An empathetic person is someone who can share another person's feelings. If you tell an empathetic person that your heart is broken, she might touch her own heart and gaze at you sadly through moist eyes. Empathetic is a recent term; it comes from empathy, which was coined by the German philosopher Rudolf Lotze in 1858. Lotze believed that when you look at a work of art, you project your own sensibilities onto it.
Landfills are the single largest human source of methane emissions in the world. Even with the best technology, most of the methane from landfills is released into the atmosphere. By composting, the generation of greenhouse gases, particularly methane, is avoided.
Methane can be produced by hydrogenating carbon dioxide through the Sabatier process. Methane is also a side product of the hydrogenation of carbon monoxide in the Fischer-Tropsch process.This technology is practiced on a large scale to produce longer chain molecules than methane.ethane has a large effect for a brief period (a net lifetime of 8.4 years in the atmosphere), whereas carbon dioxide has a small effect for a long period (over 100 years). Because of this difference in effect and time period, the global warming potential of methane over a 20-year time period is 72.
