Plastic bags - in particular, the flimsy grocery store variety - have become the target of a wave of anti-bag fervor as more and more people become aware of plastic bags as an unsightly blight, a pollutant, and a threat to ocean sealife. In several California cities, the bags have been banned from use and now there is legislation moving forward that would eliminate the plastic grocery bags statewide.
First introduced in February by Assemblywoman Julia Brownley, AB 1998 passed the Assembly and is headed for the Senate Environmental Quality Committee for review before moving to the Senate for a vote. Governor Arnold Schwarzenegger has expressed interest in signing it. The bill currently provides for the elimination of the single-use plastic shopping bag and a 5-cent charge to the shopper for each paper bag used (a concession to the grocers as paper bags cost more than the plastic variety).
The single-use plastic shopping bag has become the dark iconic symbol of our growing plastic pollution problem. It is a very visible component of the ocean's plastic pollution problem, exemplified by the Great Pacific Garbage Patch, but it must take its place in the ocean with a long list of other plastic items that break down into micro-particles that leach chemicals into the water and disrupt the fundamental food chain when ingested by embryonic sealife all the way to adult animals. Many plastics are supposedly "biodegradable" but do so only in the right set of conditions - circumstances that often don't exist in reality. So, to "ban the bag" is a step in the right direction, but only a step.
Without the single-use shopping bag, we still must be mindful of these:
- Eliminate or recycle as much plastic as possible. Or turn it over to recycling centers so that it doesn't end up in landfills where little if any biodegrading takes place.
- Use paper bags instead of plastic. I've been saying "Paper, please," in my local supermarket for years. But be sure to recycle or dispose of properly - remember, landfills have been dug up only to find 50-year old newsprint intact and readable.
- Use reusable shopping bags, typically made of canvas or burlap. But be sure to occasionally disinfect them as they can have trace moisture from meat products that can produce bacteria which can be later transferred to other perishables like fruits and vegetables.

While oil pollution is, understandably, capturing a lot of our attention of late, there are other forms of ocean pollution that need our continued attention. Plastics, in its multitude of forms, constitutes a major ongoing threat not only to marine animals but the entire marine ecosystem.
Much has been written about the North Pacific Gyre, a congregation of floating plastics coming together due to the various movements of Pacific Ocean currents. While it contains pieces of plastics that pose immediate threats to fish, marine mammals, and birds due to entanglement or ingestion, there is the additional problem of what becomes of the plastics over time. Sunlight combined with water/wave action breaks the plastic down into smaller and smaller particles which can be ingested by smaller and smaller creatures - down to the plaktonic level - which means that the plastic can permeate its way through the entire oceanic web of life.
Plastics seemingly last forever. Their so-called biodegradability involves breaking down into base components, which means the separation of the various chemicals used in the production of plastics - chemicals which can prove to be toxic and, again, enter the food chain at base levels, impacting plankton, and more. So first you have large plastics pieces - discarded bags, bottles, soda can container rings, rope, netting, etc. - that can ensare, entangle, or if ingested, block the digestive tracts of a variety of sea creatures. Then as the plastic breaks down, there are the micro-particles that can be consumed by smaller creatures. And finally, there are all the chemicals being given off: low-level poisons that can have a cumulative effect.
Plastics: the "gift" that keeps on giving.
To address the issue requires industrial science to generate improved or alternative products - a new generation of plastics or plastic-like products that break down safely, as opposed to the current specific and unrealistic set of precise circumstances (light, temperature, moisture) needed for "successful" biodegradation. And there must be a more responsible use of plastics on the part of the consumer to reuse and/or recycle.
