Mt Kisco Protest: Stop the Billionaires - Save our Democracy

Every Saturday, 12:30pm - 2:00pm
Town Hall, 104 Main Street, Mt Kisco, NY 10549

Mt Kisco Saturday protest for democracy

We are asking people to line the sidewalks in front of the town hall in Mt Kisco for a peaceful protest. Bring a sign (a folding chair if you want). Bring the kids.

Our nation is under attack from within. The time to yell at the news or tune out the world is over. We need to stand up now, or soon, we won’t be able to. 

We are letting the public know our opposition to this theft of our democracy and the rampant corruption that entails. We can also show our strong opposition to abandoning global friends and surrendering to our enemies.

We were at Tesla starting February 2025, and we were successful in getting Elon out of Washington but our fight is far from over. Please join us.

A note about parking – please do not park in the Firehouse lot, the VFW lot or the church lot.   There is a large municipal lot available to park in – please park there or on the street.

*A core principle behind all Indivisible events is a commitment to nonviolent action. We expect all participants to seek to de-escalate any potential confrontation with those who disagree with our values.*

Holding Congressman Lawler Accountable

Every Saturday, Noon - 1pm
Route 59 & North Middletown Road in Nanuet

We get a great turnout on Saturdays.  We do this to protest Lawler and his support for the Trump agenda.

We Are Rockland County banner

This is a visibility campaign to make Rockland residents aware of Lawler’s ties to Musk and his duplicity parading as a moderate but voting with MAGA. Please bring friends, signs and American flags. Dress warmly and consider bringing hand and feet warmers. Hope to see you there!

Defend the Constitution in Cold Spring

Every Saturday, 10:30am - 11:30am
Route 9D & Main St, Cold Spring, NY 10516

We hold a firm belief that our elected officials must honor their oath to the Constitution above all else.  Patriots are trying to save what the Founders built so we have the option to disagree civilly again in the future. 

We are legally allowed to stand on the sidewalk and the strip of land between the sidewalk and the road.  We are not allowed to use any amplification devices (such as a bullhorn) and can not carry anything with a stick attached to it.  We also must clear the sidewalk for any pedestrians to use it. We've made the local police aware of the ongoing weekly gatherings and they are committed to protecting everyone's First Amendment rights.

Please join us. All are welcome.


  • New mini-documentary from the Sierra Club Atlantic Chapter shows how upstate NY towns are taking the lead in fighting the spread of toxic sewage sludge on farmland in NYS

    • Dangerous PFAS “forever chemicals” are found in sewage sludge, the solids left over from wastewater treatment plants, yet the NYS Department of Environmental Conservation allows big companies to dump them on farmland and golf courses in the state, billing it as fertilizer. Working with the Sierra Club Atlantic Chapter's Farm & Food Committee, Documentarian Alexa Tumbarello interviewed neighbors in the towns of Thurston and Cameron, NY (Steuben County), as well as impacted community members in Albany county. These community members took on the big companies like Casella Organics - who spread toxic sewage sludge on nearby farmland - and these community members are continuing to fight for the health of streams and fresh groundwater -- and themselves -- even as some neighbors’ wells are shown to be contaminated.  

Rep. Lawler, U.S. Energy Secretary call for re-opening Indian Point

On March 6, 2026 NY CD-17 Rep. Lawler and U.S. Energy Secretary Chris Wright held a news conference at Indian Point. They advocated for its rebuilding and reopening.

Click here to see a press release from Rep. Lawler's office.

National Experts, Env Groups, Communities Near Indian Point Strongly Oppose Trump Energy Secretary Wright’s Call to Reopen.
Entergy Closed Indian Point Due to Reduced Revenues, Increased Costs & Cheaper Alternatives.
Indian Point is a State Superfund Site with a Decades-Long Cleanup.

National experts and environmental groups joined with community groups living near the Indian Point closed nuclear reactors to vehemently oppose Trump Administration Energy Secretary Wright’s recent call to reopen the shuttered Indian Point reactor. The groups reminded the Secretary that the reactor closed because it was an economic failure, noting that the economic climate for nuclear power has only worsened as renewable energy has proven to be affordable, dependable and safe.

Mothers Out Front: A Dangerous Time for New York's Environment

Mothers Out Front with other groups and elected officials held a press conference in Tarrytown on March 13, 2026 to call on Governor Hochul to protect our environmental laws.

This is a very dangerous time for New York’s environment. 

The Trump administration has severely undermined foundational laws that protect clean air and water and has stopped our efforts to fight climate change by blocking clean energy projects and deregulating carbon emissions. 

