How Air Pollution from Climate Change is Taking a Toll on Our Eyes—and What We Can Do About It

Climate change is often discussed in terms of rising sea levels and extreme weather, but did you know it could also be affecting your eyes? Recent research has found a striking link between air pollution—a byproduct of climate change—and eye health issues like irritation and allergies. For example, high levels of air pollution can double the likelihood of needing treatment for conditions like dry eye syndrome.

Understanding the Science

What is Particulate Matter (PM)?

Particulate matter, or PM, is a mix of tiny particles and droplets in the air that come from sources like vehicle exhaust, industrial emissions, and even wildfires. The two main types, PM10 (particles smaller than 10 micrometers) and PM2.5 (smaller than 2.5 micrometers), are small enough to be inhaled or settle on the surface of your eyes. These pollutants are closely tied to human activities that drive climate change, such as burning fossil fuels.

How Does PM Affect Eye Health?

Your eyes are directly exposed to the environment, making them especially vulnerable to pollution. Particles can irritate the surface of the eyes, causing redness, itching, dryness, and even long-term conditions like dry eye syndrome. When exposed to high levels of particulate matter, the protective tear film on the eyes can break down, leading to discomfort and inflammation.

Key Findings from Recent Research

A study conducted in the Denver Metropolitan Area found significant connections between air pollution and eye health:

Higher Pollution, More Doctor Visits: Visits for eye irritation and allergies increased as pollution levels rose. For example, five days of exposure to PM10 at 110 µg/m³ made patients over twice as likely to seek treatment compared to lower pollution levels.
PM10 vs. PM2.5: While both types of particulate matter were linked to eye issues, PM10 had a stronger impact, especially during colder temperatures.
Beyond EPA Limits: Eye health effects were observed even at pollution levels below those considered harmful by the Environmental Protection Agency.

These findings align with broader studies that link air pollution to respiratory and cardiovascular conditions, highlighting air quality as a serious health concern.

Broader Implications

Climate Change as a Health Crisis

This study underscores how climate change is not just an environmental issue—it’s a public health emergency. The pollutants contributing to global warming are also causing immediate harm to our bodies, including our eyes.

Eye Health as an Overlooked Area

While much attention is given to the respiratory and cardiovascular effects of pollution, the impact on eye health often goes unnoticed. This gap in awareness means millions of people could be suffering unnecessarily.

What Can You Do?

While collective action to hold polluters accountable is essential, here are some practical steps you can take to protect yourself and advocate for meaningful change.

Protect Yourself

Indoors: Use air purifiers to reduce indoor pollution levels.
Outdoors: Wear protective glasses and avoid outdoor activities on days with poor air quality.
Stay Informed: Check local air quality advisories and adjust your plans accordingly.

Advocate for Change

Support local and national politicians and policies that reduce emissions and improve air quality, such as stricter vehicle emissions standards and renewable energy initiatives.
Join or support organizations fighting for clean air and climate solutions.

Routine Eye Care

Schedule regular eye exams, especially if you live in areas with frequent air pollution.
Discuss symptoms like dryness or irritation with your eye doctor, as early treatment can prevent more serious issues.

Summing Up

The link between air pollution and eye health is clear: the higher the pollution, the greater the risk. But this isn’t just about statistics—it’s about our quality of life. By taking steps to protect yourself and advocating for cleaner air, you’re not just preserving your vision but contributing to a healthier, more sustainable world. Remember, protecting our planet isn’t just about saving the environment—it’s about protecting our health, including our eyes!

Defend Clean Water Act from Project 2025 Threat

Water as a Sacred Force Across Cultures

Many cultures around the world revere water as a sacred and life-giving force, recognizing its profound symbolic and spiritual significance. In Hinduism, water is regarded as the essential sustainer of life, without which most living beings, including humans, would not be able to survive. Indigenous cultures, such as the Lakota Sioux in North America, honor water as a sacred element central to life and ceremonies, often referring to it as “Mni Wiconi,” meaning “Water is Life.” In Buddhism, water symbolizes purity, clarity, and calmness, representing a path to spiritual enlightenment. Across African traditions, water is scarce and precious, reflecting the community’s resilience. This universal reverence for water underscores its critical role in sustaining life and reinforces the need for its preservation across diverse global communities.

