Logging On the previous page, we talked about the how trees benefit us, here, we will go deeper into it. Paper uses: money, check, books, diary, letters, packaging, construction and many other uses such as sandpaper...etc So why are these paper products important? Money- Without money, you can’t live. Of course, you could use credit card, but you never know when you could get into a huge debt. Art paper- Construction paper offers us uses for paper collage. Newspaper makes paper mache. Cute paper developed origami. Cardboard are perfect for card. Letters- An old fashioned letter is always sweet. Packaging- Upon Christmas, don’t you just love the freshly wrapper presents. Very nice. No smooth wood with sandpaper unless you are an expert at sawing and everything.

Imagine on a sunny day, you went out to

the park. Ahhh! Nice and refreshing... However, you feel very hot, so you walked under a shady tree and sat down. You took out your sketching pencils and sketch book. Looking at the beautiful blossom, you lightly and gently sketched them. Observing carefully, you see an apple tree. Delighted, you picked a plum and red apple. Suddenly, you see some children coming. The frolicsome kids started climbing trees, giggling non-stop. From the above paragraph, you could see that trees have many uses: Shade, Paper, Wood(pencil), scenery, fruits. The two major uses of trees are paper and wood. However, there are two more things that trees do: trees also help decrease global warming and provide oxygen for us. Maybe not very significant, but a little is better that nothing. How? We human breathe in oxygen and breathe out carbon, while trees breathe in carbon, and using the process of photosynthesis, they combine sunlight, carbon and water to create sugar, which is food for themselves. Then, they breathe out oxygen. However, how does this help global warming? Global warming is caused by greenhouse effect and carbon is the most prominent type of greenhouse gases on Earth. Every year humans add over 30 billion tons of carbon dioxide in the atmosphere by these processes, and it is up thirty percent since 1750 . SO the trees absorb carbon. Win=win. Also, the trees reflect green visible light, which is not as easily absorbed by infrared radiation, which also helps global warming.

Awesome Trees

Paper overusage

Humans have been depending on trees for ages. We use them for paper, tissues, cardboard boxes, wood, and most importantly, oxygen.

However we’re over-doing it. In the prehistoric age, three fifths of the earth surface is covered in forests, however now it is shrunk to 30% and gradually decreasing.

P.S.: This brochure is eco-friendly because we don’t print it which saves paper and ink. However please email it around to spread the message. P.P.S.: Don’t spend too much time reading it ‘because you’ll be wasting electricity and that uses fossil fuels and emits pollutant. Go green!


Type to enter text Paper cons: 1) It kills trees-the carbon absorber, oxygen giver, and green light giver aka reflecting green visible light. 2) There are negative impacts in the paper-making process. I will explain that later. 3) It fills up landfills. 4) Most paper aren’t reusable

The awesome solution Common FAQs: How does it work? You recycle all of your current replaceable paper products and recycle them into un-replaceable paper products. Then, you buy digital products and go digital. Simple, right. How to Ditch paper and go digital. By ditching paper, you will eliminate the need of buying paper. You could read books on digital ebooks; light, easy to read, portable, many choices, cheaper since it doesn’t requires publication. Many e-books are free as well. No more heavy textbook carrying, YAY! Write notes easily by typing, no more bumps on index finger because of writing too much. Practices hand-eye coordination skills. Looks more stylish. Good, good, good. Ditching paper also means not as much environmental impact, yay! Why should you follow it?

Bad impacts take place in 3 stages of processing paper, starting with the harvesting of trees, then the process of turning wood fiber into pulp, concluding with the throwing away of paper products. The above diagram shows how paper recycles. Not only it is eco-friendly, it reduces waste in landfill.

Since paper is one-time use, while digital is not, it saves you money. Second, it’s convenient. Emails are so much more convenient than letters. For letters, you have to buy paper and pen, spend time writing and that causes the ugly bump on your index finger. Then, you have to drive (using gasoline and emitting pollutants) to the stamp office. Then the stamp office would either use air mail which causes planes to emit Co2 or vehicles. Meanwhile, for email, all you have to do is to type and send. Easy peasy lemon squeasy. If you don’t want to hurt your eye, just don’t stare at the screen while typing and stare at it for a few seconds when clicking send.

Scientific facts that it will work: CO2 is measured per kilowatt-hour (kWh) of electricity. It all depends on the source of the electricity. If your supplier uses wind, solar, hydro, or nuclear power, then the CO2 impact is very small. If they generate using coal, natural gas, or diesel, then the output of CO2 per kWh is much higher. Here are some typical values in grams of CO2 per kWh for various generation technologies. Coal = 950 Oil = 900 Natural Gas = 600 Gas (combined cycle) = 450 Solar photovoltaic = 50 Nuclear = 6 Wind = 4.5 Hydro = 3 Now, most likely to use coal. and about an hour of computer a day. 365*1*950=346750 g= 346.75kg US population= 307,006,550 * 346.75= 106454521200kg= 117346022 ton= 0.1 billion ton Now, let’s compare it to the impact of producing paper: Bad impacts take place in 3 stages of processing paper, starting with the harvesting of trees, then the process of turning wood fiber into pulp, concluding with the throwing away of paper products. 1) When they harvest trees, paper-making industry often uses old growth and environmentally sensitive trees. That is logging. What happens after logging? All the tons of carbon get released. making the pulp and paper require large amounts of water and toxin chemicals to make the paper look whiter. The industry also releases 212 tons of harmful substances to the air per year. It is also ranked third in using industrial water. The destruction of tree adds approximately 2.2 billion carbons each year, which is equal to what US emits every year. If this is what 1 billion dollar (each is 100 dollars note) look like, imagine 1 billion carbons. P.s. these notes are made of paper which we don’t want to use.


Examples of my awesome solution already taking place Now, let’s wow you with some facts: 1) The normal office employee produces about 120150lb of recoverable white paper a year. 2) Each year, Americans dispose 4 million tons of paper —enough to build a 12-foot great wall from California to New York. 3) Paper is thrown away the most; 35% of trash we throw is paper. 4) When paper decomposes or burned in incinerator. Chemicals from ink is emit into atmosphere. 5) Deforestation is happening really fast, only 20% of old-growth trees were undamaged, and almost half face threats from logging. 6) American consumes more than 850 million trees; use more than 50 million tons of paper every year. 7) It takes about 17 trees and 390 gallons of oil to make a ton of paper. When it is disposed, it takes up 8 cubic feet of public landfill. 8) Every 1 million pieces of paper not produced saves 85 trees. 9)8.5 million acres of trees is an area bigger than Belgium and also the amount of trees needed for 1 trillion pages of paper.

Online Newspaper, IndependenceUK has quoted that “ It is time to ditch paper and pen and go digital. Students now are forced to do something they will never do in real life: write non-stop for 3 hours in a test. Nobody doesthat now Now, we use computer.” According to East Valley Tribune, “For decades,cities wasted much money printing brochures, with each one taking up lots of writing, every city council meeting. However, East Valley cities ditched paper and go green---go digital. Mesa was latest switching and Scott Somers is the first councilman to swear paper off. He said that 4 years of reign, they used up a forest their children will never see. For every 2 meeting held a month, Mesa prints about 20 brochures, a.k.a. 10,000sheets of paper every time. If they were stacked up, it would be about 3.5 feet tall.” As you can see,many have already started working to make a difference. Together, we could make a difference.

Fun fact: In 2000, people said that: “Soon, it’ll be a paperless world.” Doesn’t seem like happening now.
