Ann: Tin Drilling intersects second Skarn at Mt Lindsay Project, page-94

I always wondered how they determine the carbon absorption of forests, I guess the growth of biomass as a percentage is the best they can do. If a forest has zero biomass growth then we can assume minimal absorption. Wonder if algae farms would make ideal carbon sinks, as they seem to grow fast, eh! I guess its more academic. Well hopefully some of the greenies work out that Tin is required to reduce carbon emissions, no tin no solar panels, No solar panels are its time to use coal to get power required for society to function.
