It’s not just cars. It’s plastic bottles. It’s CDs and DVDs and records. It’s paint. It’s film. It’s diapers. And thousands of other products.
If you want to make a difference, walk or ride a bike. Stop buying bottled water. Never, ever let anyone put your purchased products in a plastic bag. If you want to punish the oil industry, use less of their product. Giving your money to Exxon instead of BP doesn’t change anything.
Shop local. Bring your own bag. Carry your own water bottle. Re-use. Recycle. Walk. Thrift. Vote with your dollars, every day, every time.
