World of Water: The First Trickle

Hi everyone, and thanks for visiting our blog!

I want to discuss a subject that is very near and dear to me, especially as I write this in the middle of 2014 in California. Yes, I'm talking about water, or as we are currently experiencing, the apparent lack thereof.

There are so many things I want to say about water in California, and so many angles to this subject, that it is hard to know where to begin. Suffice to say, this will be one of many posts I compose on water.

One important consideration is the fact that much ink has been spilled and many tongues have wagged dry discussing the state of water in the Golden State. And for good reason. California is the most populous state in the U.S. with an economy that would be in the top ten of the world if counted independently, and much of this economy depends on water. Not only the billions of dollars generated by our agriculture industry, but other key sectors like the tech of Silicon Valley.


Thus, I won't profess to be an expert on water or the first to provide insight on the subject. Perhaps one of the greatest benefits I can provide is to point readers in the direction of smarter minds as I attempt to stand on the shoulders of giants and holler loud about the current crisis we face. Read brilliant books like Cadillac Dessert by Marc Reisner, or if you're feeling a little less ambitious watch the cinematic version; heck, re-watch the Jack Nicholson classic Chinatown with a close eye on the politics of water that course throughout the plot.

There are plenty of great websites and resources to learn about the current state of water affairs, from essential information provided by the state's Department of Water Resources to the think tank The Pacific Institute to Wholly H2O.

Water is a topic that can lead to some very heated debates, particularly in California. I don't mind wading into that fray and tackling some contentious issues, but before I do, I think I'll close this initial discourse on H2O with a fairly non-controversial idea: water conservation. Particularly in the midst of a drought, one of the most effective tactics is to reduce water consumption. This approach, known also as demand reduction, can be applied to other sectors, such as energy, and is both extremely cost-effective and ecological.


Earlier this year I had the opportunity to write an article for SPUR on leading water conservation strategies being employed in the Bay Area by water agencies and public utilities, which I wanted to share. Enjoy, and let me know what you think!

-------------------------------------------------------------

Last but not least, a water tip: related to the aforementioned SPUR article, I'd like to offer a suggestion for folks to reduce their water consumption. Many cities and water districts offer water audits or surveys, in which a specially trained agent comes to a person's house or apartment and comprehensively inspects the home. They look at all water-using appliances, check for leaks, make sure everything is running optimally, and then make suggestions based on their findings, provide tips, and sometimes even hand out free devices or rebates. So if you pay a water bill, call your water provider and ask if they provide this service, which is usually free of charge!

Soft and Deadly Plastic


The Plastic Problem
If you are reading this you probably already recycle, but it is easy to become partially blinded to all the sources of plastic waste and forget that the majority of our plastic cannot actually be recycled into the same products. Recycling might lessen the impact of the waste that we create but it does not, by any means, obliterate it. To make a plastic bottle or a plastic bag, new plastic must be synthesized. In addition, recycling is inefficient and depends on the demand for lower quality plastics. That this demand is not always met, is just another reason to be conscientious of the amount of plastics we consume in the first place. Although there is much to say about plastic in general, this post is going to be about one of the most common yet problematic and confusing types of plastic – soft plastics.

Soft plastics are also known as low-density polyethylene (LDPE) classified by the Society of the Plastics Industry code #4. http://en.wikipedia.org/wiki/Low-density_polyethylene They are the plastics that can be easily scrunched into a ball or crumpled when crushed by hand and include plastic retail bags, packaging, shrink wrap, and squeezable plastic bottles.



Global plastic production has increased from 5 million tons in the 1950s to over 250 million tons in 2006. Just in the form of trash bags alone, it was estimated that there were 980,000 tons of plastic generated in 2010. The amount of plastic bags (not categorized as trash bags) was estimated to be a wopping 4 million tons! (U.S. EPA, MSW report, 2010)

Now, unfortunately, a lot of this plastic has found its way to the wrong places and is having severe and detrimental effects on the environment and wildlife. In the Southern Ocean, plastic debris increased 100 times during the early 1990s (Copello & Quintara, Mar Poll Bull, 2003). Off Japan’s coast, floating particles of plastic debris increased 10-fold in 10 years from the 1970s through 1980s, and then 10-fold again every 2-3 years in the 1990s (Ogi & Fukimot, Fisheries Bulletin, 2000). It is estimated that approximately 80% of marine plastic waste comes from land-based sources (litter, industrial discharges, and garbage management) and approximately 20% comes from ocean-based sources (commercial fishing vessels, cargo ships, and pleasure cruise ships). Individuals of at least 267 species (invertebrates, fish, turtles, seabirds, mammals) have been found dead due to entanglement by marine plastics and the carcasses of 187 species have been found whose death was attributed to ingestion of these plastics (JGB Derraik, Marine Poll Bull, 2002).


