km squared (3x size of France)
Weighs
80,000
tonnes estimated (
500x
Boeing 747s)
Affects
700
Species (Kills up to 100,000 animals a year)
1.8
billion individual pieces of plastic.

is recycled properly.
Plastic
and
useless
metals are burnt to find valuable metals, creates toxic fumes that affect areas for miles in all directions.
One of the largest food markets is located in the area, intoxicates food.
One egg exceeded safe limits on
chlorinated
dioxins by
220x.
150,000
tonnes of e-waste are imported into Ghana yearly.
Cape Town, South Africa (Day Zero):
Day Zero was the point where water rationing would be introduced, and mains shut off.
In October 2019, dams were up to
60
% lower than in 2018.
