(1999-2001)
Accumulation in the atmosphere that in sufficient concentration, endanger
human health or other measured effects on living matter and other materials.

Plant a treeA single tree will absorb one ton of carbon dioxide over its lifetime.
Shade provided by trees can also reduce your air conditioning bill by 10 to 15%.
Use a clothesline instead of a dryer whenever possibleYou can save 700 pounds of carbon dioxide when you air dry
your clothes for 6 months out of the year
Be sure you’re recycling at home You can save 2,400 pounds of carbon dioxide a year by recycling
half of the waste your household generates.
Buy organic foods as much as possibleOrganic soils capture and store carbon dioxide at much higher levels than
soils from conventional farms. If we grew all of our corn and soybeans organically, we’d remove 580
billion pounds of carbon dioxide from the atmosphere!
Reduce the number of miles you drive by walking, biking, carpooling or taking mass transit wherever possible
Avoiding just 10 miles of driving every week would eliminate about
500 pounds of carbon dioxide emissions a year!
Eat less meat Methane is the second most significant greenhouse gas and cows
are one of the greatest methane emitters. Their grassy diet and multiple stomachs cause them to produce
methane, which they exhale with every breath.
Activity 1: PODCAST using AUDACITY
Instructions: Working with partner (2-4), create a digital recording that explores one of the topics below:
• The important facts about Global Warming
• The causes and effects of Global Warming
• Alternative methods and solutions on how to control Global Warming
Microsoft Excel Worksheet

on Podcast using Audacity
Procedures:
1. Each group will create a structure and script for the podcast based on the chosen topic.
2. With your partner identify several points you wish to include keep in mind that your podcast has a five – minute limit.
3. Deliver the podcast in a conversational style. You may work from notes or use a prepared text. But the delivery should sound conversational not like a text being read. Practice, record, listen and monitor your delivery on the recording. Record again.
4. You should edit out unwanted pauses or small errors.
5. When the podcast has been recorded to your satisfaction export the file. Windows users, Windows users choose File>”Export as MP3.”
Requirements:
1. Your podcast must be 4-5 minutes. Each person should speak approximately half the time.
2. Introduce yourselves in your group number at the beginning of the podcast and name yourselves again at the very end. Be sure to introduce the topic near the beginning of the recording. At the end give a brief summary and state your names again.
