Review NASA photos to see how terribly the Earth has changed

For years, humanity has left a huge impact on the Earth's environment and natural landscape.

NASA's satellite technology allowed them to store documentary images of the universe and the Earth from decades ago. Then at the beginning of 2017, NASA opened its huge treasure to become that "brand" openly for everyone to admire.

And with this source of photos, if you find it hard to find out, you'll collect photos that show the Earth's change after decades, as the new Bright Side authors do below.

1. Pedersen Glacier glacier (Alaska - USA) summer 1917 - 2005

Pedersen Glacier Glacier (Alaska - USA) summer 1917 and summer 2005. The difference is obvious after 100 years, when the amount of ice here is replaced by green grass due to global warming.

2. Carroll Glacier, Alaska Glacier (August 8, 1906 - September 2003)

Similarly, the Carroll Gracier glacier also has a significant change of meat compared to 100 years ago. And the reason is still only one - climate change.

3. Bear and Alaska glaciers (January 7, 1908 - August 2005)

4. McCarty Glacier Glacier, Alaska (January 7, 1908 - August 2004)

5. Toboggan Glacier Glacier, Alaska (6/1909 - 9/2000)

6. Aral Sea (Central Asia) 8/2000 - 8/2014

Within 14 years, the Aral Sea has shrunk, and there is a risk of missing on the world map
Aral is a Central Asia enclosed sea, not connected with other seas but still maintains the concentration of salt that is compatible with the ocean. What supplies water to Aral are the surrounding rivers - like Amu Darya and Syr Darya.

Things have changed since 1930, when the neighboring government decided to dig a canal for irrigation in the desert. By 1960, the Aral Sea lost supplies of 20 to 50 billion cubic meters of water, leading to gradual shrinkage.

From the world's fourth-largest sea, Aral is shrinking, and it will evaporate completely within the next 10 years.

7. Oroville Lake, California (7/2010 - 8/2016)

Oroville Lake area was once a "fairy scene" for activities such as sailing, fishing, relaxation . But then the historic drought lasting up to 5 years since 2010 has made the lake almost dry. , area narrowed to more than 2/3.

According to meteorological experts, drought occurs due to the influence of El Nino.

8. Lake Powell in Arizona and Utah (March 1999 - May 2014)

9. Lake Mar Chiquita, Argentina (July 1998 - September 2011)

As one of the largest saltwater lakes in South America, time is also quite cruel to Mar Chiquita Lake. The area of ​​the lake is shrinking - mainly due to climate change and the process of encroachment by local people.

10. Matterhorn mountain of Alps range (August 1960 - August 2005)

At the same time of year, the amount of snow and ice at the top of the Matterhorn (the Swiss and Italian border) is completely different - a clear consequence of climate change.

11. Rondonia Forest, Brazil (June 1975 - August 2009)

Consequently, after decades of human destruction of forests, taking agricultural land in Brazil.

12. Forest of Uruguay (March 1975 - February 2009)

Unlike other countries, Uruguay sought to expand its forest area - from 45,000 hectares to 900,000 hectares.

However, due to mainly using human crops, this process greatly affects the biodiversity of the forest.
