The Bombing of Hiroshima and Nagasaki
Hiroshima and Nagaskai 1956
The United States detonated two nuclear weapons over the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively.
Hiroshima
Hiroshima was chosen because it was a military base and an industrial city. It had also not been touched during the war
Location
Nagasaki
Nagasaki wasn't the original city that was chosen, it was Koura
Impact
These bombs were intended to cause Japan to surrender to the allied forces and to bring about the end of WWII. As a result of direct exposure to these bombs, over 200,000 people died.
Impact
Although Hiroshima and Nagasaki are credited for steering the world away from nuclear war, since 1945 U.S., Russia, UK, France, China, India, Pakistan and North Korea have collectively conducted around 2,000 nuclear weapons tests.
Flint, Michigan Water Crisis
The Flint water crisis is a public health crisis that occurred beginning in 2014, after the drinking water source for the city of Flint, Michigan was changed. In April 2014, Flint changed its water source from treated Detroit Water and Sewerage Department water to the Flint River.
Flint,
Michigan
2014
Why is this happening
In order to save mney, the government wanted to alter the way people got their water source. In 2014, while the pipeline was under construction, the city turned to the Flint River as a water source. Soon after the switch, residents reported changes to the water's color, smell and taste.
Significance
The harmful effects of lead exposure on children's health are well-documented. They include cognitive deficiencies, increased antisocial behavior, lower educational attainment, and a host of problems affecting the brain, kidneys and liver.
About 41% of the 100,000 residents who live in Michigan exist below or at the nation’s poverty line which makes this a socio-political issue as much as it is an environmental one.
