Mr Spikester hits in on the head. Most governments such as UK, France, Canada said they're will always be enough supplies of food and all but stupid Tom, Karen and Barry think we are all going to die. I blame some media for it, espeallity clickbait like the two below.
"Oh my God we're all going to die!" Barry and Karen scream as they run down to Tescos if British, Walmart if American, Woolworths if Australian or Loblaws if Canadian after seeing the big scary text.
I think most people are just idiots and ****ing too dumb to be level-headed.
