There is no green energy. Nor pink, nor black. Nor clean nor dirty, for that matter. In this intelligent, eye-opening and witty bestseller, an eminent climate expert takes a graphic novelist on a journey to understand the profound changes that our planet is experiencing. The scientist, Jean-Marc Jancovici, explains the workings of superpowers and history; oil and climate; ecology, economics and energy flows. He describes, in short, the world we live in today-a world whose future is deeply uncertain. The artist, Christophe Blain, intently listens and draws. As the pair come face to face with global warming, they - along with Mother Nature, Pop Eye and Jiminy Cricket, among others - create a picture of what the solution to our predicament actually looks like. It's not just about switching to renewable energy sources, they show. It's about rethinking everything: our energy supply, our economies and our whole world. We're left with a vision of the future in which food, education, housing, transport and communities - in other words, all of us - work together and, with a few technological fixes, succeed in creating a world without end.

No matter how careful we are at using metals in industrial processes, some level of human exposure is unavoidable. Countless metals are obtained through mining and smelting activities that amplify their distribution throughout the environment. Applications of metals in industry, medicine, and agriculture have increased our exposure. These metals are not merely an occupational hazard for those working with them-they affect consumers and anyone exposed through environmental contamination. Even worse, they cannot be destroyed and are thus non-biodegradable. The blades we use, the pots and pans we cook with, children's face paint, and facial makeup contain toxic metals. Toxic heavy metals are also found in cigarettes, gourmet foods such as seasonings, fish, and chocolates. When you sprinkle a dish with Himalayan sea salt, you may end up ingesting toxic metals such as arsenic, cadmium and lead.
