Wow.. this is tragic! I feel like I don't know what's going on on our planet. It's terrible if you think about it, you don't know anything, nothing is different than on any other day, it smells the same, looks the same and still everyone collapses and suffocates.. that's terrible! I hope that the degassing is taking place everywhere where this could happen on earth to prevent another tragedy, like the one in 1986, from happening!
