What should people learn to survive in the harsh climate? Remember that science could influence the educational level of the public because people tend to forget those unimportant stuff (e.g. literature, gender study, etc.) Be careful with mentioning gender study, you might offend people What skills beside STEM subjects are required? Math, physics, and chemistry were required, but biology was not that important. Most species went extinct in the 21th century, so it was less important for people to research ecology and genetics. Still, a lot of scientists were trying to research genetic editing both for humans and vegetation, so that they could manage to survive under harsh environments without protection, even though the only crop which could survive outdoors was the rice. People also had to learn about how to locate water outdoors. They could locate water underground by investigating the properties of soil and stone. They could also build webs collecting water with straw and wooden sticks. Most people also knew about how to build traps to catch wild rabbits or mice. Basic survival skills such as building shelters, fighting sandstorms and drilling wood for fire were also required. All of these survival-craft skills were contained in the obligatory education system provided by the country.
