started presentations
first is taylor jordan and dustin on deforestation:
deforestation-mass cutting down of trees from a certain area
causes-ag and cattle raising, dams and mega projects, fires, logging, mangroves and shrip, farming, mining, oil and gas, plantations
industries need more room so they chop down the forrest
poverty can also be a cause-the rain forrest is a huge oppertunity for making money and so they take the chance.
environmental effects-
plants, animals, and micro organisms can't survive without the forest which could lead to species destruction
soil erosion
people that live in the forest depend on it and can't live without it.
climate change-
when the trees are chopped down the moisture is evaporated into the air and the soil goes bad.
without the trees there is no shade to cool the ground and the temp dramatically rises
the water is dried up and it goes into a drought
social-
the forest is home to many tribes and people
when people chop the trees down there are many arguments
solutions-
many countries have started reforesting and some have over come deforestation
there have been strict laws set on the number of trees that can be removed
wildlife santuaries have been set up to save wildlife from deforestation
the way common people can help is become more environmentally friendly and use less tree products.
recycling
then ashlee mariah and kenzie went with climate change
climate change/global warming-long term significant change in the climate of an area-could be change in the temp or weather patterns
effects
rising sea levels
decreased snow in western hemisphere
arctic shrinkage and arctic methane releases terrestrial carbon from frost
heat waves
worsening droughts
stronger hurricanes
water shortage
food production will be effected because of the shifts in temp and rain fall
people's access to food by lowering income from costal fishing-rising sea levels
examples of effected areas
darfur-no land for farming
gulf coast- hurricane katrina
italy-disease outbreak
north europe-fruit becoming richer
australia-forest fires
caribbean-warmer seas more hurricanes
kyoto protical-an amendmant to the un frame work convention on climate change
bush promised to reduve carbon dioxide emissions
an international treaty intended to bring countries together to reduve global warming and to cope with the effects of temp changes
now:
165 cities voted to support it
supposed to happen by the end of the 21st century
"much of the debate over global warming is predicted on fear, rather than science"senater james inhofe
2007 was the year people started recognizing global warming
scientists think that its humans fault
presentation will continue tomorrow
