The Global Issue

A PowerPoint Presentation On Global Warming

By Clare Richardson

Global Warming is a “big” issue

• It has a large effect on the entire world.

• It is very relevant an important today.

• It is a multi-faceted problem.

The entire idea of global warming is the sum of many different

environmental issues added up together.

• The thinning ozone layer

• The greenhouse effect

• Increased emissions

The Thinning Ozone Layer

• Ozone is a molecule made up of 3 oxygen atoms.

• Found in the Stratosphere.• Prevents most Ultraviolet (UV) radiation from

reaching the earth.

Why is the ozone layer thinning?

• Human produced chemicals are destroying the vital layer.

• Example of these chemicals are halo carbons and chlorofluorocarbons (cfc’s).

• These chemicals are found in refrigerators, aerosol containers, and air conditioning units.

• Because of the production of these chemicals, more harmful UV rays are reaching the earth and raising its temperature.

• There is a huge concern about the thinning ozone layer, especially over the Antarctica, where there is a large hole.

• The hole is thankfully diminishing thanks to the world’s increased efforts to lessen production of harmful chemicals.

The Greenhouse Effect

• Greenhouse gasses are gasses that allow more UV rays to pass into the earth’s atmosphere, but prevent the rays from radiating back out.

• Carbon dioxide (left picture), water, and methane (right picture) are all greenhouse gasses.

The Greenhouse Effect

• Because the greenhouse gasses let more UV rays through and then trap the rays and prevent them from exiting, the earth’s temperature is rising.

Why Is the Greenhouse Effect Occurring?

• Since the Industrial Revolution, carbon dioxide emissions have greatly risen. (See next slide for graph)

• Emissions of other greenhouse gasses are also on the rise.

• Trees produce oxygen that removes carbon dioxide from the atmosphere, and because trees and forests around the world are being destroyed they are unable to eliminate Carbon dioxide at the same rate.

How YOU Can Help!

5 Easy Ways To Help Eliminate Global Warming

#1 Buy a Hybrid Car

• Hybrid cars produce less emissions than their regular counterparts.

• They are more fuel efficient than other cars.

• Because of new technology hybrids are more affordable than ever.

• Car companies like Toyota, Lexus, Honda, Ford, and Nissan all produce hybrid cars.

• Hybrids help save the environment and you money at the same time!

#2 Eliminate Junk Mail

• The average person receives 41 pounds of junk mail every year.

• Sites like Forty one pounds and Stop Junk Mail help people stop receiving useless junk mail

• By getting rid of junk mail, you save trees (vital to eliminating carbon dioxide) and time (no more sorting through the mail!)

#3 Recycle Dead Batteries

• Old, dead batteries clog landfills all over the world because they cannot decompose over time.

• Sites like Rechargeable Battery Recycling Corporation help people find local sites to recycle their dead batteries.

• Recycling batteries eliminates waste.

#4 Choose Reusable Bags Over Plastic or Paper

• Even though they are recyclable, plastic and paper bags are a huge waste because most people don’t recycle them.

• Cloth and other material bags are reusable trip after trip to the store.• Grocery stores like Trader Joes and Whole Foods give shoppers discounts

on their purchases if they bring their own bags.• Top designers like Anya Hindmarch (left), Stella McCartney, and Hermes

(right) all make reusable bags.• Reusable bags eliminate waste and are very stylish!

# 5 Turn It Off!

• Turn off lights in rooms if nobody’s there, and unplug appliances that are not in use.

• Some appliances constantly use electricity even when they’re not in use if left plugged in.

• By turning it off, you will eliminate electrical waste and save money!

By understanding global warming and learning how to reduce your

environmental impact, together we can help bring global warming to an

end!
