This beautiful, artistic video discusses Carl Sagan’s image and how he used astronomy to get across humanitarian and environmental messages.
The universe is humbling. To realize the immensity of the universe is to recognize that the earth is just a speck of dust in comparison. From a humanist perspective it sheds light on the fact that all the wars, conflicts and land disputes are over just a fraction of this speck in the universe. Is it all really worth it?
From an environmentalist perspective, earth is the only planet discovered thus far that can hold life. It is our home. Despite our differences, whether they be cultural, religious, ethnic, geographic or otherwise, we all share this speck of dust in our universe. Yet, we seem to treat our home as if it were indestructible. We exploit its resources, create mountains of trash, and pollute the air, water and soil that provide us with food and water to survive. We use the earth’s precious resources like they will always be available to us, and we treat those we share our home with like strangers, as if there is no common ground that unites us.
