Electronic products and accessories always generate carbons filled around the environment. Carbon is the main embalmer of pollution, a surfeit of carbons will cause a critical destruction of our nature, when we should keep those electronic products in off-mode power when they're not in use. They should've been thoroughly stopped running in order to saving energy.

On the basis of 414 soil profiles from 14 provinces, it was found that soil organic carbon, differing from soil inorganic carbon and other elements, has a trend of exponentially decreasing with depth. Integral analysis of exponential curve contrasting with the linear model affords the uncertainties of linear model and exponential model for carbon storage calculation. It was found that the integration of TOC with the linear model has errors between +20% to +100%, much higher than that of the exponential model (-10% to +20%).
