More public transport would be better for health and the life of cities, as well as reducing pollution and accidents. The failure of governments and business to act on climate change is due to their dedication to private profit, and also a very short-term view of issues. In the long term, climate change will cost many people their lives, make many more people's lives more difficult, and cost hundreds of billions of dollars. But for most business that is tomorrow's problem and they hope it won't come out of their profits. Yet again capitalism shows it is not interested in the well-being of people.
Climate change is one more reason for political change - for socialist policies.
