This Australian farmer, about 20 yrs ago, decided to environmentalise his farm.
He planted trees, sheep rested under the trees, their wool grew better and therefore more valuable.
He planted local plants, water was reclaimed in the roots of the plants and when other farmers had to buy water he did not.
He stopped caged hens and now sells his barn laid eggs for much more.
A hybrid car will with care need a VERY small amount of petrol and therfore eventually save YOU money.
Humans have only used oil for 150 yrs and we have used up over half of it. It will run out.
We've grown wheat and other things for 1,000s of years and such things can be made into fuels.Have you ever seen sun-flowers grow, they nee NO ATTENTION and can be made into sun-flower oil to run vehicles
Humans managed quite well, rich and poor, happy and sad with-out modern stuff. YOU can actually make money and happiness out of helping environment.
