The world in chaos, suburban streets have turned to open landfills. Electronic waste has become so overwhelming that major electronics companies are getting shut down. 
It all started around 2020, People refused to recycle E-Waste as it was “too much of a hassle” or in some countries “too expensive”. Toxic waste slowly built up to the point where the ground was so polluted that all groundwater was ‘Hazardous’.
By 2030 most rivers and streams turned to toxic swamps filled with dead fish and mammals melting in the chemical slurry. Anything that came in contact with the water would almost certainly die. 
The latest fashion trend of 2040 is a coverall vapor hazmat suit. going outside without it is likely to kill you in minutes.
Almost all species are extinct now in 2050. Humans have been trying to undo the damages but the earth is too far gone. Anyone who had money has already left the planet on the 2045 SpaceX mission to find another habitable planet with their new XHyperDrive space explorer. Any humans unlucky enough to be left behind are left questioning where they went wrong, was it so hard to just drive to the nearest E-Waste Transport Center?
The remaining humans of 2050 have a big problem to solve should they have any chance of survival.
2040 - 2060 Clothing Trend:

In 2055 I design a robot that can perfectly sort Toxic waste into its raw materials. This robot goes around streams and rivers sucking up water and separating it into raw materials like metals, common alloys, chemicals, and water. The filtered water is then pumped back into the river. The result is an autonomous amphibious chemical categorizing thingamabob or The AACCT. an army of these should theoretically make the planet habitable around 2060 to 2070
