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 form an EXPLOSIVE mixture in air at levels as low as 5 percent. You can smell leaking methane only when commercial gas utility companies add a chemical smell to it or when it mixes naturally with hydrogen sulfide, causing a rotten egg smell. If you can smell it, the level may be too high to be safe.ethane can also be found in coal gas. Pockets of methane exist naturally underground. In homes, methane may be used to fuel a water heater, stove and clothes dryer. Methane evaporates quickly.
