Excerpt:
It just wouldn’t be Halloween without pumpkins. Every year, billions of bright orange gourds are sold around the U.S., as children and adults alike mark the spooky holiday with some creative carving.
But there’s a sinister side to the fun.
After Halloween ends, people throw their pumpkins away, and they’re hauled off to landfills. Pumpkins in landfills rot — and when they do, those gourds expel gas.
When a pumpkin reaches a landfill, it decays under other waste as it’s left without oxygen, its orange flesh distorting and breaking down. The bacteria that decompose the pumpkins in this environment create the gas, a process known as biological methane production, which is only done by microorganisms.
The gas that is produced by landfills is about half methane and half carbon dioxide and water vapor, in addition to a small amount of other organic compounds.

New Study: Human Emissions ‘Irrelevant’ In Determining Changes In Atmospheric CO2 Since 1959
Climate science shock: Methane’s unexpected cooling impact unveiled
Demonized as contributing to climate change, cattle may actually decrease emissions, research shows
Galen Erickson, professor in the Department of Animal Science at the University of Nebraska-Lincoln, and Tala Awada, professor and associate dean in the Agricultural Research Division, said: “When optimized grazing is applied based on the climate and the region, there is more carbon sequestered than what cattle breathe out in CO2 and produce in methane,” Erickson said.
