So, what are we doing to protect the health of our planet? Check out the UNEP (United Nations Environment Programme) Billion Tree Campaign here. And, while we’re on the topic, here is a wonderful list of facts and figures (compiled by Betsy Towner) from the April AARP Bulletin that provide some wonderful food for thought.
Our Stomping Grounds:
1. The planet is 4.5 billion years old.
2. Global warming followed each of several ice ages starting in the Precambrian time more than 600 million years ago.
3. 1.75 million years ago, ice covered all of Europe and most of North America.
4. 18,000 years ago, winter temperatures were 27 to 36 degrees cooler. Ice Age Florida was like Quebec.
5. As the India tectonic place pressures the Eurasian plate, Mount Everest is rising at 3 cm. a year.
6. Earth tilts 23.5 degrees on its axis, causing our seasonal weather variations.
7. More than 11 million species live on the planet.
8. Humans have named about 1.7 million.
9. Oceans cover 70% of Earth’s surface.
10. Forests harbor 80% of Earth’s biodiversity.
11. The last decade had the highest average temperatures on record.
12. Global temperatures may rise as much as 10.4 degrees by 2100.
13. More than 70 million barrels of crude oil are produced a day.
14. The 806 million cars and light trucks in the world burn 260 billion gallons of gasoline and diesel fuel a year.
15. 1.6 degrees: the rise in average temperature between 1970 and 2010.
16. Every square mile of ocean contains 46,000 pieces of plastic trash.
17. Extreme weather may force relocation of 150-200 million people by 2050.
18. Known species extinctions since 1500: 869.
19. Known species at risk for extinction today: 18,351.
20. Sea levels are predicted to be 3 feet higher in 2100.
21. Ocean temperatures have risen 1.4 degrees since 1970.
22. One-third of the oceans’ rise is because of higher ocean temperature.
23. In the last 8,000 years Earth has lost 11,000 square miles of forest.
24. Renewable energy provides 8% of total U.S. energy. Other sources: petroleum (37%), natural gas (25%), coal (21%), and nuclear (9%).
25. Sources of greenhouse gasses: electric power (35%), transportation (27%), industry (20%), agriculture (7%), commercial (6%), residential (5%).
In the Last 50 Years:
26. Since 1960, world automobile production has increased by 370%.
27. The U.S. share of auto production dropped from 47.9% to 4.6%, China’s grew from 1% to 21.7%.
28. The average price of a gallon of gas grew from 25 cents to $3.51.
29. The acverage cost of a new car rose from $2,600 to $27,958.
30. World oil consumption grew 401% from 21.3 million to 85.8 million barrels a day. U.S. consumption rose (up 198%), so did China’s (up 458%), Japan’s (724%), India’s (1,850%), and Germany’s (409%).
31. Average U.S. house size grew from 983 sq. ft. in 1950 to 2,377 sq. ft. in 2010.
32. Home size peaked in 2007 at 2,521 sq. ft.
Steps in the Right Direction:
33. The ozone hole is at it smallest since 2004, due to reduced chlorofluorocarbon usage.
34. It is predicted to disappear altoghether by 2050.
35. The average American accounted for 17.7 metric tons of carbon dioxide in 2009, down from 20.3 metric tons in 2005 (although still 4 times the world average).
36. Soot reduction, easy and cheap to do, could halt warming enough to preserve Earth’s polar ice cap.
37. Since 2001, the bald eagle and nine other U.S. wildlife species have bounced back from endangered status.
38. U.S. investment in solar power lowered the cost of clean, renewable energy.
39. Offshore wind farms: same story.
40. Biofuel could soon be used in jets fitted to fly on this lower-carbon source.
Easy Ways to Tread Lightly:
41. Buy better meat, but less often. Opting for cuts from sustainably raised animals and decreasing meat consumption will ease environmental stress.
42. Set your water heater at 120 degrees. Many are set at 140 degrees, which is both wasteful and hazardous.
43. Use your wood-burning stove or fireplace only on special occasions; the smoke pollutes both inside and outside air.
44. Reduce your time in the shower by 5 minutes and save 25 gallons of water a day.
45. Loading dirty dishes without rinsing saves up to 20 gallons or water per dishwasher load.
46. Add native plants to your garden; they need less water and fertilizer.
47. 90%: the amount of energy saved if you wash clothes with cold water.
48. If rain is coming, don’t water or fertilize your garden. Water will go to waste and fertilizer will travel down storm drains, polluting waterways.
49. Bank online to save paper. You’ll do it once then wonder what took you so long.
