Earth Day 2010: The 40th Anniversary

April 22, 2010

Today is the 40th Anniversary of Earth Day

Happy EARTH DAY to everyone!

If you haven’t already been actively participating in doing your part to improve life here on our planet, it’s definitely time to think about contributing to the bettering of our wonderful Planet Earth — you could actively be doing more recycling, composting, planting something “green” (such as a tree, plants or maybe a sustainable garden), changing to more energy efficient light bulbs, picking up trash in the neighborhood, or simply enjoy the benefits of being more active by getting out and enjoying nature more by hiking, cycling, jogging, etc.

Today would be an ideal day to learn more about what you can do to improve your environment and be more aware of the world around you. Here are a few resources that you can look into for more information:

  • Try visiting Earth 911 — which covers real-time events around the world plus local recycling and environmental information services, the latest “green” tips and business solutions
  • Join the Earth Day Revolution by visiting the Earth Day Network Action Center — covering core issues and actions being taken dealing with Advocacy, Climate Change, Conservation & Biodiversity, Energy, Food & Agriculture, Greener Economy, Green Schools, Recycling & Waste Reduction, Sustainable Development & Clean Water
  • Or how about viewing Rising Sea Levels — which show animations of the effects of ice melting on a large scale around the world
  • Check out NASA Earth Day Photos — As part of Earth Day, NASA released their top ten favorite photos taken by the crew from the International Space Station.
  • See how the first Earth Day came about by the founder of Earth Day, the former Senator Gaylord Nelson, in his own words at this EnviroLink

Always Remember the Five ‘R’s’…..

Reduce – Reuse – Recycle – Replenish – Restore


Plastic Bottles: Are They Safe & What Do The Numbers Mean?

Have you ever noticed or paid close attention to the plastic beverage bottles you buy in a grocery or convenience store?

Drinks such as water, fruit juice, soda, iced teas, smoothies, etc generally come in plastic bottles.

Have you ever wondered what the ‘number in the triangle’ means or stands for?

There is a number stamped in a triangle (see image below) on the bottom of just about every plastic bottle we use, which varies from one to seven. I’ve read in various sources  where claims have been made that the particular number represents the recycling process of the plastic, specifically, the amount of times that exact bottle has been recycled, but in reverse order. Well … yes and no … While it does have everything to do with recycling, the number of times an item has been recycled has absolutely nothing to do with that particular number.

That number actually represents the type of plastic which is used in the manufacturing of that particular type of bottle. For example, the number ‘5’ is made out of polypropylene (PP) while the number ‘1’ is called PET which stands for polyethlyene terephthalate.

The numbers below represent the material (type of plastic) that goes into the making of that specific bottle. This number will be useful for you when sorting through the bottles for recycling, but more importantly, the number will help you to determine which bottle is best for reusing or refilling for your own personal use.

Different types of plastics are sometimes referred to as “resins” and the numeric symbols are known as “Resin ID Codes.”

The following chart represents the ‘Resin ID Codes’ or ‘Plastic Identification Number’ (PIN) found on each plastic bottle.

___________________________________________________________________________

# 1 –> PET ….. polyethlyene terephthalate
# 2 –> HDPE …..
high-density polyethylene
# 3 –> PVC …..
polyvinyl chloride
# 4 –> LDPE …..
low-density polyethylene
# 5 –> PP …..
polypropylene
# 6 –> PS/PS-E …..
polystyrene / expanded polystyrene
# 7 –> OTHER …..
resins or multi-materials

Which plastic water bottles don’t leach chemicals?

Choose your water bottles very carefully in order to prevent chemicals in the plastic from leaching into your water.

water_bottle-300x300Plastic water bottles are very convenient for carting water around when we are on the go, as they don’t break if we drop them. However, it is worth paying attention to the type of plastic your water bottle is made of, to ensure that the chemicals in the plastic do not leach into the water. If you taste plastic, you are drinking it, so get yourself another bottle.

To be certain that you are choosing a bottle that does not leach, check the recycling symbol on your bottle. If it is a #2 HDPE (high density polyethylene), or a #4 LDPE (low density polyethylene), or a #5 PP (polypropylene), your bottle is fine.

The type of plastic bottle in which water is usually sold is usually a #1, and is only recommended for one time use.  -Do not refill it- . Better to use a reusable water bottle, and fill it with your own filtered water from home and keep these single-use bottles out of the landfill.

Unfortunately, those fabulous colourful hard plastic lexan bottles made with polycarbonate plastics and identified by the #7 recycling symbol, may leach BPA. Bisphenol A is a xenoestrogen, a known endocrine disruptor, meaning it disturbs the hormonal messaging in our bodies. Synthetic xenoestrogens are linked to breast cancer and uterine cancer in women, decreased testosterone levels in men, and are particularly devastating to babies and young children. BPA has even been linked to insulin resistance and Type 2 Diabetes. Nalgene, the company that manufactures the lexan water bottles also makes #2 HDPE bottles in the same sizes and shapes, so we have a viable alternative.

Unfortunately, most plastic baby bottles and drinking cups are made with plastics containing baby_bottles_BPABisphenol A. In 2006 Europe banned all products made for children under age 3 containing BPA, and as of Dec. 2006 the city of San Franscisco followed suit. In March 2007 a billion-dollar class action suit was commenced against Gerber, Playtex, Evenflo, Avent, and Dr. Brown’s in Los Angeles superior court for harm done to babies caused by drinking out of baby bottles and sippy cups containing BPA. So, to be certain that your baby is not exposed, use glass bottles.

Check the recycling numbers on all your plastic food containers as well, and gradually move to storing all food in glass or ceramic.

Store water in glass or brass if possible, and out of direct sunlight.

Plastic Container Example Guide

Lower Numbers

Numbers 1 and 2 are the most commonly accepted recyclable plastics. These items include bottles for water, soft drinks, salad dressing, vegetable oil, milk, juice, detergent and shampoo.

Higher Numbers

Plastics also can be numbered 3 through 7, and the higher the number, the less likely recycling centers are to take the item. Items with the number 7, for example, are made of miscellaneous plastics and include sunglasses, phones, computer cases and signs.

# 1 – PET: Polyethylene terephthalate ….. Water bottles, carbonated beverages, juices, other soft drinks and oven-ready meal trays.

# 2 – HDPE: High-density polyethylene ….. Bottles for milk, bottled soaps and cleaning liquids.

# 3 – PVC: Polyvinyl chloride ….. Food trays, cling film, mineral water and shampoo.

# 4 – LDPE: Low density polyethylene ….. Carrier bags and bin liners.

# 5 – PP: Polypropylene ….. Margarine tubs, microwaveable meal trays.

# 6 – PS: Polystyrene ….. Yogurt containers, foam trays for meat or fish, hamburger boxes, egg cartons, vending cups, plastic cutlery, protective packaging for electronic goods and toys.

# 7 – Other ….. Any other plastics that do not fall into any of the above categories. An example is melamine, which is often used in plastic plates and cups.
