The article reports on botanical research conducted by Zhi-Ping Wang and colleagues of the Chinese Academy of Sciences in Beijing, China who took samples of 44 plants to test for the release of methane. A woody shrub, Achillea frigida, released small amounts of methane, but Wang feels the ...
Here’s where it gets tricky. 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 C...
In actuality it’s not as much the farting that’s the problem, cows’ burping and manure contribute more methane gas than flatulence. According to researchers at New Zealand’s largest Crown Research Institute, AGResearch, up to 95 percent of the emissions comes from the cow’s mouth ra...
Elephants produce a lot of methane gas as a by-product of digestion. Scientists estimate that the amount of methane they emit in one day would be enough to power a car for 32km. Wild Asian elephant in Sri Lanka. © Tony C French/Getty ...
How can humans reduce CO2 emissions? How does the climate system connect with carbon dioxide? How does carbon dioxide affect biodiversity? How do non-green plants carry out photosynthesis? How potent is methane as a greenhouse gas? Why do larger plants transpire more than smaller plants? Explain...
Describe how methane gas can be generated, and explain why it is considered to be a greenhouse gas. Completely explain the greenhouse effect. Which gases are responsible for the greenhouse effect? What agricultural activities contribute to a global increase of greenhouse gases in the atmospher...
Ruminants’ higher LCA EIs are due mainly to the methane that they emit during rumination, which contributes greatly to GHG emissions (de Vries and de Boer, 2010), and to their lower feed-use efficiency and fecundity, which means that they require more resources over their lifetimes and ...
LCAs havefoundthat electric cars emit less carbon dioxide (CO2) than standard cars, butcarbon dioxideis an organic, colorless, non-carcinogenic gas that has no toxic effects on humans until concentrations exceed at least 6 times the level in Earth’s atmosphere. Thus, CO2 has no bearing ...
Methane in the atmosphere is a real powerful greenhouse gas, therefore it is actually better when it is burned and split into CO2and H20, as far as greenhouse gases go. HOW MUCH DO DIFFERENT ROCKETS EMIT? So let’s see some real data on some real-world rockets. For this let’s look ...
d said that the newer more efficient engines produced “more water”, and while it’s true that the cleaner the combustion the more water is produced, the difference is negligible for the two engine types discussed. The key difference is the exhaust gas temperature, as explained in the more...
