A continuación, un resumen en inglés. Free online access to the Wolfram|Alpha computational knowledge engine:answer questions; do math; instantly get facts, calculators, unit conversions, and real-time quantitative data and statistics; create plots and visualizations; and access vast scientific, technical, chemical, medical, health, business, financial, weather, geographic, dictionary, calendar, reference, and general knowledge-and much more.

"No country in the world currently meets the basic needs of its citizens at a globally sustainable level of resource use. Our research, recently published in Nature Sustainability (and summarised in The Conversation), is the first to quantify the national resource use associated with achieving a good life for over 150 countries. It shows that meeting the basic needs of all people on the planet would result in humanity transgressing multiple environmental limits, based on current relationships between resource use and human well-being. The chart below demonstrates the profound challenge nations currently face. National performance on seven environmental sustainability indicators is plotted against eleven minimum social thresholds for a good life (see About page for further details). Ideally, nations would be located in the top-left corner with no biophysical boundaries transgressed and all minimum social thresholds achieved."

"Hardly anyone seems to have noticed that the newest climate science suggests we are about to pass the point of no return, to unstoppable, catastrophic global warming. This short animation explains the positive feedback mechanisms that mean the Earth's climate system has a tipping point, followed by a brief glimpse into the crystal ball of horrors that will almost certainly come to pass if we cross it. Finally, the film explores how we got into the mess we're in, and the possibilities still open to us to prevent the worst natural and humanitarian disaster in human history, and the very real possibility of the end of civilization, and of life as we know it."