Instead of standing strong, Governor Hochul has aligned herself with Trump’s policies:

  • She has approved once dead fracked gas pipelines New Yorkers do not need and cannot afford.
  • She is issuing permits to dirty cryptocurrency mines once deemed in violation of our Climate Law.
  • She is suspending other laws that would advance emissions free buildings./li>
  • She is proposing to gut the State Environmental Review Act (SEQRA) by exempting most housing and other development projects from necessary environmental review.
  • When you look at her budget it is clear that these giveaways to big polluters are just the start. She is proposing costly, inefficient nuclear reactors that would derail our climate goals for renewable energy.

Gov. Hochul is gung-ho on nuclear power, but we say No!

 

Backwards Thinking Hochul

Gov. Hochul is gung-ho on nuclear power, but we say No!

Nuclear Power will leave New Yorkers tied to oil and gas while the most costly energy on earth gets built, then tied to nuclear power for another 40 years!

There are dangers associated with nuclear power; emergency shutdowns, the possibility of accidents and meltdowns, health impacts and the fact that there is no repository for the deadly high-level radioactive waste.

Governor Hochul was told by NYSERDA and NYPA that the cost of building nuclear power is astronomical and will be a liability for NY State. She is ignoring and hiding the recommendation in the reports, and recklessly putting money into nuclear power. She wants to build 6 nuclear power plants and the Public Service Commission has approved an up to $33 billion subsidy (bailout) to prop up the 4 aging up-state nuclear power plants - three in Oswego County and one in Wayne County, starting in 2029 through 2049 - mid-century!

Nuclear power is not zero emissions, is not affordable and leaves a legacy of radioactive waste in communities where reactors reside.

Hochul’s financial give-away to the nuclear industry is gambling with New Yorkers' money. Hey Governor Hochul, it seems as if you may have a gambling problem. For help, call Gamblers Anonymous National Hotline at 1-855-222-5542. Renewable energy projects and programs continue to get the short end of the stick. Any money spent on nuclear power is money NOT spent on renewable energy. We all want affordable, safe, renewable energy.

Tell the Governor NO Nuclear in New York State. Please join with us in our Fax the Facts Campaign. Let’s all educate the Governor!

NY Gov. Hochul Signed Legislation to Repeal the 100 Foot Rule!

Croton press conf

Click HERE to see more photos!

The environmental community is celebrating Governor Hochul's signing S.8417/A.8888 on December 19, 2025, to remove the outdated “100 foot rule”. Passed by the NYS Legislature earlier in 2025, this bill repeals a policy that allows for-profit gas corporations to charge existing customers millions of dollars each year to pay for expanding methane gas pipelines to new customers.

It is estimated that New Yorkers paid $200 million in 2024 to hook up new residences to gas systems when there were price competitive, zero emissions, renewable heating and cooling alternatives available.  Gas utilities can charge customers directly for the construction and maintenance of pipelines, which can cost up to $6 million per mile.  Signing this bill into law will end the subsidy and put greener, more affordable electric alternatives on even footing, when it takes effect in one year.

The governor also signed several more important bills supported by Sierra Club: a ban on PFAS and other toxic chemicals in menstrual products: S.1548 (Fernandez)/A.1502 (Rosenthal); a bill that allows New York City to recycle electric batteries from electric scooters or bicycles: S.73-A (Kavanagh)/A.4641-A (Glick); and a ban on horseshoe crab harvesting for commercial and biomedical purposes: S.4289 (Hoylman-Sigal)/A.4997 (Glick).

To Protect Migratory Birds, Cuomo/Tappan Zee Bridge Lights will Dim

Cuomo/TZ bridge light dimming

Rockland Audubon Society and the Sierra Club Atlantic Chapter today announced that the Governor Mario M. Cuomo Bridge aesthetic lights are being dimmed during the spring and fall bird migration seasons in partnership with the New York State Thruway Authority.

Each fall and spring, millions of birds migrate at night, navigating by the moon and stars. Bright artificial lights can disorient them...

Remembering Fukushima and American Amnesia

NOAA map of Fukushima 2011 radiation plume

According to The Mayo Clinic staff two main features of amnesia are: 

  • Trouble learning new information.
  • Trouble remembering past events and previously familiar information.

That seems to be the case with Fukushima.

On March 11, 2011, the most powerful earthquake ever recorded in Japan struck off the country's eastern coast followed by an unprecedented tsunami. Reactors at the Fukushima Daiichi nuclear power plant site sustained major damage. Two days later the disaster caused three of the plant's six reactors to suffer a hydrogen build up which led to three subsequent explosions and released vast amounts of radioactivity. This caused radiation levels to rise in the ocean, land and atmosphere and to eventually reach the western coast of the United States.
