First let me say I am not into doom and gloom as a way of life.
But if you are really concerned I suggest the following:
Stand in your front yard and look around, do you see grass (lawn)? In some areas you have a required lawn, but if you don't, dig it out and replace food bearing plants that grows well in your area. Look at your trees? If they are not fruit or nut trees.....time to replace.
Next look at your back yard....

Realize what you need vs what you want and start saving money spent on wants by skipping them, you can save a lot by stopping drinking, smoking and skipping the soda too.
And last, do some research on those people you are listening too (TV-Radio-Print), make sure they really know what they are talking about. A family friend is a world renowned expert... he also thinks the CIA is watching him through TV sets, the FBI would tap his phone, the feds know where he was if he had an ID Card, so he has no tv, phone, foil on the windows, no drivers license, a basement full of chili and rarely gets more than a few blocks from his house .....and yet people look to him for his knowledge on a subject UFO related. He might be a smart guy and read a lot, but is view of reality is limited due to his own fears.
