SACRAMENTO, Calif. – California voters soon will decide if the state's ban on plastic shopping bags will stay or blow in the wind. The 2014 ban is on hold pending the outcome of Proposition 67, a simple referendum asking voters to decide whether or not to uphold the ban.

Then there's Proposition 65, which Steven Maviglio, spokesperson with the Yes on 67 campaign said complicates things. That ballot initiative would redirect a 10-cent bag fee from retailers to what opponents say is an unclear environmental fund. Maviglio noted Proposition 65 will only go into effect if it gets fewer votes in favor than Proposition 67.

"Prop 65 is on the ballot only because the plastic industry put it there just to confuse voters," he said. "The people that want to protect the plastic bag ban want a "no" vote on 65 and a "yes" on 67. And so with 17 measures on our ballot, it's very confusing and daunting."

While Prop 65 supporters claim the measure would help protect the environment, opponents argue it's an attempt to distract voters. Top financial backers of 65 are plastics companies, who also oppose 67. If 67 loses, the ban will be lifted. Meanwhile, the industry contends plastic bags are recyclable and account for small amounts of litter. But Maviglio counters the bags are not biodegradable and one of the biggest culprits of waste in the world. According to the World Economic Forum, there will be more plastic than fish per pound in the oceans by 2050.

Joshua Hanthorn, program associate with Defenders of Wildlife in California noted that plastic debris is responsible for the deaths of nearly 100,000 marine mammals each year, as well as birds and fish. He said endangered sea turtles are particularly susceptible to the effects of plastic-bag trash.

"It gets trapped in their stomach, which prevents them from properly swallowing food," he explained. "Many bags are found in turtles and it causes their unfortunate fatality. That's the number two cause of sea turtles' death throughout the world."

Maviglio believes Californians understand the dangers of plastic shopping bags, with bans already in place in 151 communities. He said many shoppers are either bringing their own bags or not using one at all.

"What we've seen in these communities is upwards of a 90-percent reduction in overall bag use," he added. "So it's not a switch from plastic to paper; it's just a dramatic reduction in bag use totally. So the impact on consumers is very small."

He said if the ban is upheld, California would be a national leader by becoming the first state to prohibit plastic shopping bags.

An environmental group is suing the U.S. Fish and Wildlife Service to protect the Arkansas mudalia snail under the Endangered Species Act.

In Arkansas and Missouri, including along the North Fork River, mudalia are critically endangered freshwater snails.

Trisha Sharma, legal fellow at the Center for Biological Diversity, emphasized the need to save the snail from vanishing entirely. She said freshwater mollusks are the most endangered group of animals in North America, and snails are the most endangered mollusks.

"We've already lost more than 70 species of freshwater snails," Sharma pointed out. "The Endangered Species Act has a very high success rate. So if we can get it listed and protected under the ESA, it's highly likely that the species will survive and be able to continue playing its important role in the ecosystems where it's found."

Sharma noted areas where the Arkansas mudalia can be found have decreased by 90% and the main threat to the species is habitat degradation, primarily from dam construction and operation along the rivers.

Sharma emphasized mudalia is also threatened by habitat loss from grazing, logging and mining. She added climate change is also expected to threaten the species.

"Part of what can make a species more resilient to climate impacts is its ability to disperse as its habitat becomes unsuitable, and to essentially relocate to areas where it can survive," Sharma explained. "But snails have a pretty narrow set of habitat requirements and very limited dispersal capabilities."

Sharma said freshwater snails play a crucial role in managing nutrients by consuming detritus and plant matter, preventing their decay and subsequent disruption of water quality, and snails are vital for food webs, converting unusable food sources into usable ones for birds and turtles.

Today is Earth Day, and one initiative in southern Arizona is helping build public gardens providing beneficial habitat for pollinators, from Monarch butterflies to bees and bats.

Emily Bishton, founder and coordinator of the Arivaca Pollinator Pathway Project, said the human population depends on these animals and insects, as many of our foods and plant-based products require pollination. But human activity and climate change have put pollinators in jeopardy and Bishton wants to increase awareness of how crucial they are.

"The best chance you have for attracting and nurturing pollinators is with the species that they've co-evolved with," Bishton explained. "They will instinctively know that is food for them, or a place they can lay their eggs. They also are more likely to be able to put up with the way our climate is now and the way it is changing."

Bishton pointed out one focus of the project is to get Arizonans to plant more native species like milkweed, which is especially critical for Monarch butterflies. She would also like people to reconsider the use of pesticides since they do kill pests but also other beneficial insects. She suggested contacting a local county extension service or master-gardener program for alternative methods.

Madian Romero, technical assistant supervisor for the Caviglia-Arivaca Library, has been responsible for getting teenagers in the area to participate in the Arivaca Pollinator Pathway Project. They not only help build garden spaces around town but grow their knowledge behind the importance of pollinators, as well as community building.

"The teens, they've come up with ideas on how to fundraise for the projects," Romero emphasized. "Each business that agrees to have a garden, it can be free."

Romero added the project has also been a character-building exercise for the young people of Arivaca, and hopes it is an experience they will cherish.

The state Department of Natural Resources and Iowa State University are looking for volunteers to help create a new Bumble Bee Atlas.

Bees are an important part of the ecosystem, and scientists are figuring out their habitats to help them thrive.

Iowa is home to at least 14 species of bumble bees that help pollinate native wildflowers and flowering crops in farm fields and backyard gardens.

Iowa State University University Professor of Sustainable Agriculture and plant pathologist Matt O'Neal said the U.S. Fish and Wildlife Service recently listed several bee species as endangered.

"And that includes the Rusty Patch bumble bee," said O'Neal, "20% of what it used to be, and that includes parts of Iowa. There is also evidence that other bumble species are in decline and so, this survey will give us a chance to see where those bees are and how abundant they are."

With that information, O'Neal said scientists can work to protect the bees' habitats and create Iowa's Bumble Bee Atlas.

It's part of a larger project to map the bees and foster bee development nationwide. Sign up online to volunteer.

The national project is part of a collaboration with the Xerces Society for Invertebrate Conservation.

Some 900 people have volunteered for the national atlas project, and counted more than 20,000 bumble bees - which O'Neal said face several major threats.

"Pesticide exposure, parasite and pathogens," said O'Neal, "and then the last 'P,' and probably the most important, is poor forage."

The researchers will work to alleviate those threats by knowing where the bees are.

Volunteers have discovered species thought to be gone from their states, contributed to new field guides, and improved scientists' understanding of bumble bee populations across the country.
