Brian Kelly :] <3 When I am not at school and at lacrosse and at the gym, I don't usually play lacrosse but I have footbal coming up next year so im doing something to keep me in shape. I am really enjoying this sport and will look into it at college. In the summer I will be working at the YMCA youth camp and will also be getting ready for the Connecticut All-Star team game against Rhode Island and the Fairfield County All-Star game against New Haven County. -Coal: Coal is made from dead animals and leaves. It takes millions of years to form. Coal is formed when the dead plants and animals have been put under a lot of pressure. Because it takes so long to form, the plants and animals were probably from the prehistoric times. If we run out of coal, it would take millions of years to form Petrolium: Petroleum is formed under the earth's surface by the decomposition of marine organisms. The remains of tiny organisms that live in the sea-and, to a lesser extent, those of land organisms that are carried down to the sea in rivers and of plants that grow on the ocean bottoms-are enmeshed with the fine sands and silts that settle to the bottom in quiet sea basins. Natural Gas: natural gas contains valuable organic elements that are important raw materials of the natural-gasoline and chemical industries. Before natural gas is used as fuel, heavy hydrocarbons such as butane, propane, and natural gasoline are extracted as liquids. The remaining gas constitutes so-called dry gas, which is piped to domestic and industrial consumers for use as fuels; dry gas, devoid of butane and propane, also occurs in nature. Composed of the lighter hydrocarbons methane and ethane, dry gas is used also in the manufacture of plastics, drugs, and dyes

 * -** Renewable and nonrenewable recources are different. Nonrenewable resource are those natural resources that cannot be replaced once they are used up. Renewable resources are those resources that can be replaced as they are used up.

 * Lesson 3** : Why should we care about global warming?

1. When we talk of climate change we are really talking of changes brought about over the industrial period the last 60 to 100 years during which time we have seen increased use of energy sources that emit harmful gases into the atmosphere, which have a warming effect and hence shifting climate patterns. All this climate change and globle warming will all affect the people of the present and the future, we need to do as much as we can to help stop it.

2. Our world is being constantly damaged. Every day different companies and citizens contaminate in different ways, not caring for the consequences that their actions might have in the future.Important entities like MTV, withSwitch, have started campaigns that invite each and every one of us to save our world. Also, important persons like Al Gore have started big projects to inform people about global warming and the consequences it might have for the world.Thanks to this, many young people have started caring for the environment, and are taking better care of our world. With little actions, such as turning off the light and taking shorter showers, we can make a difference.

6. even after there have been many different models and predictions about the future effects of global warming, scientists agree that the temperature is going to rise if nothing is done to curb emissions. The effects of this rise will be dolorous. The models have changed over the years and some have been reduced from over-exaggerated numbers, but this can be attributed to the development of better technologies. With these better technologies, it has been predicted that the earth’s temperature will rise between 2-4° F over the next hundred years. Fresh water stored in glaciers will no longer be available if the glaciers melt. Unpredictable weather will destroy agriculture all over the world. As part of a delicate ecosystem, animals will disappear from the globe forever.


 * Lesson 4**: How is the balance of carbon cycle affected?

1 . All life is based on the element carbon. Carbon is the major chemical constituent of most organic matter, from fossil fuels to the complex molecules that control genetic reproduction in organisms Yet by weight, carbon is not one of the most abundant elements within the Earth's crust. In fact, the lithosphere is only 0.032% carbon by weight. In comparison, oxygen and silicon respectively make up 45.2% and 29.4% of the Earth's surface rocks.Carbon is stored on our planet in the following major sinks as organic molecules in living and dead organisms found in the biosphere; as the gas carbon dioxide in the atmosphere; as organic matter in soils, in the lithosphere as fossil fuels and sedimentary rock deposits such as limestone, dolomite and chalk, and in the oceans as dissolved atmospheric carbon dioxide and as calcium carbonate shells in marine organisms.

2 . Renewable and nonrenewable recources are different. Nonrenewable resource are those natural resources that cannot be replaced once they are used up. Renewable resources are those resources that can be replaced as they are used up.

3. response to global warming: I looked at Jaquelyn Meldons age and looked at her answer, I noticed that she included talking about the O-Zone layer which no one really talks about so its good that she included that in hers. 4. in this case this is a very simple subject, Carbon cycle requires either trees or photosyntetic bacterias (as in the early age of our planet), to conver CO2 into oxigen, know as photosynthesis sunlight is also utilized in the process.

5. ( 1 ) A) Carbon cylce: a cycle of nuclear transformations in the interiors of the stars by means of which hydrogen is gradually converted into helium with the release of nuclear energy. B) Carbon Source: C) Carbon Sink: an environmental reservoir that absorbs and stores more carbon than it releases, thereby offsetting greenhouse gas emissions. Forests and oceans are examples of carbon sinks. D) Green House Gases: Any of the atmospheric gases that contribute to the greenhouse effect by absorbing infrared radiation produced by solar warming of the Earth's surface. E) Green House Effect: The phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface. (2) Green house gases relates to the green house affect because the gases in the Green house affect are the gases in green house gasses. (3) [] [] 6. -Deforestation can affect the balance of carbon cycle because in the cycle we trees and plants to produce oxygen foe the cycle and the more trees that get cut down the less oxygen we will get. - Buring fossil fuels can affect the carbon cycle by having olution get into the air and affect everything else thats going on so the air wont be as clean. - One process that adds carbon to the atmosphere is having clean air, and one precess that takes carbon out is polution in the atmosphere.

7. "Discussion" In Thread.

1.) What is an Ecological Footprint? - Ecological Footprint is that all resources come from the planet Earth. This footprint is also defined as, " the area of productive land and water ecosystems required to produce the resources that the population consumes and assimilate the wastes that the population produces, wherever on Earth the land and water is located." 2.) What is a Carbon Footprint? - Carbon Footprint is the amount of C02 being emitting into our earth within a one-year period. C02 is the primary gas responsible for global warming and drastic change in our climate. An American is responsible for about 19-21 tons of carbon emissions yearly. The whole United States is responsible for 25% of global green house gas emissions 'while we are only 5% of the worlds populations.

4. I ALSO TOOK THE QUIZ AND IT DOESNT SHOW UP HAHA! I DONT KNOW HOW TO PROVE TO YOU HOW I TOOK IT....?

6. **HOW CAN I MAKE A DIFFERENCE!?** I deffinatley think one person can make a difference. I think this because they can recycle and not litter to help the economy last longer each year!

If someone told me they don't think they can make a difference I Brian Kelly would laugh in their face! i would this this because I think everyone can make a difference just by doing little things, like throwing there trash away.
