Plastic is not inherently evil. In fact, when used properly it's a useful and lifesaving material. The problem right now is terrible design - items we use for a few seconds, made out of a material which can last forever...

4 billion used per year in Australia alone. 

17 million barrels of oil used to make plastic bottles annually.

1 million disposable cups into landfill every minute.

Used for a minute, made of a material which may last forever.
