The Cosmos is vast, maybe more vast than the humble human mind can possibly imagine. Yet, as the celebrated scientist, Carl Sagan poignantly pointed out in his epic speech: this speck of cosmic dust, the pale blue dot that humankind call home is all that we have. So, we really ought to take good care of it.
“The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.” – Carl Sagan, Pale Blue Dot
Knowledge of our home planet and its place in the Universe is the fundamental basis of all scientific study. Topics and discussions centered on The Earth’s history and its progress are common in education. Now the big question is how our planet will cope with the impact of what we are doing to it. Climate change, pollution, species extinction, overpopulation… all are part of a long and worrying list of how human behavior is already destroying our one and only home.
The good news is that we know about it, and informed educators, leaders, and individuals have been raising awareness of these critical issues for decades. Change is happening: cities are restricting the use of cars, recycling has already become obligatory in some places, and more and more people are now choosing cleaner, sustainable, planet-friendly solutions for a great many everyday things from the food we eat to the clothes we wear.
Education is key to changing attitudes and behaviors. Here are some inspiring popplets on the subject.
