When we look at the triggers of climate change, we see that methane gas emissions have an important place in this process. Although methane as a greenhouse gas is not present in the atmosphere in amounts as dense as carbon dioxide, the fact that the gas is much more effective than CO2 makes it very effective in this sense. The studies revealed, methane gas It traps 84 times more heat compared to CO2 over a 20-year period. is showing. Man-made animal husbandry is the main reason why methane is present in the atmosphere.

Due to the increasing consumption of animal food, animal farms opened in large areas and mostly with the destruction of green areas, according to some sources, the greenhouse gas emissions in the world. responsible for at least 15%. When agricultural activities are also involved, this ratio rises to 37%.

Methane emissions decreased in 2020
Well, in an environment where it is almost impossible to discourage people from eating meat, is there no way to lower these values? The answer to this question may be hidden in waterlogging. With the Australian Scientific and Industrial Research Council (CSIRO) and the University of California Davis The studies conducted by the researchers working for a while show that the additive of seaweed used in animal feed causes a serious reduction in greenhouse gas emissions.
Up to 82% reduction
The team’s recent research has been conducted over a period of two weeks to five months. During the said period, the researchers fed 21 cattle with food enriched with an additive made from seaweed grown in Australia. It has been observed that the seaweed species called Asparagopsis taxiformis breaks down enzymes that cause the formation of methane gas in the intestines of animals.
Average according to the results obtained by the research team measuring the methane gas emitted from the breath of animals with a special device four times a day. Control group consuming 80 grams of seaweedemitted up to 82% less methane than others. In the commercial part of the work, animals gain the same weight as others has been determined.
Another gratifying aspect of the work is that, according to the experiment, it was determined that the decrease in methane gas emissions was not limited to five months and the process was prolonged in a positive sense. The taste of meat consumed as a result of slaughter with the milk produced by cows has not changed, again, an important detail in commercial terms.
As with any research, the process is not without its difficulties. Considering animal farms on a global scale It is quite complicated to collect asparagopsis taxiformis in sufficient quantity and make it ready for use. a process. Similarly, how to give the additive in question to free-range animals is a separate mystery. Let’s see what kind of solution the researchers will come up with for the obstacles they are facing.
