MACKINAW CITY, Mich. -- A group of artisans from Lummi Nation is carrying a 25-foot carved totem pole from Washington state to Washington, D.C., and making its last stop in Mackinaw City on Michigan's Upper Peninsula.

The group, the House of Tears Carvers, is raising awareness about the need to protect sacred sites at risk from development and natural-resource extraction.

The Line 5 dual pipelines run under the Straits of Mackinac and have spilled more than a million gallons of oil into the surrounding waters over 50 years.

Whitney Gravelle, executive council president of the Bay Mills Indian Community, said more than half of Bay Mills citizens rely on the Straits of Mackinac for commercial and subsistence fishing.

"Our Anishinaabe teachings, our creation stories, our history here are all tied to the Straits area," Gravelle explained. "It is literally one of the centerpieces for cultural contact and interaction for thousands of years."

Bay Mills Indian Community, as a signatory of the 1836 Treaty of Washington, reserves the right to fish, hunt and gather in the Straits of Mackinac and the surrounding region. Gravelle argued treaty rights are put at risk by the Line 5 pipelines. The House of Tears Carvers is holding a blessing ceremony at Michilimackinac State Park today.

Gravelle pointed out her community has been engaged in efforts for years against the pipelines, both in legislative and policy arenas, as well as through activism.

"Our tribal citizens have been extremely active and involved in these grassroots organized movements in order to raise awareness," Gravelle recounted. "Not only about Line 5, but on the numerous effects that we're seeing from climate change, pollution or other environmental degradation across the state of Michigan."

Gravelle added the Straits of Mackinac also have great historical value. There are terrestrial and bottomland archeological sites, submerged paleo landscapes, cemeteries and isolated human burials.

She emphasized understanding the culture and history of the area helps us understand where we need to go in the future.

"That's why Bay Mills Indian community continues to do this work, why we're collaborating with other tribal nations, like the Lummi Nation," Gravelle stressed. "To bring awareness to these issues, so that we can preserve and protect everything for the next seven generations."

A coalition of community organizations teamed up in Oregon to force a chronic polluter out of business, and bring environmental justice to a nearby neighborhood.

The groups, known as the Core Team, used community engagement, education and pressure from regulatory agencies to force the J.H. Baxter Company to close.

Residents of the West Eugene neighborhood say for years, the wood-processing mill dumped cancer-causing chemicals into their air and the soil.

Lin Woodrich is co-chair of the Active Bethel Community. Woodrich helped organize neighbors to pressure the company to do soil tests, but many residents were afraid to participate.

She said company officials didn't treat them as people.

"They talked about us as data, and I kept explaining that these are people," said Woodrich. "These aren't data. These are people with homes and families and the poisoning that's going on. We need to find out, really, what is going on."

Baxter & Co. was a lumber-treatment facility that operated in West Eugene for more than 70 years. It finally closed its doors in January after pressure from state officials and numerous complaints of unbearable smells related to pesticides, creosote and petroleum products.

Woodrich said company officials tried to intimidate the homeowners in the low-income neighborhood with letters written by lawyers announcing soil tests, and the official-sounding text frightened many away from participating.

She said the groups sprung into action, going door-to-door to organize neighbors to pressure state officials to deal with Baxter.

"There's no question about it that my group going out," said Woodrich, "we had our vests on, our official volunteer vests. I had a flyer, and we made sure that they understood how important it was. I definitely think that we made a difference."

Several other groups and organizations helped the coalition through the hearings. Rebeka Dawit is an attorney with the Crag Law Center.

She said she and others provided legal guidance to the groups to help them though the bureaucratic maze and reach their goals. She said that can be a daunting process.

"The clean-up process or the accountability process doesn't just kind of go through bureaucratic administrative processes that doesn't include the public or doesn't involve information that empowers community members that are directly affected," said Dawit.

This week is a great chance to enjoy the great outdoors - with more than fifty free events, up and down the state of California, as part of Latino Conservation Week.

People can go paddle boarding, hiking, take nature walks, attend film screenings and more.

Juan Rosas is a conservation program associate with the Hispanic Access Foundation - which organizes the event with the help of dozens of community, non-profit, faith-based, and government organizations and agencies.

He said the program dispels the misconception that Latinos don't care about the outdoors.

"A lot of the Latino community do live in nature-deprived areas," said Rosas. "So, to be able to take them hiking and fishing, camping - have virtual events, webinars, educational resources that they can firsthand experience - is the goal of Latino Conservation Week."

An event on Saturday, July 23 will promote the proposed Western Riverside County National Wildlife Refuge.

Rep. Ken Calvert - R-Corona - and Rep. Mark Takano - D-Riverside - recently reintroduced a bill in Congress to officially create the new urban refuge. They say the idea is to improve access to nature for millions of people living in Southern California.

This year's event slogan is "Disfrutando y Conservando Nuestra Tierra,"which means "Enjoying and Conserving Our Land." According to Rosas, this annual event has really caught on, growing significantly over the years.

"It started in 2014 with nine events," said Rosas. "And this year, in year nine, it looks like we're just nearing 200 events that are going on, all around the United States. So, we're so excited."

Many of the events touch on environmental justice themes, since so many Latinos in California labor in manufacturing and agriculture - industries that often pollute the air and water in nearby communities.

With a historic budget for parks and recreation, New York City is crafting strategic plans to increase tree canopy through an environmental justice lens.

New York City's $624 million parks budget includes funding for capital projects such as planting 20,000 new trees. City Council recently held an oversight hearing on increasing tree canopy, which gave residents the chance to provide input on shade access in their community.

Council Member representing Elmhurst and Jackson Heights, Shekar Krishnan - who chairs the Committee on Parks and Recreation - said the hearing can inform solutions to addressing disparities of tree presence in different neighborhoods.

"In particular, low-income communities of color have far less tree-canopy coverage than other neighborhoods do," said Krishnan, "and that directly results in hotter temperatures known as the 'urban heat island' effect. And so the brunt of the lack of tree-canopy coverage isn't shared equally."

The budget also includes funding for stump removal, which can make way for new trees. A report from The Nature Conservancy found that as of 2017, the city's overall tree canopy was about 22%.

Victoria Sanders - research analyst with the New York City Environmental Justice Alliance - said as New York City moves forward with plans for improving tree-canopy equity across the city, communities that have long been disinvested due to racially discriminatory policies such as redlining must be prioritized.

"There's all this red tape that impacts the way funds can be used," said Sanders. "A lot of the trees that are being planted are replacing trees that already exist. So I think there needs to be maybe some pushback so that a larger amount of the money can be put toward making sure there's equitable tree distribution."

Emily Nobel Maxwell - New York Cities program director for The Nature Conservancy - said she's excited by the budget investments in urban forests, but said there's more work to be done.

"We know that to better ameliorate the impacts of extreme heat, we need more tree canopy," said Maxwell. "It would mean protecting and maintaining the canopy we have. And that requires maintenance funding, laws to protect our canopy, it requires enforcement."

The Forest For All NYC coalition has called for a citywide goal of 30% tree coverage by 2035.
