The infant mortality decreased

This data entry visualizes how infant mortality decreased over the last 2 centuries. Visualize the data on a series of world maps if you want to study how infant mortality is now decreasing around the world. This fundamental change contributed to the rapid increase of life expectancy of people around the world. Before the onset of modernity every 4th child died before its first birthday. Over the course of modernity the mortality of infants (children below 1 years of age) declined rapidly – first in the countries that industrialized early and now in countries around the world. This is shown in the following time series plot. [source : Our world in Data by Max Roser )

Optimism for the Aral Sea ?

The Aral Sea is situated in Central Asia, between the Southern part of Kazakhstan and Northern Uzbekistan. Up until the third quarter of the 20th century it was the world's fourth largest saline lake, and contained 10grams of salt per liter. The two rivers that feed it are the Amu Darya and Syr Darya rivers, respectively reaching the Sea through the South and the North.

 The Soviet government decided in the 1960s to divert those rivers so that they could irrigate the desert region surrounding the Sea in order to favor agriculture rather than supply the Aral Sea basin. The demise of the Aral Sea in central Asia was caused primarily by the diversion of the inflowing Amu Dar’ya and Syr Dar’ya rivers to provide irrigation water for local croplands.

These diversions dramatically reduced the river inflows, causing the Aral Sea to shrink by more than 50%, to lose two-thirds of its volume, and to greatly increase its salinity. At the current rate of decline, the Aral Sea has the potential to disappear
However A new study using data from NASA satellite missions finds that, although the long-term water picture for the Aral Sea watershed in Central Asia remains bleak, short-term prospects are better than previously thought.
