Besides fuel, some kinds of seaweed have another excellent effect: when fed to cows and other ruminant animals they prevent the formation of methane. Cows’ burps and farts account for a major portion of the increasing levels methane resulting from human activities.((“Methane emissions from cattle are 11% higher than estimated,” //The Guardian//, Sept. 29, 2017. https://www.theguardian.com/environment/2017/sep/29/methane-emissions-cattle-11-percent-higher-than-estimated)) | Besides fuel, some kinds of seaweed have another excellent effect: when fed to cows and other ruminant animals they prevent the formation of methane.

- | Oysters also absorb carbon but they truly excel at filtering nitrogen out of the water. Nitrogen is a greenhouse gas nearly three times as potent as carbon dioxide. As the main component of agricultural fertilizer, it is a huge pollutant, emitting greenhouse gas to the atmosphere and then floating downstream to lakes and oceans, where it depletes the oxygen. But every oyster can filter thirty to fifty gallons of water a day.((Hawken, op cit. p. 204.)) | + | Oysters also absorb carbon but they truly excel at filtering nitrogen out of the water. Nitrous oxide (N<sub>2</sub>O) is a greenhouse gas with 300 times the greenhouse gas action of CO<sub>2</sub> in its first 100 years in the atmosphere. |
