Going over test times for tomorrow ( mine is 2.35-2.45 tomorrow)

Students will understand the main political and economic systems of the world, differences between te major political parties in the US, causes and effects of global warming, causes and effects of overpopulation, globalization, and major countries of the world, recent current events (Iraq, Afghanistan, Iran, Somalia)

 

Our semester blog does not have to be long! But it needs to contain what we are going to say in our ten minute slot.

 

 

Tara and Ashtun's prezi:

Dependence on fossil fuels pollution and alernative energy sources

 

 

types of pollution - air noise water radioactive land.

causes of pollution- car exshuast and factories for air

                             heat oil spills and runoff for water

 effects - bad health, polluted water, smog

china, russia, usa, india are the four countries with the worst pollution.

 

recycling and renewable energy sources can help with pollution...

 

wind, nuclear, hydroelectric, solar, geothermal, biofuels, are types of alternative energy sources.

 

wind: leaders- texas, iowa, cali. -cheapest and cleanest source around fifty thousand wind mills in the world.

concerns- birds and bats killed, noise from blades, and expensive parts

 

nuclear - fusion, fission. largest source of electricity.

concerns: not safe, health effects, nuclear waste

 

 

hydroelectric : prevents flooding, twenty percet of the worlds electricity, least expensive, and doesn't pollute

concerns: turnbines can kill fish, harm species, destroy land around dam.

 

 

fossil fuels: oil, natural gas, oil, coal, petroleum

 

what is the dependence: these days you hear about going gren, this means that we use less fossil fuels to do things, fossi fuels are things such as oil, natural gas, etroleum, and coal. you probably hear about these things most when it comes to transportation.

 

did you know, over thirty years ago .. .about 75% of the worlds energy came from fossil fuels. currently we use 90%.

 

things to decrease usage?

you bet!!! :)

 

These are several ways:  hybrid cars, using less water, reduce re-use, recycle, tuning off things such as lights and t.v.s off when not being used.

 

are there any problems that come with using fossil fuels?:

problems with burning fossil fuels: when we burn fossil fuels, we release poisonous gases into the atmosphere. they can become very expensive.

 

fossil fuels dont replenish themselves. in other words, they will be gone someday. if that problem occured, we'd have to move to the alternative energy sources.

 

Megan and Marielle:

Species destruction- the depletion of some kinds of animals from poaching and the other illegal acts against animals, and irresponsible people not taking care of the environment around them.

 

causes: destruction of habitats, poaching, deforestation, fishing for coral reefs.

 

effects: fragmentation, species will become extinct, coral reefs - it's killing he hope for curing many diseases, because coral reefs provide meds. coral reefs provide protection for coastal cities because coral reefs slow water down before it hits the coast.

 

major solutions: marine proteced areas liek sanctuaires and management areas that are used to protect endangered species and restore the health of marine life. and zoning, which is the dividing of certain areas and putting special restrictions on that area.

 

individual solutions:

join a conservation organization, recycle and reduce energy, minimize pesticides and herbicides. put decals on windows to lower the hreat of collisions with birds and windows. slow down and be alert when driving where it's possible you might run into an animal. share your enthusiasm for wildlife.
