A TV documentary I learnt a lot from The documentary from which I honestly learnt important things was about the climate crisis of our times. We have a lot to learn about climate change, about why it's happening and what that means. But one thing is clear: it's real, alright. Environmental challenges put into three categories, even called "local environmental problems": air pollution, water pollution, hazardous waste dumps. There are also "regional environmental problems", like acid rain (there are a lot of those). Naturally everything is affected, and we have to organize our response appropriately. We need a worldwide, global mobilization for renewable energy, conservation, efficiency and a global transition to a low-carbon economy. We have work to do. We can mobilize resources and political will. We have the capacity, at the moment of great challenge, to set aside the causes of distraction and rise to the challenge that history is presenting to us. As the documentary explain, everything is effected and everyone should be show interest for this big issue.
