The growing popularity of unpasteurized milk in the United States raises public health concerns. We estimated outbreak-related illnesses and hospitalizations caused by the consumption of cow’s milk and cheese contaminated with Shiga toxin–producing Escherichia coli, Salmonella spp., Listeria monocytogenes, and Campylobacter spp. using a model relying on publicly available outbreak data. In the United States, outbreaks associated with dairy consumption cause, on average, 760 illnesses/year and 22 hospitalizations/year, mostly from Salmonella spp. and Campylobacter spp. Unpasteurized milk, consumed by only 3.2% of the population, and cheese, consumed by only 1.6% of the population, caused 96% of illnesses caused by contaminated dairy products. Unpasteurized dairy products thus cause 840 (95% CrI 611–1,158) times more illnesses and 45 (95% CrI 34–59) times more hospitalizations than pasteurized products. As consumption of unpasteurized dairy products grows, illnesses will increase steadily; a doubling in the consumption of unpasteurized milk or cheese could increase outbreak-related illnesses by 96%.

Found a good patch. Will be inaccessible if it rains again though.

Not a student currently, but I'd guess CH4 + O2 = H2O + CO2, which is methane combustion. Let's see, to balance, well, we've got three oxygen on the right side, two on the left, so at a minimum we need to increase to 2O2... So where did that leave it? 4 hydrogen versus two, so 2H2O... Now that is four oxygen on the left, four on the right, yep all equal.

So, CH4 + 2O2 = 2H2O + CO2 is the balance. And I'd guess the climate relevance would be something to do with the use of natural gas for heating or energy production.

Sharing instead of commenting because while it was mildly interesting to exercise long disused skills, commenting would put the answer right below the question and short circuit actual students from trying it.
OK science students, which molecules are represented here, what is the importance of this chemical reaction to earth science, and how should it be balanced?
