1. The Power of You “ Global Warming” THE LOS ANGELES COUNTY UNIVERSITY LEARNING SERIES

2. We have been given an amazing gift .

3. Earth .

4. We have been given the opportunity to live amongst the earth’s beauty…

5. … and its natural resources.

6. It is a planet known for its ability to create and sustain life .

11. But today, much of the world has evolved into a modern era of technology and industrial growth

13. its human population growing exponentially.

17. Gridlock traffic

18. Massive Factories

19. Air Pollution

20. Earth has evolved into a very different place.

21. We are now faced with a serious problem

22. that affects you, me, our children

23. and future generations of people from all over the world.

24. It is called Global Warming

25. and we are responsible.

26. What is Global Warming ? It is a general warming effect felt on Earth’s surface, produced by greenhouse gases . A general warming effect felt on the Earth’s surface produced by greenhouse gases.

27. Primary Greenhouse Gases Carbon Dioxide released from burning coal, oil and natural gas in power plants, cars, factories, etc. Methane released from both ends of cows, rice paddies, rotting garbage in landfills, mining operations, and gas pipelines. Chlorofluorocarbons (CFC’s) released from air conditioners, refrigerators, sprays, pesticides, perfumes, paints, and aerosols. Nitrous Oxide released from artificial soil fertilization, the burning of fossil fuel, and livestock manure.

28. These gases and other air pollution collects in the atmosphere like a thick blanket, trapping the sun’s heat causing the planet to warm .

29. We have already begun seeing the troubling effects of global warming with unusual climate changes and extreme weather conditions.

35. “ How do greenhouse gases get into the air ? ”

37. When our massive and ever-increasing population performs these daily functions, electricity is used.

38. Electricity comes from power plants.

39. Most power plants burn coal and oil to create electricity

40. Which produce greenhouse gases.

41. Also, consider this…

42. There are countless greenhouse gas producing factories around the world that make the things we buy and use everyday.

43. Even the animals we raise for dairy and meat products release greenhouse gases into the environment.

44. All the trash we send to landfills around the world produce greenhouse gases.

45. It is important to know the Greenhouse effect is necessary. Without it, the Earth would not be warm enough for humans to live.

46. However, if we continue to increase the amounts of greenhouse gases into the atmosphere, the Earth’s temperature will likely continue to grow warmer

47. causing serious problems for plants , animals and humans .

48. “ The Effects on Our Ecological Systems ”

49. Many places on Earth depend on a delicate balance of rainfall, temperature, and soil type.

51. All living things rely on these factors.

53. Some scientists believe if future climate changes continue as they have, plants and animals may not be able to react quickly enough to survive.

57. “ The Rise of the Sea Level”

58. Warmer weather makes glaciers melt adding more water to the ocean.

61. Warmer temperatures also makes water expand creating higher sea levels, causing devastating flooding.

64. Thousands of small islands are threatened by the projected sea-level rise for the 21 st century.

66. Coastal flooding also may reduce the quality of drinking water.

68. “ The Effects on Our Crops and Food Supply”

69. Climate change may bring serious droughts to places where we grow crops.

72. In some parts of the world, people may not have enough to eat because they cannot grow the food they need.

76. “ The Effects on Human Health”

77. Climate change affects our health both directly and indirectly.

78. Heat stress and other heat related health problems are directly related to very hot temperatures and high humidity.

80. Ecological disturbances such as wildfires.

83. Poor air quality due to pollution.

86. Generally, poor people and poor countries are less likely to have the money and resources to cope with preventing and treating health problems.

89. So how can we make a difference ?

90. Reading - Learn about the environment.

91. Discussing global warming with family and friends.

92. Use less energy and reduce air pollution by carpooling.

93. Save energy by taking the bus, riding a bike, or walking.

94. Save electricity by turning off lights, the television, and the computer when done.

95. Planting trees absorbs carbon dioxide, a greenhouse gas, from the air.

96. Recycling cans, bottles, plastic bags, and newspapers sends less trash to landfills saving natural resources.

97. Buy energy efficient products . Many products with the Energy Star label are made to help protect the environment.

98. Buy recyclable products. They are usually made out of things that have already been used. Look for the recycle symbol .

99. Consider solar energy – Energy that comes from the sun . Solar energy can be used to heat homes, buildings, and to make electricity.

100. Consider environmentally friendlier cars. Some cars are better for the environment travelling longer on smaller amounts of gasoline or alternative sources of fuel.

101. Encourage our political and business leaders to be stronger supporters of environmental issues promoting new, innovative solutions.

102. Global warming is real.

103. The issue is what are we going to do about it ?

104. The problem is our responsibility.

105. The climate system may take a long time to respond to our changes,

106. but every day we can begin to do the little things

109. That help produce positive changes to our atmosphere

110. and have enormous benefits for future generations.

113. Our environment.

114. Our atmosphere.

115. Our future.
