Yes, increased intake of Mexican-style food (particularly "refried beans" which are a staple of a large number of Taco Bell's offerings) is causing the earth's temperature to rise. Everyone knows that Methane, CH4, is one of the greenhouse gases that is causing the recent surge in the earth's temperature (which obviously is human-induced, not at all related to the earth's cycle of coming out of an ice age). When you eat food like beans, you get gas, and you fart. And farts contain methane. Increased farting leads to increased levels of methane in the atmosphere, which leads to the earth's temperature increasing, of course (the earth, having been around for however long it's been here, couldn't possibly regulate itself in these amounts of greenhouse gases). In addition to beans, it is surmised that fried foods and onions also lead to flatulence; for some suggestions on eating habits that would help curb flatulence, see the wikiPedia article here.
Another leading contributor that has heretofore gone unnoticed is the invention of the soda. Sodas make use of carbonated water, which is water into which carbon dioxide (CO2) has been added (by dissolving under pressure or other means). Carbon dioxide is another greenhouse gas. The increasing consumption of carbonated beverages (in the US and in the world in general) lead to increased amounts of CO2 in the atmosphere (both from carbonated water "losing" its fizz to the atmosphere and through ingestion in humans, where it can cause carbon dioxide related flatulence), which in turn leads to increased global warming.
Since humans breath in oxygen (O2) and breath out carbon dioxide (CO2), the increasing population of the world must have some effect on the amount of carbon dioxide in the atmosphere, too.
Thus, there are three things that we can all do to help mitigate our impact on our giant earth and its atmosphere (all 5.1361×10
- eat less Mexican-style food
- drink less carbonated beverages
- die (of course, this also would entail decomposition after death, which would produce gases, including methane and carbon dioxide; further study is needed to ascertain whether the decomposition process would be more or less destructive to the environment, but of course since everything's going to eventually decompose anyway, not-dying may just be a stalling course of action, and the alive-breathing contribution to the greenhouse gas carbon dioxide will be allowed to continue for a longer period of time)
*Note: no actual studies were conducted; instead, this is a summarization of the author's thoughts and research based on readily available resources, and it sounds better to say "recent studies show." The reader is suggested to conduct his own research into the publicized topic of "human-induced global warming" - for example, consider this article, these news stories, and this site's information.
