Scientists have documented the effects that a spacecraft and a submarine have on the passengers of these vehicles. The crews of spaceships and submarines already today experience a different mixture of the air they inhale. To understand the task at hand, we must first understand what a changing composition of the air we breathe does to our bodies. Can we evolutionarily adapt fast enough to the extremely rapid change in our environment caused by climate change? Simplistically speaking, evolution is the process of adaptation to the environment. During our evolutionary development, which resulted in us giving ourselves the title “sapiens”, translated to “wise”, we have experienced a very stable composition of the atmospheric composition. The same also holds for the evolution of us, homo sapiens.
Without change, there is no incentive to explore new radically different solutions. But the extinction events also drove evolution forward to new heights. From time to time, this change in the atmosphere caused extinctions. But life itself terraformed our planet into a habitable place for numerous lifeforms. The first atmosphere of our Earth was very much like that of Mars and Venus. To understand how life and our atmosphere are intertwined, we start by looking at our past. But how will our bodies and minds react to this change in the air that we breathe? The climate change talk mainly revolves around rising temperatures, more violent weather, melting glaciers, and rising levels of the oceans. How does our changing atmosphere affect the human body and mind? The direct impact of a changing atmosphere on humans and life, in general, is the central subject of this book.
