— Environment and climate —
The Earth, a safe place to live?
The environment as a liveable habitat for humans is limited by what is described as the planetary boundaries. These are the conditions necessary to make and keep life possible and comfortable now and in the future. These include a certain concentration of atmospheric oxygen and non-acidic drinking water. Our metabolism and the food pyramid depend on these limits. If we consider ourselves important and if human civilization and all the wars already fought had any meaning or purpose, we would do well not to throw the natural equilibria too far out of balance. But these equilibria are now compromised, due to our too great impact on the environment. But knowledge is power, which can lead to action.
