In 1968, Williamn Anders took what has been described as the greatest environmental photograph of all time while venturing farther than any other human had travelled before aboard the Apollo 8 spacecraft. He was orbiting the Moon when a half-illuminated slice of our home planet suddenly emerged beyond the lunar horizon.people called that photograph Earthrise.
In the 19th century, Tomas Moran's painting from a, little-explored comer of Wyoming helped to inspire US President Ulysses S Grant to create; Yosemite National Park. His description of what Carl Sagan later described as our pale blue don't far out there in space, was an artwork that had relevance to everyone.
the 52 years that have passed since Earthrise was taken, the humans on that little speck in space have increased the concentration of carbon dioxide in their atmosphere by almost 30 per cent, wiped out 60 per cent of its mammal; bird, fish and reptile populations, and now teeter on the brink of environmental catastrophe.
Perhaps the result justified the carbon-intensive means, but what about today's explorers? What expectations and values should we place on modern-day adventurers as they travel and return, often with stories from our last remaining wildernesses?
A. Impressed deeply by the splendid scene, Anders never forgot it in his life.
B. This wasn't the first time that art had proved to be an important tool for environmentalists
C. Grabbing his camera, Anders captured the image that later moved the world.
D. Yet, while Yellowstone, the world's first national park, today enjoys a little of protection, our planet is in serious trouble.
E. Though Yellowstone still exists, people ignore our planet.
F. But Anders' adventure on Apollo 8 went beyond national boundaries.
G. A lot of CO2 was produced when Apollo 8 was launched into orbit.
