Melestarikan Sumber Daya Dunia - Bagian ke-1 dari 3 seri

Whatever you use, consider the world’s resources, not your money. Everything we are using, belongs to the whole world, even if you pay for it. It’s not that I’m telling you to be ascetic or anything, but you should consider always all the efforts that has been put into whatever we use, and all the resources that must be utilized in order to give us a comfortable life. So the less we spend the world’s resources, the better, no matter how much money you have.
