Stefan's Big Question

Is the human race capable of avoiding self-destruction due to damage to our planet's "health"? We already experience the effects of global warming, which will affect each person living on this planet sooner or later. It remains to be seen whether we can avoid destroying our own planet, and there is no alternative to living on Earth right now. We should keep in mind that space is the most hostile of all environments and leaving Earth on a lifeboat is not an option.
