<unk>  (also called belching and eructation) is the release of gas from the upper digestive tract (esophagus and stomach) of animals through the mouth. It is usually audible. In humans,<unk>  can be caused by normal eating processes, or as a side effect of other medical conditions. In human cultures, there is a range of levels of social acceptance for<unk> . In some contexts and cultures,<unk>  is acceptable, while in others it is offensive or unacceptable. Failure to burp can cause pain or other negative effects. Humans are not the only animals that burp: it is very common among other mammals. In particular,<unk>  by domesticated ruminants, such as cows or sheep, is a major contributor of methane emissions which cause climate change. These burps are one of the main negative impacts of animal agriculture on the environment. Significant research is being done to find mitigation strategies for these burps, for example by modifying animals' diets with Asparagopsis taxiformis (red seaweed).
