Cars are killing people and making the planet uninhabitable. Crashes take the lives of more than a million people each year. Air pollution linked to motor vehicles contributes to even more untimely deaths. Highways and unsafe streets have devastated cities, yet traffic congestion still swallows up countless hours. And carbon emissions from transportation are a key driver of climate change, which threatens to make the world unlivable. Why do we still worship at the altar of the car? How can we find alternatives that are healthier for the planet and ourselves?

The sky has always held significance for humanity, in both cultural and scientific terms. And yet we persistently pollute it with sometimes unnecessary light in our obsessive desire to chase away the darkness. This effectively switches off the stars, hampering our ability to enjoy one of the most inspiring sights nature has to offer to humankind. In addition, too much light is hazardous to both our health and that of the fauna and flora of this planet.

The scenario we are facing is scary: within a few decades, sea levels around the world may well rise by a meter or more as glaciers and ice caps melt due to climate change. Large parts of our coastal cities will be flooded, the basic outline of our world will be changed, and torrential rains will present their own challenges. But this is not the first time that people have had to cope with threatening waters, because sea levels have been rising for thousands of years, ever since the end of the last Ice Age.
