Humans have done a pretty good job leaving their marks on Earth. However, it's not always in a good way.
By capturing a series of photos over time, NASA has been able to reveal the magnitude of our human footprint, and you might want to brace yourself; these before and after images are seriously shocking.
Take one look at the damage we have already done over such a short period of time, and it's not hard to see we are changing the climate and destroying the world we live in at a faster rate than ever.
By creating this thought-provoking visual series, NASA hopes to raise awareness about the challenges of environmental conservation so we can preserve the planet for future generations.
Take a look at the pictures below to see these drastic before and after photos of Earth.