And there is also the need for legislation to nudge both industry and the consumer in the right direction. The Sea Turtle Restoration Project recently alerted its California members of 
upcoming state legislation to restrict the use of plastic bags, bottle caps, and more (plastics endanger leatherback turtles that feed on the plastic or became entangled). Within California, several cities have already banned the use of plastic shopping bags or instituted stiffer fines for plastic littering. Here are the three bills:
AB 2138 (Chesbro) - Plastic Ocean Pollution Reduction, Recycling and Composting Act
AB 2138 would prohibit food providers from distributing single-use food packaging and bags unless they are accepted for either recycling or composting in at least 75% of households in a jurisdiction and are recovered at rate of at least 25%. This policy will make the fast food sector financially responsible to:
- Switch to packaging that is compatible with the recycling and/or composting services available in the communities they serve.
- Work with local governments and recyclers to increase processing and market capacity for recyclable and compostable packaging alternatives.
- Work with consumers to ensure that their packaging is recycled or composted.
- Single-use food packaging litter kills endangered sea turtles that become entangled or mistake it for food. Single-use packaging is a primary source of urban litter and oceanic litter pollution, according to storm drain and beach cleanup studies. Polystyrene, plastic bags and other non-recyclable packaging have a high propensity to be littered because they are light and aerodynamic and are consumed away from home. Up to 80% of ocean pollution is litter from urban runoff, and non-recyclable single-use food packaging is a primary component of urban litter.
AB 1998 (Brownley) - Carryout Bags
AB 1998 will reduce dangerous plastic bag litter pollution by banning plastic bags at large retail outlets. Plastic bags are a primary component of urban litter pollution. And urban litter pollution is the primary component of marine litter pollution. Plastic already outweighs plankton in the North Pacific Gyre. Plastic pollution costs California families hundreds of dollars annually in hidden litter clean-up costs. Current retailer practices result in the distribution of approximately 19 billion plastic carryout bags annually.
AB 925 (Saldaña) - Plastic Bottle Caps
Requires plastic bottle caps be attached to the plastic container and be recyclable. As more than half of all single use beverages in plastic containers being consumed outside of the home, these plastic bottle caps can easily become part of the litter and waste stream. Beach clean-up studies find that plastic bottle caps are among most littered items. AB 925 proposes to address this problem by requiring that the bottle caps remain connected to the bottle, more than 60% of which are currently recycled, thereby significantly reducing the waste, litter and threat to wildlife posed by discarded bottle caps.
Californians can and should voice their support for these bills (they can click on each assembly bill listed above to send an email). And for you non-Californians, check your own state's government web site to see if similar legislation is in the works to protect the quality of life where you live. It doesn't matter whether your state has an ocean coastline or is landlocked, we all have bodies of water - be they freshwater or saltwater - that can be adversely effected by the growing volume of plastics we have produced over decades.
I suspect that plastics, in one form or another, are here to stay. If that be the case, then it behooves us to produce, use, and recycle plastics more responsibly. Or it will bury us.

Lead poisoning is being shown to have an effect on wildlife from California condors to bald eagles to grizzly bears and even whole environments like wetland preserves. The source of the poisoning comes from lead bullets either lodged in an animal who survived the wound, consumed by a predator or scavenger feasting on a bullet-wounded animal, or as ammunition that missed its target and contaminates the soil or surrounding ecology.
The Center for Biological Diversity reports that three endangered condors died of lead poisoning, suspected of having foraged in Utah before reaching and dying in northern Arizona. 
Four bald eagles died this winter of lead poisoning in Alberta, Canada; one of the eagles having as much as 9 times the fatal level of lead. And in Yellowstone, a recent study showed grizzly bears had elevated lead levels during hunting season, due to feeding on wounded elk. And loose lead shot has been shown to contaminate soil and even work its way down into protected wetlands
While lead-free ammunition is required in some select areas in some states, it is not nationwide for all environments. And while a total ban on all sport hunting is probably not realistic, there is some movement to extend the range of non-lead regulations. Earlier this week, California Assemblymember Pedro Nava introduced legislation to outlaw toxic lead shot from all of California's 627,000 acres of designated state wildlife areas. That's a step forward.
"We need to get lead out of wildlife areas," said Nava. "It makes no sense to allow people to leave poisonous material in our state parks."
The Center for Biological Diversity is conducting a "Get the Lead Out" U.S. campaign. Click here to learn more.
