I read a lot about how fragile our eco-system is but it seems to be sustaining. I mean, when things start to become scarce in grocery stores is when i'll start to worry. I've been reading about how bad the sardine population is in the oceans for years yet they are always in stock. I've been reading about the honey bees dying for years yet the store is flooded with awesome honey all year round. When the hell are we gonna have to start to worry about food and water?
