Often the obvious solution to problems can't be seen because money gets in the way. Without money, difficult even moral problems become easy. Without money complicating everything there'll be no motivation to make things that are unhealthy for society. We can then have a needs based economy that's able to achieve what we need that currently can't be because it doesn't make money.
There'll be no motivation to make food unhealthy and without the stress of not having enough money or having too much money there’ll be much less reasons to eat unhealthily. The motivation for growing food will go from making money to providing good nutrition.
There'll be no need for pesticides and herbicides and genetic modification. There'll be no need for mono-crops that cause desertification and flavour enhancers and artificial colourings because there'll be no competition between multinational food conglomerates. There'll be no need for artificial preservatives or picking unripe fruit that's acidic because food won't need to sit on a shelf in a supermarket. Without money people will grow food near to where they live ending the need for fossil fuels.
The end of money will kill the motivation to kill adult orangutans to make it easy to take their babies for the entertainment industry. The puppy mills and industrial factory farming will go out of business and scientists won't be able to get people to hunt down monkeys to experiment on. With money taken out of the equation, effort will go into creating medicines that will do the most good not make the most money.
The wealthy won't be able to get people to kill elephants for ivory or kill rhino for make believe medicinal medicines or kill whales and dolphins for 'cultural reasons' or get people to make their bed and cook their food and wait on them hand and foot. The service industry will die a welcome death. Everyone will clean their own toilet and have the satisfaction that comes from cleaning up one's own mess.
There'll be no way to enslave people in debt or get people to work in slave-like conditions. There'll be no reason to get children to work in prostitution, there'll be no excuse for prostitution at all. Without money in the equation people will no longer be able to trade money for sex. There'll be no motivation for pornography, drug dealing, stealing, and the arms industry.
There'll be no insurers, no bankers, no accountants, no lawyers, no judges, no politicians, no police, no corporate executives. There’ll be no copyrights or patents, no secret technologies. Everyone will become makers and sharers, working together not against each other. There'll be no need for paper shufflers.
Everything becomes easy without money. Even tricky questions like euthanasia. No longer will there be any concern about the cost of caring or if there’s an inheritance.
Just like that, getting rid of money solves almost everything including taking away the motivation for deforestation, stripping the oceans, polluting and mining. It's amazing how simple making decisions can be without money complicating everything.