The images of fur seals brought to their death struggling to get out of a mass of plastic, and bird carcasses filled completely with assorted plastics, are probably burned into your minds as well. Plastic litter is a problem for many reasons, and if you are reading this, you probably do not need to be convinced of this fact. I recently moved from Bloomington, IN (which recycles soft plastics) to Minneapolis, MN (which does not) and every time I have to throw away a piece of plastic into the garbage, these images flash into my mind. Not that by throwing my plastic bag into a recycling bin versus a trash bin makes it so much less likely to end up in the stomach of a whale, but this is how I feel. I want to modify my behavior to limit my consumption of soft plastics and to find the best ways to dispose of the ones I cannot escape (not truly inescapable, but linked to products I am at this point unwilling to give up)

Recycling (and reducing) soft plastics
If you are like me, there is still comfort in tossing something into a recycling bin, but for plastic bags this can cause problems at the recycling center as they often get caught in the sorting machinery, causing delays, breaking equipment, and ultimately increasing the cost of recycling. The process of recycling soft plastic will vary depending on your city's recycling program, so it is important to check! Recycling soft plastics is inefficient, which is why the majority of cities don’t do it at all. If you are in one of these cities, the best you can do is:
1. Limit your contribution to the soft plastic waste
2. Save your soft plastics and bring them to your local grocery store, Target, Walmart, or other.
***You can check the closest location to you by entering your zip code at this site http://www.plasticfilmrecycling.org/s01/s01dropoff.html.

In these containers you can recycle all #4 plastics, including these items:
- Furniture and Electronic wrap
- Retail and Plastic bags labeled #2 and #4
- Zip Close Food Storage bags (clean and dry)
- Plastic cereal box liners (if it tears like paper do not include)
- Plastic shipping envelopes, including Tyvek ®, bubble wrap and air pillows (Remove labels and/or deflate)
- Case wrap (e.g., snacks, water bottles)


In terms of reducing your consumption of plastics, there are a multitude of ways that you can do this - part of it is just paying more attention. It is easy to get into habits while forgetting that there are new ways to minimize your negative impact. For example, there is a clear movement to reduce the use of plastic grocery bags. However, in the supermarkets I’m always surprised to see all the people with their canvas bags, filling their carts full of produce with each item wrapped in its own plastic bag.

Some Tips
1. For produce or items in bulk, consider using washable cloth bags or dog poop bags made of cornstarch which are easily composted (Arm & Hammer makes some).
2. Avoid extra packaging by buying non-perishable products in large sizes whenever possible (a one-pound box uses less packaging, and therefore results in less waste, than two half-pound boxes).
3. Buy larger sized household products for things you use regularly like laundry soap, shampoo, dry pet food and kitty litter.
4. Stay away from products packaged in single serving food items such as microwave dinners, soups, and beverages.
5. Buy concentrates when possible because that is a lot of weight and space that is not being packaged and shipped by the manufacturer. *Juice bought in concentrate form uses up to 36% less packaging and costs 41% less than juice in plastic jugs.
6. Pick the product with the least packaging.
7. Buy the bread in the paper bag, not the plastic one
8. Buy cereal in bulk when you can bring your own container and avoid the plastic insert

But I am just one person….
A few months ago I found myself at the post office with a cardboard box full of milk cartons that I had been saving for one year and was shipping to a TetraPak recycling facility in Nebraska. After paying the $28 for shipping and walked out, I noticed the parking lot dumpster filled with cardboard boxes. At that moment I felt, what is the point? Yesterday I picked up a plastic bag in the park, filled with empty miniature liquor bottles and soda cans. I took it to the recycling can and carefully sorted everything into the appropriate bins. When I finally lifted the lid of the garbage can to dispose of the few non-recyclables, I saw that it was filled with mostly bottles and cans. These moments are challenging, but it is important to remember that this is how the majority of change occurs, through the cumulative actions of many individuals. 

And every little bit helps. The plastic that you save could even mean a few more happy elderly seals.
