The two main human activities that affect the carbon-oxygen cycle arethe burning of fossil fuels and the use and change of land. ... While crops may produce oxygen and take in and use carbon dioxide, livestock produce a much larger amount of methane (CH4). Is carbon a cycle? The carbon...
" Well, they might not be entirely wrong to say that. Two out of three humans regularly produce toots without any methane in them, while one out of three always produce methane. Scientists are not fully sure why this is, but some of them suspect that there's a genetic aspect to it, ...

Eötvös Loránd University, Budapest (ELTE) compared human-oriented communicative behaviors of young miniature pigs and dogs kept as companion animals. They found that in a neutral situation pigs turn to humans, initiating interactions as much...
Globally, trash released nearly 800 million metric tons (882 million tons) of CO2 equivalent in 2010 — about 11 percent of all methane generated by humans. The United States had the highest total quantity of methane emissions from landfills in 2010: almost 130 million metric tons (143 million...
Scientists at NASA are particularly interested in the lake because its distinct environment — lots of methane and low temperatures — may be similar to those of other planetary bodies, such as Jupiter's moon Europa [source: NASA]. Acidic Environments As we've mentioned, some of these ...
Here’s where we get into specifically why SpaceX sees Methane as an important, or even a necessary part of their companies future. SpaceX’s ultimate goals are to develop a system capable of taking humans out to Mars and back over and over. The Mars atmosphere is CO2 rich, combine that...
Humans don’t play by the same rules that nature does. When we extract, refine, transport, and burn fossil fuels like coal, natural gas, and oil, we release extra carbon and other greenhouse gasses into the atmosphere. We also cut down large expanses of CO2-absorbing trees to make way ...
Methane is an even greater threat to Global Warming because it traps and holds heat 21 times as much as carbon dioxide. Methane (natural gas) is a byproduct of oil drilling and production, organic material breaking down in landfills, and natural gas emissions from rice paddies, animal manure...
"The United Nations Food and Agriculture Organisation estimated that industrialised countries generate approximately 95 to 115 kgs [209-254 lbs] of consumer food waste per capita," de Groot told Mashable. "This contributes to climate change in the form of methane emissions emanating from landfills ...
