Before And After: Global Environment Dramatic Changes

Human beings compete with other living things for resources and space. As the world’s population continues to increase, and standards of living improve, there is serious danger of a permanent change to the global environment.

Human activities have led to the pollution of the environment, and a reduction in the amount of land available for other animals and plants, which makes it difficult for some species to survive. There is a need to achieve a level of development that also sustains the environment for future generations.

NASA’s collection of photos contains a really powerful demonstration on how human beings changed the appearance of the planet within the years. If you compare few of these images where the time difference ranges from 5 to 100 years, you will see the incredible change:

Pedersen Glacier, Alaska. Summer, 1917 — summer, 2005.


Aral Sea, Central Asia. August, 2000 — August, 2014.


Carroll Glacier, Alaska. August, 1906 — September, 2003.

This is the greatest engineering project in the world: a network of pipes, aqueducts and wells more than 500 metres deep. The water system provides the desert area with water.

Qori Kalis Glacier, Peru. July, 1978 — July, 2011.


Mar Chiquita Lake, Argentina. July, 1998. — September, 2011.

Uruguay has managed to grow its forested area from 45,000 hectares to 900,000 hectares. However, this has had the effect of a loss of plant and animal diversity.
