Understanding Political Feasibility

In the present, we find industry engaged in factory farming on a massive scale, resulting in the torture of a great number of animals; we find many nations with nuclear weapons, resulting in the constant possibility of nuclear warfare; we find sea levels rising rapidly due to climate change, with the result that low-lying nations are at threat of being completely submerged. We might ask: 'is abolishing factory farming feasible?' 'Is universal nuclear disarmament feasible?' 'Is a radical reduction in the global concentration of greenhouse gases in the atmosphere feasible?' We do not know the answers to these questions, but we can make more or less educated guesses. This is an article about those more or less educated guesses. Adapted from the source document.
