A record number of manatees have died this year, more than a thousand, and conservation groups warn hundreds more will die from starvation and illness, the result of Florida's toxic sewage and polluted waters.

At a memorial service today in Port St. John, participants are encouraged to wear black as they kayak or paddleboard near a Florida Power and Light plant, where an experimental feeding site will be set up to help feed the slow-moving manatees that used to graze on seagrass.

Katrina Shadix, executive director of the group Bear Warriors United, said after a massive loss of habitat, she wished officials had moved faster to approve a federal supplemental feeding program.

"The starvation deaths never stopped for the manatees," Shadix observed. "They decreased, and that's because two-thirds of the population migrated out. But for the one-third that call the Northern Indian River Lagoon home all year round, they have had no food. So, they've continued to starve, they've continued to be pulled lifeless from the river."

Federal and state officials have launched a temporary field response station in Brevard County, adding small amounts of lettuce to the water. Still, the few animals spotted this week were not seen eating the leafy greens, according to a Florida Wildlife Commission spokesperson.

The memorial service starts at noon at the Port St. John Boat Ramp.

Shadix commended the work of Florida's Fish and Wildlife officials. She pointed out they are often put in the position of having to clean up after what she calls the "failed policies" of the Florida Department of Environmental Protection (DEP).

"The algal blooms killed off the seagrass, which caused the manatees to starve," Shadix explained. "If we want to get back down to it, it's all about development and the DEP's lack of regulation of the sewage that goes into the Indian River Lagoon."

Shadix filed a 60-day letter of intent to sue the DEP over the pollution. She believes state officials began the feeding program because of the legal pressure her group is exerting, citing a possible violation of the Endangered Species Act.

Other groups, including EarthJustice and Save the Manatee Club, have announced their intent to sue the federal Environmental Protection Agency for failing to protect the threatened species.

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.

Environmental groups are pushing for changes to North Carolina's industry-permitting process, which they say does not account for the cumulative impacts of environmental pollution.

People exposed to multiple chemical and environmental stressors tend to have higher rates of heart disease, cancer, diabetes and other health problems.

Sherri White-Williamson, environmental justice policy director for the North Carolina Conservation Network, said currently, the state Department of Environmental Protection does not consider cumulative impacts when approving or denying permits for facilities often located in vulnerable communities.

"Within a five-mile range of a particular community in Sampson County, there are two facilities now that have been permitted to convert hog waste into biogas," White-Williamson observed. "There are active concentrated feeding operations, they are within very close proximity to an interstate highway."

Earlier this year North Carolina Gov. Roy Cooper issued an executive order to create an Environmental Justice Lead position at each state agency tasked with collecting feedback on pollution from residents living in underserved communities. The order also directed state agencies to use federal and state funding to clean up impacted communities.

Daisha Williams, environmental justice manager for CleanAire NC, said while fostering conversations with impacted residents is important, state officials should be working toward implementing policies to incorporate and measure cumulative impacts when deciding where to site new polluting sources.

"Communities are still suffering, and we need to have tools and solutions," Williams argued. "Not just something that is kind of there to check off a box in the permitting or remediation process."

Accruing stressors from air pollution and climate change can also affect mental health. Research in the New England Journal of Medicine shows natural disasters and climate-related displacement can increase the risk of mental health disorders, anxiety and depression.

The Infrastructure Act is providing $1.2 trillion for improvement projects across water, energy, building and transportation sectors. A new report looks at how officials can use funds to address environmental justice.

Authored by the National Wildlife Federation, the report provides a framework for front-line and fenceline communities experiencing environmental-justice issues such as frequent flooding to finance solutions through infrastructure dollars.

Tatiana Eaves, an environmental and climate justice policy specialist for the federation, said the Infrastructure Act is an opportunity for decision makers.

"We must always let community leaders speak for themselves," said Eaves, "and trust them as the experts of their own lived experience and for us to listen as many communities already know what the solutions are. They just need the resources to bring them into reality."

This November, New Yorkers will vote on a ballot measure for approval of the $4.2 billion Clean Water, Clean Air, and Green Jobs Environmental Bond Act.

The bond would leverage federal infrastructure dollars to support land conservation, environmental justice and water-quality improvement.

Shawyn Patterson-Howard is mayor of Mount Vernon, New York. For almost two decades, Mount Vernon residents have lived with raw sewage backing up into their homes, flooding streets and polluting local waterways due to old and corroded clay sewer pipes.

Patterson-Howard said the infrastructure dollars could help the Black-majority city with pipe replacement.

"Without proper maintenance and investment over the last few decades, the sewer system and the stormwater system has begun to collapse," said Patterson-Howard. "So we have to find a way to improve regionally our stormwater system, which is definitely being impacted in light of climate change."

Patterson-Howard estimates replacement will cost between $250 and $300 million.

In April, Gov. Kathy Hochul announced $150 million for this project. The report suggests federal infrastructure dollars also could support grants to help low-income homeowners repair failing septic systems.
