The Earth Is Green


PicSpeed -1754111663

In our everyday life we deal with problems that impact not only us but every living thing on this planet. Science and technology go a long way in helping us solve these issues, but mankind has been busy thriving throughout Earth’s history and we have not been that picky about what we leave behind.

Be it wars over Earth’s resources, bad laws made by governments, the thirst for oil, terrorism, religion or bad choices by every single one of us, one thing that never changes and we can always count on so far is what’s beneath our feet. Terra-firma, and the Earth is green.

We are so lucky to be able to go outside under the big blue sky with cotton candy clouds and roll in the grass. Even having hay fever can’t be all bad, because pollen in the air is at least a sign that nature is working away, green plants are propagating and honey is being made.

We have fresh air to breath as the green plants busy themselves taking in carbon monoxide and expelling oxygen. There’s humidity in the air and the clouds are busy collecting it. When they become too heavy they release that moisture, growing more green areas on the planet and bringing precious drinking water to the surface and the life forms waiting below.

The third rock from the sun is a planet like no other in it’s class it’s one of a kind. It’s a jewel in space and like all things that are one of a kind one day it will become extinct. Scientists agree this will happen at some future date unless our star (the sun) dies or another catastrophe befalls us. Terra and all life on it is connected like a spider web. The web is woven and intricate and one day a strand is broken. Only one strand…

What we don’t consider seriously enough is that one strand is connected to other strands all over that spider web and if enough of them break, or a major part of the web is gone, that web will eventually weaken and fail.


Take a few seconds to consider this awesome animated Gif from NASA’s achieves of Earth. Doesn’t it fill you full of raw emotion? But it’s what you don’t see that makes it so important. That’s because like the astronauts (just not live) you are experiencing a representation of what it would be like to see the Earth from space and to experience The Overview Effect for yourselves.

Although 75% of the planet is a relatively unchanging ocean of blue, the remaining 25% of Earth's surface is a dynamic green. Data from the VIIRS sensor aboard the NASA/NOAA Suomi NPP satellite is able to detect these subtle differences in greenness. This video highlights our ever-changing planet, using highly detailed vegetation index data from the satellite, developed by scientists at NOAA. The darkest green areas are the lushest in vegetation, while the pale colors are sparse in vegetation cover either due to snow, drought, rock, or urban areas. Satellite data from April 2012 to April 2013 was used to generate these animations and images.

The Earth is green and green means go. As long as the surface remains a “go” it’s reassuring. However NASA has been releasing animated Gifs showing deforestation and de-greening of the Earth. Melting of the Polar Ice, glaciers and slash and burn agriculture.

Man’s puny reach outside of our solar system has brought many discoveries although many have yet to be proven or understood.

Although we think we have found other “earth-like” planets, these planets are still a far cry from the resources we have on our own planet and man’s dream of finding another planet to colonize is still just that.

The Overview Effect refers to learning firsthand, the reality of the Earth in space from the astronaut's point of view.Thanks for stopping by; your comments are greatly appreciated and may your view be an Overview.
