According to Science daily, Prof. Dan Yakir of the Environmental Sciences and Energy Research Department in the Faculty of Chemistry has discovered a way to trace pollution back in time by analyzing the carbon isotopes found in newspapers and magazines. Using this method, scientists can track the amount of pollution due to the combustion of fossil fuels. This method has been in development for fourteen years. This discovery can allow scientists to track pollution as far back in time as they can find paper. The analysis is based on the amount of Carbon 13 molecules in comparison to Carbon 12 molecules, and works similarly to Carbon 14 dating.
Wow! I think this such an interesting article! That we can trace pollution back to different centuries, and we can do it all through paper! All we need is a little paper, and a scientist, and we can check on how pollution has progressed throughout the years. We will deffinitely see that pollution has increased, and we can hopefully take some different precautions and steps to try and cut back on our pollution.
ReplyDeleteHere is something to look at people are blaming all of the pollution on what people are doing today but what they do not think about is what happened to our environment years and years ago. There is really no way to know the life that was really lived hundreds of years ago because we were not there but this is a little stronger because it is proven scientifically.
