Rumour has is that there are several bunkers in the world. Some date back to the Second World War. Some have been set up after that. The locations are classified top secret. They even have a protocol of who gets to go into the bunker. Just in case something catastrophic happens. A giant asteroid hitting planet Earth for example. Scientists would argue that we are more likely to destroy ourselves than have an asteroid do it for us, but that’s another matter.
Imagine something did happen. The key to survival would be the ability to eat. Humans do not do so well without food and water. Water stores; food not so well. People are designed to survive on fresh food predominantly. In the absence of, often you rely on canned foods. From canned soda, coconut milk to soups and vegetables they all come in canned versions. Cans are however lined with something called BPA or bisphenol A. This is the same BPA that is also found in plastic bottles, water bottles, etc.
The FDA says that at low levels, BPA is safe for consumption. However, it is probably safer to avoid BPA and source your food, soup or water fresh. Heat activates BPA; if you stick your water bottle in a microwave for example. The same process can occur if your plastic container is exposed to high temperatures during storage or transportation from factory to consumption. Experts, therefore, recommend using glass, porcelain or even stainless steel.
So imagine you are one of those lucky few chosen to be moved to the bunker. Or like in the movies, you were able to snatch your girlfriend from a crowd and somehow and drive her on your motorcycle into the cavern. Once you get there, the cans might get you. Not immediately but in the long run. It is probably wiser to pray that no asteroid hits our planet and of course that we don’t destroy ourselves prior.
