S ean Llewellyn I like to listen to music, watch sports, and play golf.

I see a lot of science on TV in the news or online. It's mainly environmental issues that the news likes to cover. The reason they cover this kind of science is because it affects society. They need to let the world know what is going on in the world science wise and if anything could possibly put our lives in danger. The goal behind this science message is to let the public know what could be harmful to them, if anything, or if there's anything they can do to cure or prevent it.

Day 2

Renewable energy is the energy which is generated from natural sources that can be generated again. Non-Renewable energy is the energy that is taken from the sources that are available on the earth that are limited. =====

The three types of fossil fuels are coal, petroleum, and natural gas. Petroleum and natural gas are formed by organisms that were buried under rivers and oceans. Coal was formed from the remains of vegetation that grew as long as millions of years ago.

Two examples of renewable energy are wind and solar energy. A benefit of wind is that it will never run out. The problem with solar energy is that it is not easy to come by because it costs so much. The installation of solar panels are too expensive for the energy to be used everywhere. =====

Day 3

Greenhouse Effect: This shows the process of the greenhouse effect Air Pollution: This picture shows how there is pollution everyday that we don't really know about.

Global Warming: This picture shows the overall effect of previous terms such as air pollution and the greenhouse effect. Climate & Climate Change: Weather patterns over time

Humans are contributing to global warming by driving cars and working in factories that burn fossil fuels such as coal to create energy. The greenhouse effect begins with the sun. The earth absorbs some of the energy the sun gives off but not all of it. The remaining energy shoots back into space but some gets bounced back to earth causing the greenhouse effect. The biggest factor in all this is how humans are burning too many fossil fuels. Big concerns for the future are a rise in temperature and natural disasters in certain areas.

We should care about because it will affect everyone drastically. We could die for all we know. The temperature is rising. The pollution is hurting the atmosphere and that can be prevented. We need to stop burning these fossil fuels. I think that cars are a big factor too due to what they give off into the atmosphere and they are used constantly everywhere throughout the world.

Day 4

1. Carbon fits into the picture of the greenhouse effect and global warming for many reasons. Carbon is all around us it's in the trees, air, and soil. Once humans start to interact with the environment, there is an overload of carbon and the cycle can't keep up with it. This causes the greenhouse effect and global warming.

A carbon sink is anything that absorbs more carbon that it releases.

A carbon source is anything that releases more carbon than is absorb.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Humans are negatively impacting the carbon cycle by burning fossil fuels. It releases carbon that goes into the ground for millions of years.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">The carbon cycle is also negatively affected by deforestation. I <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%; line-height: 1.5;">t releases huge amounts of carbon into the atmosphere contributing to the greenhouse effect.



Humans impact the carbon cycle positively by breathing in oxygen and exhaling carbon dioxide. Planting more trees to consume CO2 and produce oxygen is a way humans can help the environment.



Day 5

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">The carbon footprint is <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%; line-height: 1.5;">the total sets of greenhouse gas emissions caused by an organization, event, product or person.





I couldn't figure out how to copy and paste my results.

Food 44% Services 34% Shelter 4% Mobility 8% Goods 10%

I use too much electricity and drive too much. These aren't good before they can be changed. I could focus on saving the energy in my house and money. Also I could maybe carpool more to save gas.

<span style="background-color: #ffffff; font-family: Arial,Helvetica,sans-serif;">HOW CAN YOU MAKE A DIFFERENCE?

<span style="background-color: #ffffff; font-family: Arial,Helvetica,sans-serif;">Even though I'm only one person I can influence others to make the same decisions. They can do the same. It would be like a chain reaction where they see how one person tries to help the world and they follow. Everyone can make a difference. Every little bit counts because for every little thing that someone does that's bad, that person will pretty much take it back by doing something good.
