No Blade of Grass (1970)

http://www.imdb.com/title/tt0066154/

I was twenty, straight out of high school when I watched this environmental movie. It had molded my thinking. I am a staunched thinking of keeping the world in it's natural form. Hence in my books, Mail Order Bride I wrote about saving beached whales, I wrote about saving beached whales. It is very sad to see whales coming to the beach and die.

Storyline

A strange new virus has appeared, which only attacks strains of grasses such as wheat and rice, and the world is descending into famine and chaos. Architect John Custance, along with his family and friends, is making his way from London to his brother's farm in Scotland, where hopefully, there will be food and safety for all of them. Along the way, they encounter hostile soldiers, biker gangs, and all manner of people who are all too willing to take advantage of travelers for a mouthful of food.
