only 10% of Aral sea remains in 2007
more than 50 miles away from locals homes

Environmental Catastrophe
dying of the aral sea has led to increase salinity levels in agricultural soils
cotton monocultures led to toxic pollution due to pesticides (DDT) sprayed over villages and cotton field workers
local climate change has increased temperatures, there's less rain and more desertification
150,000 tons of toxic chemicals have contaminated the water in the last 10 years
has led to polluting the soil and water supplies
water quality has reduced fish numbers
most water sources in Karakalpakstan are polluted
caused mainly by agro-industry and mining industries
Northern Karakalpakstan schools/hospital have no access to safe drinking water
in the past 40-45 years they've been using mineralized and polluted drinking water
Socio-Economic Issues
A prosperous industry which oncle employed 60,000 people in all villages has collapsed
unemployment and economic hardship are everywhere
health problems caused by wind-blown salt and dust from the dried out sea bed
pollution due to weapons, testing, industrial projects, pesticides
infant mortality is very high. 10% of children dying in their first year
upto 10 million people may be forced to migrate and become environmental refugees
