imho the easiest way would be to start buying local food instead of importing the worse kind of budget #@&"(.. you know - doing market or buy cheese at farm directly. 2nd way could be to stop factory's medicine and find some nice herbal products to cure some ill. Also if you are in peace with your neighbors and get some bread for them when you are going to baker - and improve some relationship that way - that would be a good exemple for children and peace around...

People don't need too much to find some happiness - when it could be a glass of wine with friend. Humans are probably the biggest threat for themselves - so if they decide to consume only basic needs - having more game and fun with their entourage - they will probably keep a nice weather for next generations. Otherwise they can try to mine and trade more and more to get more money that they can spend - to finally return in dust and oblivion like the failure they look in the mirror... well that is sad - we are all different - but we should probably do what we thought right for children. And that will probably be the hard way  - but even better it will be - like satisfaction in accomplishment.

cheers
