By refusing to use plastic bags, you can make a huge difference to the pollution problem. Remember that each person uses about 83 bags a year. If there are four people in your family, that's 332 plastic bags less every year.
That's 332 bags less that will:
Release toxins into the ground water from landfill sites
Stay in the environment for hundreds of years while they break down
Get into the food chain through animals that ingest small particles of plastic
Waste energy during the manufacturing process
Kill any of the estimated 100,000 marine animals that die each year of plastic pollution
These are all-important factors that have a profound affect on our environment and the creatures we share our planet with. Should we really put our own selfish needs before the needs of everything around us now and the lives of future generations? That's up to you to decide.