Protecting Our Water: The Importance of the Clean Water Act

The Clean Water Act (CWA), enacted in 1972, is a landmark U.S. federal law aimed at regulating water pollution to restore and maintain the integrity of the nation’s water bodies. However, the act is under threat from initiatives like Project 2025, which proposes a conservative restructuring of the Environmental Protection Agency (EPA), prioritizing industrial and business interests over environmental protections. By undermining the Clean Water Act and reducing federal oversight, Project 2025 endangers access to clean water for vulnerable communities, particularly those near industrial zones.

The History Behind the Clean Water Act

The Clean Water Act was born out of a growing environmental crisis in the mid-20th century. Before its enactment, the Federal Water Pollution Control Act of 1948 was the first U.S. law to address water pollution, but it lacked the enforcement mechanisms to make a significant impact. During the 1960s, environmental concerns escalated, particularly following events like the 1969 fire on Ohio’s Cuyahoga River, which was so polluted it ignited when an oil slick caught fire. Public outcry, combined with the environmental movement of the time, fueled the demand for stronger water protection laws. This momentum led to the drafting of the Clean Water Act in 1972, aimed at restoring and maintaining the chemical, physical, and biological integrity of the nation’s waters.

Key Provisions of the Clean Water Act

Here are the key provisions of the Clean Water Act, designed to protect our nation’s waters from harmful pollution and ensure long-term environmental sustainability:

Permits and Regulation: Facilities that discharge pollutants into surface waters must obtain permits under the National Pollutant Discharge Elimination System (NPDES). This system helps monitor and regulate pollutants from industries, municipalities, and certain agricultural activities.
Water Quality Standards: States are required to establish water quality standards for various bodies of water, ensuring pollution levels remain below harmful thresholds. If these standards aren’t met, more stringent pollution control measures are implemented.
Protection of Wetlands and Streams: Wetlands and small streams, vital ecosystems for filtering water and providing habitat, are protected under the CWA. Recent Supreme Court decisions have clarified the types of water bodies covered, emphasizing the importance of maintaining ecological balance.
Pollution Control: The CWA encourages the development of technology to limit pollution. Facilities must adhere to technology-based standards, ensuring that water pollutants are minimized as much as possible.
Non-Point Source Pollution: In addition to direct discharges, non-point source pollution, such as agricultural runoff, is a significant contributor to water pollution. The CWA provides support for research and practices aimed at reducing this type of pollution.
Public Participation: The CWA allows citizens to take legal action against polluters and government agencies that fail to enforce the Act. This provision ensures accountability and gives the public a role in protecting water resources.

Health Implications of Unprotected Water

If water bodies are not adequately protected, water pollution can have severe health consequences for both humans and wildlife. Contaminated water may harbor harmful substances like heavy metals, pesticides, industrial chemicals, and pathogens, leading to various health issues. Exposure to polluted water can cause cancer, gastrointestinal illnesses, reproductive problems, and neurological disorders. For instance, chemicals like lead and mercury can impair brain function and development, while certain pollutants are linked to male fertility issues. Vulnerable populations, including children, pregnant women, and the elderly, are particularly at risk. Long-term exposure to polluted water can result in chronic health problems, overwhelming public health systems and endangering future generations.

Why the Clean Water Act Matters Today

The Clean Water Act has been instrumental in improving water quality across the United States. Since its implementation, many rivers, lakes, and other bodies of water have shown significant improvement. However, challenges remain, particularly with non-point source pollution and groundwater contamination, as well as the latest and most significant threat, Project 2025.

Project 2025 envisions a conservative restructuring of the EPA that places industrial and business interests over the imperative for clean water and air, potentially endangering communities and paving the way for toxins, chemicals, and oil to enter our waterways. It undermines the EPA’s capacity to safeguard diverse communities and the human right to clean water by favoring the self-interest of corporations over environmental and public health protections. This initiative threatens to reverse the progress made by the Clean Water Act, removing standards that protected all of us across the country and creating a patchwork of state standards that leaves vulnerable populations, such as low-income and Indigenous communities, at greater risk. By limiting the EPA’s authority and diminishing legal recourse for affected individuals, Project 2025 weakens the essential safeguards that protect public health and the environment.

What You Can Do: Reject Project 2025, Reject Trump & Vote Blue

Individuals play an essential role in supporting the goals of the Clean Water Act and protecting water resources. Here are a few ways you can make a difference:

Learn about the threats that pollution and toxins pose to your health and the health of your loved ones.
Support policies and legislation aimed at strengthening water protections.
Participate in local clean-up efforts to protect wetlands, rivers, and other bodies of water.

