I started preparing two years ago with purchase of seeds as well as saving seeds from my own garden. I also bought a freezer and developed a 90 day food supply centered around 12 go-to meals that I knew we liked to eat. Last but not least, I purchased a power station for power outages in order to keep my freezer running. Its the minimal amount of prepping needed to help see us through the impact of climate change on our degrading infrastructure.
