Pondering Planet Payback: Elements

1. If the plants complete the various cycles (such as carbon cycle, nitrogen cycle, etc) by returning what they have taken from earth, we humans can also do the same, especially with our great knowledge, sixth sense and technological advancements that we feel proud of.
2. Since is would not be able to return the ores back as they came, the usage can be reduced. More of recycling of already used materials is the best option possible.
3. Whenever something is thrown away as trash, minerals available in these thrown away components can be removed.
4. It is easy to remove metals and non-metals by many chemical processes and bring them back to their pure state.
5. This is economical as there is no or low costs involved in procuring the raw materials. Trash comes for free and only costs are transportation costs and extraction costs. However, these would be cheaper than the ore-extraction and purification costs.
6. When gold and silver are recycled to eternity other metals should also be treated as precious and can be recycled and reused many times.
7. Recycling would offer new job and business opportunities. More skilled labor force will become employed as there would be more industries offering trash-to-cash opportunities.
8. The consumers would pay lesser costs, as the costs of production will be reduced. So, the market will be higher for such recycled materials.
9. In case or ore extraction, the unwanted materials should be sent back to earth, just like the unwanted fish is thrown back from the trawlers (though most of them die before hitting back the oxygenated waters!) This would ensure that the minerals are not depleted completely.
10. Prevention of corrosion is one of the key factors in paying back to earth. Only if something is corroded, there would be demand for a new component. Therefore, prevent corrosion and do cost-cutting for procuring new materials, in an eco-friendly way.

Being friendly to earth is the only best possible economic way to ensure survival of mankind. There are no other cheap alternatives.
