Plastic bags : Facts and why we need to stop using them!

Everyone knows that plastic is bad for the environment. We don’t need to spell it out again, but some facts are important to know and since people respond to numbers, here are a few facts on plastic bags I found on LivingGreen that may help solidify your resolve :

  • Less than 1% is recycled. It actually cost more to recycle a plastic bag than to produce one-there is no monetary incentive to recycle plastic bags.
  • Many of our garbage bags are dumped illegally in our oceans. A study in 1975 showed that ocean going vessels dumped 8 million pounds of plastic bags annually.
  • Billions of plastic bags also find their way into oceans via rivers, drains and sewage pipes where the effects on aquatic animals such as turtles, sea birds, whales, dolphins and seals are catastrophic. These animals ingest plastic or become entangled resulting in agonizing deaths. The unsuspecting creatures often mistake the floating plastic for food! Plastic bags are found in most oceans of the world. (World Wildlife Report, 2005)
  • A study of albatross chicks on Midway Island, near Hawaii in the Pacific Ocean, found that nine out of 10 birds had plastic garbage in their gullets.
  • Plastic bags do not decompose! They break into smaller, more toxic petro-polymers which eventually contaminate our soil, our waterways. In time the toxic microscopic particles enter our food chain. ( 2007)
  • Plastic cannot be burned or buried safely. When it is burned it produces fluorocarbons which are carcinogens.
  • When we bury plastic bags they block the natural supply of air and water to the soil. This affects plant life directly and the chain of life indirectly.
  • Plastic bags can even cause landslides when plant life in mountains is reduced. Plastic bags clog the sewage pipes and often cause water to be stagnant. It reduces the water retaining capacity of the soil and this in turn affects the water table.
We all (I hope) try our best at reducing the amount of plastic that is used and thrown away. This is not only for our environment and wildlife, but for our health as well. Recently, new technologies in plastic bag production have led us to believe that maybe some weren’t as bad, but are they?

Traditional bags are made from petroleum products which can release toxic compounds into the air that are known to cause major health issues.

Now, more and more bags are made from polymers called polyethylene that are, for most part, recyclable. Great right? Not exactly. The problem seems to be that bags can be made of different types of resin that although look very similar, when broken down, can’t exactly be easily recycled. So if you ARE going to put plastic bags in the recycling, make sure that they have the recycling symbol with the numbers 1, 4 or 5, as other numbers may not be recyclable in your area.

What about the new trends of biodegradable bags? This seemed to be the greatest idea since the corn and potato starches are made to biodegrade or photo degrade when in contact with air or light in less than 18 months! WONDERFUL! Not… this will only work if you bag is on top of a free standing hill of trash and according to an amazing article on, 95% of all trash is land filled. “In landfills, garbage is buried beneath layers of soil that make it difficult for air or sunlight to reach discarded items. The fact is that most plastic bags just don't degrade, even in a compost pile. There are some new starch-based plastics that may be more degradable. But few grocery bags are made from that type of product.”

So, short of it is there really is no easy answer to plastic bags besides stopping using them. Carry around reusable bags in your car, buy little foldable bags to put in your purse or pockets, carry out small items when you know you don’t need to carry it very far and if you MUST, ask for paper bags when leaving the store! Those are easily recycled, are often made of recycled paper and can easily be transformed.

As a final note, here is the link to Thomas’s post, on Renewables at Home, that responded to my challenge and wrote an excellent article you all should read! Thank you for jumping in Thomas!


Here is another one of my readers (Harri Pao) that took the challenge and wrote about how they eliminate plastic bags in their daily lives.

A wonderful article, Yanic! You bring up a good point about the Eco-friendly bags made out of corn, soy, etc. They work great, as you said, if they are lying on top of the heap or in an aerobic environment. Unfortunately, landfills are anaerobic environments ... meaning that there is no air (which is necessary for decomposition). Even fruits and vegetables in a landfill will take years and years to biodegrade (there have been reports of 50 year old bananas ... ewwww). So, the less we send to a landfill, the better.

BTW ... I'm using your suggestion for this week's challenge. :)

Have a great day!

A great point about the degradable bags and the suggestion for stopping use plastic bags. I've just written and posted it for Small Footprints's's just our daily experience to reduce plastic bags waste.As your suggestion, we've done some of them, also, as commented Small Footprints we'll try...the less we send to a landfill.

Kind regards,

Great post, Yanic, and thanks for the link and kind words :-)

I've been reading a few of the posts for the challenge, and it's refreshing to see several different takes on one subject.

Yanic said...

Small Footprints! Thank you for stopping by. Very happy you enjoyed.

I'm looking forward to seeing how people react to the next challenge. *giggles*

Harri Pao : Thank you for joining in! I've edited my original post to include your link. I hope you'll come back and check this weeks challenge!

Thomas : I'm glad you liked and you are welcome. I've been reading some of the posts as well and am very happy that people have been touvhing many different parts of the issue. said...

Generally, the awareness that plastic bags is for the environment is there. But, many are using it out of convenience.

Grampa Ken said...

A lot of the problems consumers have with recycling is the lack of readily available detailed information. This is particular with the various types of plastic. "Where do I recycle these containers, fasteners, cellophane, packing, bags etc?"

Recycling information is out there but often you may need to spend some time trying to find it and it may not be convenient. I thing a lot of municipal governments are not doing their duty.

The Earth has been facing immense pollution from our garbage and consumption. The latest deadly pollution is plastic bags that fill up the landfills. With plastic bags becoming a growing concern, cotton bag has become the new way to help stop the pollution.

With plastic bag pollution being a rising concern, many shoppers need to start using reusable cotton bags in order to stop the pollution.

Plastic bag pollution is very deadly and takes hundreds of years to break down. Even if the component is broken done, the deadly chemicals will go into the ground and water system. By reducing the usage of plastic bag, Earth can recuperate. That's why cotton bags should be used world wide to help reduce the pollution.

It is our generation to stop the pollution and start using cotton bags as the solution. With global warming going out of hand from gas exhaustion, we don't need any more problems especially plastic bags that are harmful when broken down naturally. These broken down elements cause sickness and destruction to the air, soil and water system.

Use cotton canvas bags starting today as a way to stop the plastic pollution that is becoming a major threat to the environment. Our lives are threatened ever more from the growing usage of plastic bags. It is time you bring a canvas bag to shopping the next time you go to a supermarket.

The plastic is ruining our drains and let outs...they are not ever properly disposed.They have to be stopped now and today.Bio degradable bags are being used by many companies...and should be.

Nice to read that about Facts and why we need to stop using them, good information.
