Familiar sight..?500 billion plastic bags distributed annually worldwide , and less than 3% of those bags recycled.They are typically made of polyethylene and can take up to 1,000 years to biodegrade in landfills that emit harmful greenhouse gases. (Time, 2007)

Human health hazard
Phthalates, a chemical used to make plastics pliable, may have hormone disrupting effects on unborn baby boys; also linked to obesity and diabetes in men ( CBC News (2008), URMC Press(2007))
Enters food chain as it is ingested by sea and land animalsFor more negative health effects, see http://www.ecologycenter.org/factsheets/plastichealtheffects.html#plas tichealthgrid Contd.

Plastics in land fills emit greenhouse gases which trap heat and contribute to Global
Warming (GW)

Global Warming and Consequences • Ice melting - includes mountain glaciers, ice
sheets covering West Antarctica and Greenland, and Arctic sea ice
• Researcher Bill Fraser has tracked the Decline of the 7 April 2009 penguins on Antarctica (from 32,000 breeding pairs to 11,000 in 30 years)
• Movement of butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas
• Precipitation (rain and snowfall) has increased across the globe, on average.
• Sea level rise became faster over the last century

“We now know without a doubt that global warming is threatening us with higher temperatures, more drought, more wildfire, more flooding, and more erosion of our coastal communities…the overwhelming scientific evidence has proven this over and over again. We must act now with the rest of the world to curb emissions” Barack Obama, President, US
