Nothing quite shows change over time like a picture does. NASA has fully embraced this idea. The Association has gone ahead and made a gallery of before and after pictures displaying environmental changes of different areas, caused by climate change, urban growth, human impact and extreme. The idea is to express the rate of flux our planet is, but also to spread the awareness of human impact and climate change even though the galleries focus on other types of change as well. Nothing in this world is permanent.
