running through your property is yours to use as you wish? Just about anything a landowner does, the effects of which travel beyond their boundaries, should expect some resistance if those effects are injurious to others.
If you lived in a biosphere and dealt with
everything internally, that would be okay.

Don't expect the taxpayers to clean up another Super Fund Site after you are gone.
If I buy 20 acres in a rural/agricultural area - Should I be able build a stamping plant? Ka-chunka Ka-chunka 24/7? Open up a stone quarry? a little blasting and 50-100 trucks per day? Build a waste to elec. generator plant? How about a dirt bike race track? Races every Saturday night, track is open for practice Mon-Fri 8am-8pm? How about a mega-dairy farm which produces millions of gallons of waste which eventually enters the same aquifer my water well uses?
I could go on and on with enterprises that have a place, but most of us would not wish to have as neighbors. I think zoning is intended to address and adjudicate those issues. In every case, the owner of the 20 acres could complain that their property rights are being ignored. Isn't is simpler to create different zones for different uses? And even better, when purchasing a piece of property, align your intended uses with the current uses?
