Our world is an ever-changing complex system. As Software Engineers, we are uniquely aware of how even the smallest change in an input can have far-reaching consequences in a system that is built up from many components. Even if we are unaware of our exact impact, you can safely assume that almost anything you do in life has an effect on something.

In the decades preceding this book, a growing fraction of people have come to understand that we have been rather consistent in manipulating some of the inputs of our Planet's various systems. The current outlook on the consequences of these actions have many people feeling uneasy, or even fearful of the future. As global temperatures are rising, weather patterns are changing and even social tensions are rising, many people have already started wondering \"What can I do?\".

This book before you is the result of a group of people from the global Java Software Engineering community, who were all looking for a way to contribute to a more sustainable world and work on creating a future for generations to come. Many of them were already involved in various initiatives to raise awareness or educate software developers to their role in the transition to come.

Through the magic of the open Foojay community, they have been able to find each other and bundle their efforts into this book.
