500 billion plastic bags distributed annually

12. 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

14. Global warming – A Reality –
World speaks…
“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,
02/14/13 President, can make a difference!

Why go far…Just recall the last
time we remarked or discussed
about the climate change in our
