With Chickens and how Cows are treated is a moral issue and not an efficiency one. Efficiency is what made the horrible conditions those animals are living in, its cheaper and uses less space to cram a bunch of chickens in small cages and faster to have machines rip them apart. You can make a complaint and have more sane treatment of animals but less efficient way of killing them. The people have a choice in this and can support or not support these practices with their money. People continue to support companies that do this so its why they keep doing it and seems like most don't care, they just want food on their table. But it is still a moral Peta animal treatment issue and not efficiency one.
Food Production and Fossil fuels would be 2 separate topics. It isn't the fault of the farmer that he is stuck with fossil fuels because of the corrupt fossil fuel industry. Fossil Fuels is all he has to produce his crops so that's what he uses. Just like how you driving a fossil fuel car not being your fault. But it's the best you have right now so you use it.
Food is cheap because competition from the market made it cheap. It gave the limited crops to people that can produce it at a cheaper price, compare food prices now and 100 years ago and you'll see how much cheaper and convenient its become, and the people that weren't able to keep up with cheaper prices went out of business. So food, an finite resource, was transferred to more efficient hands, and eliminating inefficient people. Which is the opposite of the fossil fuel industry, they kill competition, they kill alternative energy resources. Which means there is no competition in the market to threaten fossil fuels, which allows them to not improve to produce the most efficient green way possible since they have no pressure from competition to improve. So there is no market competition to put those finite resources in efficient hands. But when there is competition like in the TV industry then you get efficiency, you get prices that come down and you get a better product.
So how would you solve this issue to allow competition to happen, so that they have motivation to out do their opponents which means better stuff for us. To stop them from stiffing competition and keep money out of politics? Capitalism is not the issue but Crony capitalism is. People making too much money in this economy and using that money to buy politicians in their favor. Should we put a cap on how much money people are able to make so that they wont have excess money to buy politicians? Knives are not the issue but how people use those knives are. Guns are not the issue but people that kill are. People suggest that banning guns will solve gun violence so will the same apply to money? Ban money? What would you suggest to solve this issue and get people to stop buying politicians. Tell them not to? Pass laws and hope they will be a good little boy and follow rules? How many people actually follow rules? How would you stop them from making underground off the table illegal deals?
