30% of our trash is plastic packaging
Packacing can represent the 13% of the cost of an item
Packaging and marketing  overpacked products

17. Overpacking

18. Slow biodegradation Product Time to biodegrade Paper 2-5 months

Plastic bags
500 years - forever

19. Great Pacific Garbage Patch
A gyre of marine litter that extends over an area larger than twice the size of Texas
A hundred million tons of floating trash
Chain food
Photodegradation + plastic  toxic chemicals  jellyfish  larger fish humans

21. Risks
Pollution
Toxic chemicals like bisphenol- A (BPA) are endocrine disruptors (1930)
BPA is in plastic food packaging, plastic water bottles, canned foods, toys and even kitchen appliances like coffee makers.
BPA use is banned in baby bottles in European Union since September 2010

22. Reduce packaging waste
