  • Hi everyone!

  • This is president Barack Obama.

  • NASA's Aura Satellite has been tracking global pollution trends for the past decade

  • and it's initial findings have shown us a lot about the state of our atmosphere

  • The satellite detects gases like nitrogen dioxide,

  • the common pollutant from cars and power plants,

  • the data shows us that the United States and Europe have some of the highest emissional levels in the world

  • But it also shows us that over the last 25 years,

  • Nitrogen Dioxide levels have dropped by up to 50% in both regions.

  • Thanks in large part, to new rules that protect our air.

  • At the same time, in China, India, and the Middle East.

  • This pollution has grown dramatically

  • So imagery like this can help us see what actions are working,

  • and where we need to focus additional international efforts.

  • and it proves, that we all need to work together

  • to protect the one planet we've got.
