Water Bottles
Cellphones!!!
A quote that is sometimes said is "Ashes to ashes, dust to dust". This is DEFINITELY not true for cellphones. Every time a cellphone is thrown out, a number of toxins are released into the environment such as arsenic, antimony, beryllium, cadmium and lead. These toxins are very bad for you and the environment. Some of these toxins can even be directly linked to many health problems and diseases such as cancer, neurological disorders, damage to the nervous system, and developmental problems.
Have you ever thrown out a cellphone before? A lot of people do, usually because they either broke it, or because they have found a better, newer cellphone that they would rather have. This is a huge problem. When people do go to get rid of their phones, they have the choice of recycling it or sending it to a landfill. In a landfill, toxic substances get in the soil, water and air.

Imagine if instead of seeing gas stations every second while looking out the window, you saw green fields filled with wind turbines, and solar panels covering every buildings roof. That could happen if the world decided to use greener energy sources, instead of our current way of using fossil fuels. There are three main types of achieving this goal of a greener planet without the use of fossil fuels. The ways are using these types of energy are solar panels, dams, and wind turbines.
Solar panels ( also known as photovoltaic cells ) make renewable energy using the sun, and is very environmentally clean. They are mostly made of cystalline silicon and gallium arsenide, which is only used in solar panels. In the best conditions possible for a solar panel ( on the equator, sunny day, and it is brand new ) if the solar panel has diameter that is about 1.5 meters it creates a 2 amp current at around 2 volts. The best thing about solar panels is that they use the suns rays, which keeps on coming and the amount can not run out, they will never run out of the fuel to make their energy.
Dams are man-made structure that are built across rivers. Even though the majority of them them are used for flood prevention and to control the river's flow, lots are used to produce hydroelectric power. The energy is created when the water passes through the dam. So the more water that goes through, the more energy is created. Dams are usually huge, and the biggest one ( located in, Tadzikistan, Asia ) is 300 meters tall! ( around 984 feet ).
Wind turbines create the wind into kinetic energy. The first machines that used wind as a way to get energy was around 200 BC in Persia! Wind Farms are where many wind turbines are kept together. They usually have 3 points, and they can reach a speed of over 320 kilometers per hour! They have the highest efficiency of any the sources here.
I think that if the world replaced coal with hydroelectric energy and gas with wind energy the word would be a better place. I don't see many reasons why the world can't change there ways, and use greener energies.

Deforestation
most forests are cut down for money or so people can provide for their families.
Normally it is farmers who cut down forests so they can expand their farm, to do this the farmer will cut down part of the forest and then burn it.
Deforestation has a very bad impact on the enviroment, it kills many scpecies. Seventy percent of the worlds land animals live in rain forests and if we keep destroying the forests they will all die. Deforestation also is a major producer of climate change. Without shade from the trees the ground dries up, trees also help in the water cycle.
Without trees they also can't absorb any of the green house gasses, or CO2, this also polluting.
A solution to all this would to manage clear cutting smartly, so the forests stay intact.

Go Green
So here are some easy things that you can do to help, and you never know if you start to help maybe the people around you will follow your example and help too!
- STOP JUNK MAIL!!! -did you know that if you were to save all the junk mail that you find in your mailbox everyday for one year you would have the equivalent of one and a half trees!! You can stop junk mail by writing to: Mail Preference Service Direct Marketing Association of Canada 1 Concord Gate, Suite 607 Don Mills, Ontario M3C 3N6
- RECHARGE YOUR BATTERIES!!!- batteries contain heavy metals such as mercury and cadmium if your batteries end up in landfills these harmful heavy metals are released into the air. Did you know that the average annual use of mercury in batteries is over what the government limits in landfills by four times! You can buy rechargeable batteries or recycle your alkaline batteries, they can reuse the mercury and cadmium.
- BEWARE OF YOUR SHOWER!!- if a four person family showered for five minutes each day over one week they would use 700 gallons of water!! This would be enough water for a person to live off of for three years!!! If that same four person family had a low-flow shower head installed they would save over 14,000 gallons of water every year!
Now you know what you can do to help!! Go green and help save our planet, its the only place that we have to live!!!

