What I heard (read) is tha beside swamps, the main source of natural methane is cow (and other ruminant animals') fart. That still may (or may not) be odourless, @PaulPavlinovich 😄

@ErmesT I was going to PM you but I don't see a way to PM you. I would like to participate with Environment & pollution on maps! It would very good project to participate in because it affects all of us world wide. I have been documenting things on my own for several years now. People are just dumping all over! My documentation is scattered all over but I sure can search it to find older post to share with environment & pollution. I live in the Walthour swamp Savannah Georgia, where they are using landfill from a borrow pit, to fill in the swamp, raise land to build brand new houses. They are blocking St Augustine Creek to drain in to lagoons, which is just water retention of the tidal basin. The Borrow Pit has been cited with environmental pollution. We have a county abutting right next to us, that used coal ash in roads 20 years ago, that have fallen apart. Now the coal ash is loose & is polluting the swamp. Georgia is treating the environment really poorly. The images from the past have shown that the city of Savannah encourage residents to dump trash in the swamp land. The problem with this is we live on the water table, on land that was previously reclaimed by the water. They just dig a few canals & lagoons & levees, then think that is enough to prevent problems with the area. However they are making it worse as they cut down all the trees. Savannah Georgia is a literal example of draining the swamp! We have a mix of garbage pollution methane & swamp gas methane release. I've lived here 12 years and it has gotten really hot & muggy since they removed all the trees. When it gets hot & we have a drought, the ground contracts & shrinks. When its rainy, the ground gets really mushy. Our driveways are cracking really bad since we've had more moisture & water pushing up from below. I'm in a new housing development & the roads are already flooding. Building houses here is not a long term investment for homeowners, where the locals are hiding the history of the land. They have told me we should have done our due diligence before moving here. Since the locals hide, make it harder to find & change the history of the land, there is no history of the previous owner, or if the land is part of the Savannah Wildlife Refuge. I know Chatham County has an ordinance where they are supposed to leave trees because trees help prevent coastal flooding. Where I live, they build hundreds of houses in an AE flood zone, which is a high risk. Someone told me where we live used to be a lake, completely under water. From the air, it would be impossible to see, because trees were here. The real estate agent told me this used to be a tree farm, so I had no reason to not believe him. We thought we were moving on real land. How is living in a former lake, in swamp land safe for residents? With the marketing they are doing, most people who move here have no idea this is real swamp land.
