Finished with our presentation, now waiting for Dotzler to correctly hook up his laptop so we can watch their presentation.
Zach's groups topic is Deforestation
The world's forests are in danger.. 15.5 million hectares of forest are deforested a year.
Every minute 150 acres of forest are lost. D:!!!!!
animals of the world's forests are in great peril.
monkeys are in danger nooo!!!!!!!!!!!!!!!!!!!!!!
effects of deforestation - dramatic effect is loss of habitat for animals, it drives one of the most controversial issues in the world - climate change...
solutions - reforestation can help, protecting endangered forests that are still left will also help, possibly making a change in laws such as to make cutting trees in a forest down a major crime can be helpful.
sanctuaries can help save forest even more.
- remember that the forests of the world are in trouble.
now doonan's
climate change
what causes global warming?????? - carbon dioxide contributes about twelve percent of the greenhouse effect, while water vapor causes thirty six percent of the greenhouse effect. methane causes five to ten percent of global warming, while ozone makes around three to seven percet of greenhouse effect posssible. solar variation?
effects? number five - spread of disease, when northern countries warm up, insects with disease may migrate north, bringing a plague with them. D:<!!!
number four - warmer waters and more hurricanes- as temperature rises in the ocean, the probablility of hurricans becomre more frequent and stronger. - katrina 2005
number three - droughts and heat waves increase probablility - some areas will get more wet and others will get very dry.
number two- economic consequences - diseases cost money to treat and control and conflicts exacerbrate all of these.
number one- polar ice caps melting - if the glaciers melt today, the water level of the earth would rise 230 ft. iowa is 1,670ft. above sea level. :D san fran. would be flooded very badly. o- o;
what are the main causes of global warming??? - greenhouse effect and many other small things (car exhuast,,,) global warming is the increase in the average temperature of earth's near-surface air and oceans. it would be impossible for us to live without the greenhouse effect, it would be eighty degrees cooler without the greenhouse effect. global warming is hitting four places really hard, and they are bihar india... north pole.... south australia... the maldives...
the kyoto protocol and how the US is invovled.
the united nations signed a thing about restricting the emissions of six greenhouse gases.
what needs to happen to stop global warming on all levels??? replace incandescent light bubls with compact fluorescent light bulb (cfls) install a programmable thermostat. clean or replace filters on your furnace and air conditioner.
