From an national level banning of plastics would go a long way into reducing their efffects on our oceans and land-use.
At the economic level (manafacturing) can khaki bags be manufactured and used, imagine having bio-degradable forks and knives at fast food outlets
And at an individual level being environmental stewards and knowing that our actions hurt the environment, and eventually we will be the ones to suffer in the long run, as for me i use disposable bags for shopping, i don't buy bottled water i refill the one i have.
