Ecologists are the scientists that gather information on the “household” Earth, from the micro to macro levels through the disciplines of biochemistry, molecular biology, and cellular biology, as well as the sciences of anthropology, botany, zoology, geology, and the study of local ecosystems to the global biosphere.
Environmentalists address the negative aspects of human activity such as climate change, conservation, energy, land degradation, over-population, pollution, resource depletion, sustainable development, and waste, on the biophysical environment through advocacy, education and activism.
The “Green” political movement addresses the ecological problems through grassroots, participatory democracy and is deeply related to peace and justice, non-violence, and feminism.
“Suddenly, from behind the rim of the Moon, in long, slow-motion moments of immense majesty, there emerges a sparkling blue and white jewel, a light, delicate sky-blue sphere laced with slowly swirling veils of white, rising gradually like a small pearl in a thick sea of black mystery. It takes more than a moment to fully realize this is Earth . . . home.” Astronaut Edgar Mitchell
“Once a photograph of the Earth, taken from the outside,
is available, a new idea as powerful as any in
history will be let loose.” Astronomer Sir Fred Hoyle, 1948
