Before and after: 9 impactful aerial images show Earth changes

That the earth is constantly changing you are bald to know. But as we usually live in our little world, we hardly have a sense of how impactful these changes are, even in a tiny space of time.

NASA recently released a series of satellite imagery showing that population growth, climate change and other factors have helped radically transform the earth's crust. And nothing better than seeing the world from above to get a real sense of the impact of these changes on the planet. Check it out:

1. Lake Urmia - Iran

In a span of just 3 months, the lake has shrunk in size and has changed its color from green to brown due to the proliferation of some types of algae and bacteria that grow a lot in the summer. In the last 14 years, 70% of the lake area has disappeared.

2. Great Salt Lake - USA

This lake is located in the state of Utah and had a drastic reduction in size between 1985 and 2010. This is a result of the decrease in rainfall in the region and the low melting of the mountains that feed the streams that flow into the lake.

3. Owens Lake - USA

Located in California, this lake was one of the most important migratory bird stops during US travels. However, the diversion of the Owens River into a Los Angeles aqueduct caused the waters of the lake to dry up dramatically. What remains still suffers from contamination of chemicals and toxic dust.

4. Baban Rafi Forest - Niger

In the 40 years leading up to the 2007 image, the population in this region of Niger quadrupled, causing large chunks of the forest (darker green) to give way to agriculture.

5. New Delhi - India

In 25 years, the population of the Indian capital and its metropolitan region has jumped from 9.4 million to 25 million! While population growth complicates public administration, it also impacts the environment and various factors that determine the quality of life.

6. Greenland

It is normal for lakes and rivers to appear on the icy Greenland plain each summer. However, in 2016 this thaw began much earlier than normal, causing changes in the landscape and even sea level.

7. Greenland

Other images from Greenland show the shrinking of the Helheim glacier within 4 years. The size of the glacier remained constant between the 1970s and 2001, when it began to retreat rapidly.

8. Ganges River - India

The torrential monsoon of 2016 caused the level of the Ganges to rise sharply, causing flooding and killing approximately 300 people. In addition, more than 6 million Indians were affected by the river flood last year.

9. PoopĆ³ Lake - Bolivia

Bolivia's second largest lake dried up in 2016. This is not the first time this has happened: in 1994, this had already occurred due to diversions of its water sources for mining and agriculture. PoopĆ³ Lake took years to restructure, causing a major impact on the region's ecosystem.