Keep the air good (:
Recycle!
We could do things like using reusable bags, and we could have compost bins! Just little things like this could help the environment!
Here are some facts about recycling!
In a life time, the average North American will throw away 600 times his or her adult weight in garbage. This means thateach adult will have a legacy of 90,000 lbs. of trash for his or her children.
You can make 20 cans out of recycled material with the same amount of energy it takes to make one new one.
Enough aluminum is thrown away to rebuild our commercial air fleet 4 times every year.
A glass bottle can take as long as 4,000 years to decompose.
9 out 0f 10 people would recycle if it were made easier.

Use Compact Fluorescent Bulbs
- Replace your old light bulb with a compact fluorescent one. If you use three compact fluorescent light bulbs in your home you will save 300 pounds of carbon dioxide and $60 per year!
Inflate Your Tires
- Having your tires all the way inflated can save you $840 per year and keep 250 lbs. of carbon dioxide out of the air! You can check your tires monthly to make sure.
Change Your Car's Air Filter
- Check your car's air filter every month. You can save $130 per year and keep 100 lbs. of CO2 from going in to the atmosphere by doing this small little thing.
Fill the Dishwasher
- If you only run your dishwasher when it's full if will save you $40 a year and 100 lbs. of CO2 emission a year.
- If you Move your thermostat down two degrees in the winter and up two degrees in the summer you can save up to $98 and 2000 lbs. of carbon dioxide a year.
Change the AC Filter
- If you clean or replace dirty air conditioner filters you'll save 350 lbs. of carbon dioxide and up to $150 per year.
Take Shorter Showers
- Cut your shower short and you can save 350 lbs. of carbon dioxide and $99 per year.
Install a Low-flow Shower Head
- Using less water in the shower means that less energy is used to heat the water, saving 350 lbs. of carbon dioxide and $150 a year .
Buy Minimally Packaged Goods
- Buying less packaging reduces garbage up to 30%. You also save 1200 lbs. of carbon dioxide and $1,000 per year.
Carpool When You Can
- Carpooling with friends saves fuel. You can also save 790 lbs. of carbon dioxide and hundreds of dollars per year.
Don't Idle In the Car
- Idling wastes money and gas, and generates pollution and global warming-causing emissions. Turn your engine off if you have to wait for more than 30 seconds. Only leave it running if your in traffic.
Drive Less
- Walk, bike, carpool, or take public transit. You'll save one pound of CO2 for every mile you don't drive.
Reduce Garbage
- Recycle paper, plastic and glass, and buy products with less packaging can save you 1,000 Ibs. of CO2 per year.
Plant a Tree
- Trees suck up CO2 and create clean air for us to breathe, so we need them to survive. A single tree will absorb one ton (that's 2000 lbs.) of CO2 in the course of its life.
Unplug Un-Used Electronics
- Even when electronic devices, like your stereo and phone charger, are turned off, they use energy, so unplug 'em and save over 1,000 lbs. of CO2 and $256 a year.
Put on a Sweater
- If you put on a sweater instead of turning up the heat you can save 1,000 lbs. of CO2 and $250 a year.
Air Dry Your Clothes
- If the weather is nice, put your laundry on the line to dry. You'll save 700 lbs. of CO2 and up to $75 a year.
Turn Off Your Computer
- Shut it off when you're not using it and save 200 lbs. of CO2. Save energy by using your sleep on your computer instead of its screensaver.
Eat Your Greens
- The average American diet is full of meat products and thus contributes an extra 1.5 tons (that's 2500+ lbs.) of greenhouse gases per year, compared with a vegetarian diet. Eating 20% less meat makes the same impact as switching to a hybrid car!
Ditch the Plastic
- 2.5 million individual plastic water bottles are thrown away every hour in the US alone! That is 2.5 million to many. A plastic bottle thrown in a landfill will still be a plastic bottle in 200 years because plastic is not biodegradable! Start using a reusable water bottle and just say no to plastic!

