Globally Cows produce 150 billion gallons of methane per day. Methane is a greenhouse gas and has a global warming potential 86 times that of carbon dioxide on a 20 year time frame.
The effect major effect that cows have on the greenhouse effect can actually be reduced and the secret lies in seeweed.
Reasearch has shown that when cows eat a specific type of pink seaweed called Asparagopsis, the gas release of the cows decreases by a incredible 99%.
The seaweed interacts with the microbes in the cows and completely neutralizes methane which leads to less gasses release for the cow.
Australian reasearchers have shown that this is the one type of seaweed that is creating this effect and they are in full work mode to develop mass production in Australia of this type of seaweed. The idea is not to stop with Australia but to mass produce it for global use.
The biggest hurdle is the consistent production of the seaweed, as the remaining issues such as quality of milk and health of the cow are cleared.
The cows are eating seaweed as part of their diet, therefore it is not something new that is introduced to them.
If Australia can feed its cow population with the pink seaweed, it can successfully cut the gas emission by 10% as a country.
If this project is successful then the environmental consequences are huge. This could help countries that want to be carbon neutral to reach their goals faster and save billions of dollars as they do it.
