The day marks when humanity's annual demand on nature exceeds what our planet can renew in that year. This year, it falls on Aug. 1 - one day earlier than in 2017, which fell on Aug. 2, and the earliest since our planet went into "overshoot" in 1970, which fell on Dec. 29.
Five tonnes of plastic waste from the sea is transformed into a leaping 12 metre tall whale in Belgium's Bruges canal