Mounting Concerns Over Electronic Waste | |||||||||
Electronics are being replaced every day with faster and smaller devices, and yet few are recycled after these products become obsolete. As a result, mountains of electronic waste are piling up in landfills across Canada. Of even greater concern is that most electronic equipment contains toxic substances such as lead, cadmium and mercury. These heavy metals and other substances found in electronic products can pose elevated risks to human health and the environment if they are not properly managed. | |||||||||
These products also contain valuable material such as aluminum, ferrous metals and copper that could be recycled. However, due to the shortage of electronic waste recycling facilities in Canada, very little is being recovered. In response to the growing need to safely manage obsolete electronic equipment and promote product-focused resource recovery strategies, Environment Canada, Natural Resources Canada and Industry Canada are working together with equipment brandowners, provinces, territories and other stakeholders to forge a national industry-led program to take back and properly recycle unwanted equipment. How much e-waste is there?Environment Canada commissioned two studies to estimate the amount of computer equipment, phones, televisions, stereos, and small home appliances disposed each year. The first study on Information Technology and Telecommunication Waste in Canada, released in October 2000, and the Baseline Study on End-of-Life Electrical and Electronic Equipment in Canada, released in June 2003, provide a better understanding of the magnitude of the e-waste problem in Canada. Combined, these studies reveal that disposed computer equipment, phones, audio-visual equipment and small household appliances account for more than 140 000 tonnes (or 4.5 kg per capita) of waste each year in Canada. Producers Take ResponsibilitySeveral major brandowners of electronic products have identified that they are committed to developing, financing and administering a Canada-wide program to divert e-waste from disposal by ensuring that it is properly recycled. This concept, commonly referred to as Extended Producer Responsibility (EPR), places the onus on producers to properly manage their products at the post-consumer stage. EPR has rapidly gained much popularity, both in Canada and other parts of the world, because it has a potential to stimulate producers to design longer-lasting, less hazardous, and more recyclable products. In Canada, EPR has already been applied to target a broad range of post-consumer product streams such as used oil, scrap tires, batteries, beverage containers and packaging. The Canadian electronics industry established a not-for-profit organization known as Electronic Product Stewardship Canada (EPS Canada) to lead design and implementation of a national EPR program for e-waste, and liaise with Canadian governments and other stakeholders on this issue. The organization is composed of industry representatives from two industry associations, namely Information Technology Association of Canada and Electro-Federation Canada, and 16 major multi-national corporate funding partners. EPS Canada plans to roll out the implementation of a national industry program over a five-year period, starting in 2004. Designed to encourage consumers to reuse and recycle their electronics, the program will initially target personal computers, laptops, printers and televisions. In time, the program will broaden in scope to include other types of electronic equipment. Similar to other EPR programs, industry proposes to finance its national program by imposing environmental levies on their products. It is anticipated that consumers will be charged between $2 - 7 for laptops and printers, and $20 - 25 for televisions and personal computers. To help ensure that hazardous wastes and recyclables are managed in an environmentally sound manner, Environment Canada is revising its existing Export and Import of Hazardous Waste Regulations and developing federal guidelines for managing end-of-life computer equipment. Combined, these tools will provide added measures to protect human health and the environment from hazardous waste and hazardous recyclable material streams, including electronics.
Refurbishing programs aimed at recycling electronic goods are gaining in popularity. Computers for Schools is just one of many programs that encourage reuse of older electronic products like computers. The Computer for Schools program reconditions donated equipment and distributes them free of charge to schools and libraries across Canada. Computers for Schools currently delivers over 340 refurbished computers per day. To date, it has refurbished over 426 000 computers.

E-waste and You
You can help to keep electronic products out of landfills by:
- Encouraging vendors and brand owners to subscribe to a take-back and recycling program for the electronic products they sell or make.
- Upgrading or repairing electronic products where feasible instead of replacing them with new ones.
- Donating your old equipment to a family member, friend or charitable organization.
- Checking with your municipality to learn about reuse, recycling and disposal options for electronics in your area.
