Avoid non-biodegradables like chemicals and carbon products. I am from India and when I think why our ancestors were using and following non commercial goods and lifestyle. I get the answer today that they were future centric. How? if they have started using carbon products and chemicals like we do today to add little comfort to our lives and earn more and more money in our life and in a shortest possile span of time than probably we all people on earth must have been using some suite on our body to cover our whole body from the environment of Earth like austronaut do in there space walk. Just think for a moment for whom we are adding this big pile of money; for our future generations and what If they can’t get even some clean air to breath into and clean water to drink.
Lets see what our ancestors were doing. First of all they were using bio-digradable and natural products to run there daily life. Like they were using stones, mud, wood, metals(iron, copper etc.) to built there houses which do not harm the airable nature of Earth even after hundred of years. and what we do today is use sand, cement, plastics etc. to raise big houses and commercial establishments. And forget the land can be used in future to grow trees or crops etc. Coming to for earning there livelyhood what they were doing; buying and selling natural goods and by-products. How careful they were for there future generations, for us. Don’t think for moment that they were backwards and not knowledgeable guys. When they can predict what will happen in future and what will result in to what they could have possibly built big ships like we today have.
We are polluting our air like anything. Can’t we big technologist use some environment friendly techniques for our energy requirements. Answer is yes if our greeds resists us. The human beings who can reach Moon, Mars cannot be this incapable that they cannot use ocean energy or solar energy to develop some clean and safe energy to give our future generations some safe Earth to live in. We are running towards nuclear fuel instead of developing some clean and cheap energy resouce which any poor nation can afford to offer to its citizens.
Go green and save the future of your future generations. Otherwise they will only curse us for our greed and foolishness.
