You're expecting things to get very bad very soon? Global climate change is going to reduce the land available for people to live on, and also crops.

Jesus will remove His beloved before martial law. The US gov't. will only impose martial law as a last resort. They don't want us locked up in camps because they want us to go to work every day so we can buy their oil.
