The new episode of "Superquark" opens with a BBC documentary from the series A Perfect Planet, titled "Man." We live, as we know, in a crucial era for the planet's climate. One of the main culprits is an invisible gas, carbon dioxide, or CO2. Nearly all modern activities produce it by burning fossil fuels. We release 100 times more CO2 into the atmosphere than all the volcanoes combined. This gas traps the sun's heat and raises global temperatures. And this destabilizes one of the planet's vital forces: the weather. Every additional degree generates extreme and uncontrolled phenomena, from droughts to devastating rainfall. And it affects the balance of life on Earth, causing the extinction not only of plants and animals, but also of our societies. Not to mention the impact we have on the seas and forests. What can be done? We must reverse these processes, globally.