The Clean Water Act has laid the foundation for a cleaner, healthier environment, and it’s up to all of us to continue building on that legacy. By staying informed and taking action, we can help safeguard water resources for future generations.

Don’t operate out of fear, operate out of hope, because with hope everything is possible.

Understanding the Global Plastic Pollution Crisis

Overview of Plastic Pollution and the Role of the Global Plastics Treaty

Plastic pollution is one of the biggest challenges our world faces today. It affects our oceans, rivers, land, and even the air we breathe. Every year, millions of tons of plastic waste end up in the environment, creating serious problems for both people and nature. Let’s dive into the key facts about plastic pollution and the steps being taken to address it through the Global Plastics Treaty.

What is Plastic Pollution?

Plastic pollution happens when plastic waste escapes from managed systems like landfills and enters the environment. When this waste is no longer controlled, it becomes a major threat to ecosystems. Plastic pollution can be broken down into two types:

Macroplastics: These are larger pieces of plastic (greater than 5mm) like bottles, bags, and other visible plastic items.
Microplastics: Tiny plastic particles (smaller than 5mm) that often come from the breakdown of larger plastics.

How Much Plastic Waste is There?

In 2020, around 52.1 million metric tons of macroplastic waste entered the unmanaged environment. This is about 21% of all the plastic waste produced by cities and towns, also known as municipal plastic waste. Municipal plastic waste comes from homes, businesses, schools, and public spaces, according to a global emissions inventory study published in Nature (s41586-024-07758-6).

What is the Unmanaged Environment?

The “unmanaged environment” is any place where plastic waste is no longer being controlled. This includes uncollected waste, litter, and open dumping sites. Once plastic enters this environment, it can move freely and cause harm to wildlife, ecosystems, and even human health.

Why Does Open Burning Happen?

In many parts of the world, especially in developing countries, formal waste collection services are either unavailable or not sufficient. As a result, people resort to open burning of plastic waste as a way to get rid of it. Open burning is harmful because it releases dangerous chemicals into the air and contributes significantly to pollution.

Global North vs. Global South: Who’s Responsible?

When we talk about plastic pollution, the world is often divided into the Global North and the Global South:

The Global North includes wealthier, high-income countries like the United States, Western Europe, and Japan. These countries have better waste management systems and tend to have less uncollected waste.
The Global South includes developing countries in regions like Africa, Latin America, and Southeast Asia. These countries struggle with waste collection, and uncollected plastic waste is a major source of pollution.

Plastic Pollution Hotspots

Certain regions are considered plastic pollution hotspots due to their high levels of unmanaged plastic waste:

Southern Asia, Sub-Saharan Africa, and Southeast Asia have the highest levels of plastic pollution.
India is the largest global emitter, contributing nearly one-fifth of all plastic waste emissions, followed by countries like Nigeria and Indonesia.
In contrast, the Global North has lower levels of pollution because of better waste management practices, though littering is still a problem.

What is the Global Plastics Treaty?

The Global Plastics Treaty is a global agreement being negotiated under the United Nations Environment Programme (UNEP) to tackle plastic pollution. The treaty aims to reduce plastic waste, improve recycling, and promote better waste management worldwide. This treaty brings together representatives from governments, industries, scientists, and environmental groups to find solutions.

Negotiations began in 2023. The next Intergovernmental Negotiating Committee (INC) meeting for the Global Plastics Treaty is scheduled for November 25–December 1, 2024 in Busan, South Korea. This meeting is called INC-5 and is expected to finalize the text of the treaty.

Why Does This Matter?

Plastic pollution has lasting effects on the environment and human health. Once plastic waste enters the environment, it can break down into microplastics, which are even harder to clean up. Without immediate action, plastic waste will continue to harm ecosystems, wildlife, and people.

Call to Action

Plastic pollution is a global issue that needs urgent attention. While some countries have made progress in managing their plastic waste, others face major challenges. The Global Plastics Treaty offers hope for coordinated global action to reduce plastic pollution and protect our planet for future generations. Tackling uncollected waste and improving waste management systems, especially in developing countries, will be key steps toward solving this crisis.

By understanding the sources and impacts of plastic pollution, we can all play a part in making our world a cleaner, healthier place.
