Found a way to reduce methane production from animals on farms

The climatic changes that are happening now on the planet to a large extent are controlled not only by industrial sources of pollution, but also by livestock and animals – according to statistics, in America alone, up to 10% of substances that negatively affect the climate in the face of methane are reproduced precisely from for the livelihoods of farmed cattle. So a team of specialists from several world universities decided to correct this misunderstanding by proposing a new way to significantly reduce the emission of methane as a by-product of their vital activity – by changing the intestinal bacterial biome itself.
Scientists undertook a careful study of several groups of animals and found that the most risky group are sheep – they are the record holders in the reproduction of the greatest amount of methane into the atmosphere. Despite the fact that methane is not so voluminous in comparison with carbon dioxide, it is still more dangerous because of its ability to accumulate a lot of heat. In order to minimize this feature, the team of scientists decided to experiment with a change in the intestinal biome in such a way as to reduce the production of methane. After lengthy research sessions, they found that they should target precisely bacteria called methanogens – they are responsible for the production of methane.
By changing the diet of livestock in some way, they managed to not only reduce the level of methane reproduction, but also generally improve the work of bacteria such as ruminococci and clostridia.
This means that animals can now boast a generally stronger and better immune system and more reliable cell division – due to the fact that their main intestinal biome has been changed to one that does not involve the release of a large amount of methane. However, experts still have some doubts about the correct selection of experiments, and therefore they are interested in additional sessions.
