Earth Day, observed on April 22, is a global movement focused on protecting our planet. This year, as the collective acknowledgment of environmental degradation’s profound impact, we are also presented with an opportunity to champion a cause that could significantly alter the course of our environmental future—the Global Plastics Treaty.

Origins & Significance of Earth Day

Earth Day first emerged in 1970, initiated by Senator Gaylord Nelson after witnessing the catastrophic effects of an oil spill in Santa Barbara. The first Earth Day mobilized 20 million Americans and led to the creation of significant environmental policies and the Environmental Protection Agency (EPA). Today, Earth Day engages millions of people worldwide in activities aimed at preserving our planet, underscoring the power of collective action in tackling global challenges.

Why Earth Day Matters

Earth Day is crucial for several reasons:

  • Environmental Education: It raises awareness about pressing environmental issues and promotes sustainable practices.
  • Global Solidarity: Earth Day unites people across the globe, emphasizing that environmental stewardship is a shared responsibility.
  • Action and Advocacy: The day inspires individuals and organizations to engage in activities that protect the environment, from local clean-ups to global initiatives.

Earth Day 2024: End Plastic Pollution

The theme for Earth Day 2024 is the urgent need to combat plastic pollution. Plastics, particularly single-use plastics, are a severe threat to the environment, filling our oceans, killing wildlife, and disrupting ecosystems. The focus is on reducing plastic production by 60% by 2040 and eliminating single-use plastics by 2030.

The Urgent Call for the Global Plastics Treaty

In conjunction with Earth Day’s efforts, there is a significant push for the Global Plastics Treaty, a comprehensive international agreement aimed at tackling plastic pollution globally. With over 14,905 signatures, this petition calls on the United Nations and government organizations to adopt stringent measures against plastic pollution, including:

  • Reducing fossil fuel-based plastic production by 60% by 2040.
  • Holding producers accountable for environmental and health-related damages.
  • Banning plastic waste exports and incineration.
  • Promoting innovation in alternatives to plastic.

If we do not change our current habits, we will see a rise in hormonal diseases, cancers, and cardiovascular damage linked to the production and consumption of plastics. However, this bleak future is not inevitable; we have the ability to redirect our path and avoid this looming crisis.

Fossil-Fuel Pollution and Its Dire Impact on Global Health

Let’s talk about how burning fossil fuels, like coal, oil, and gas, isn’t just bad for the planet—they are harmful to our health too, particularly through the production of petrochemicals that are foundational to many industrial and everyday products. When we talk about climate change, we’re also talking about something that directly touches our lives, through the air we breathe, the water we drink, and even the products we use every day. Drawing directly from the insights from the New England Journal of Medicine‘s review article, “Health Effects of Fossil Fuel–Derived Endocrine Disruptors” by Dr. Tracey J. Woodruff, it’s evident that the adverse health impacts of fossil-fuel pollution include harmful health implications, including cancer.

Global Impact of Pollution on Health

Did you know that pollution from chemicals is a top reason people are dying prematurely, especially in poorer countries? Most of these deaths come from places that can least afford to deal with these problems. Pollution disproportionately affects low- and middle-income countries, with over 90% of pollution-related deaths occurring in these regions. Experts think over 1.8 million people die each year because of this pollution, and that number might even be too low since we don’t know the full effects of all the chemicals due to the lack of comprehensive studies.

Growing Concern of Petrochemical-Related Illnesses

A big chunk of this problem comes from fossil fuels. When we dig them up and use them, they release a bunch of nasty chemicals. Many of these chemicals interfere with the endocrine system, acting as endocrine-disrupting chemicals (EDCs). Some of these chemicals mess with our hormones, leading to all sorts of health issues, from cancer to problems having babies. It’s a big deal because these chemicals are in so many things around us—from the plastic in toys and bottles to the makeup we might wear to pesticides on our fruits and vegetables.

Over the last seventy years or so, as we’ve used more fossil fuels and made more stuff from petrochemicals, we’ve seen more people getting sick with long-term illnesses. And it’s not just happening in one place but all over the world. This trend underscores the critical need for awareness and action to mitigate the health risks associated with petrochemical exposure.

Cancer and Petrochemical Exposure

Cancer is a big focus here. It’s heartbreaking how common it has become, and part of the blame lies with the chemicals that come from using fossil fuels. Substances like benzene, found in crude oil and gasoline, and formaldehyde, a byproduct of natural gas combustion, have been classified as carcinogens with strong links to leukemia and nasopharyngeal cancer, respectively. These and other chemicals, pervasive in our environment and daily lives, are not passive occupants. They sneak into our bodies and mess with the way our cells work, leading to diseases like cancer. You might not even know you’re being exposed to them until it’s too late.

Pervasive Problem of Plastics

Moreover, the production and widespread use of plastics, a hallmark of petrochemical derivatives, contribute to the dispersion of these harmful substances into the environment, food chains, and ultimately, our bodies. Phthalates and bisphenols, used to make plastics softer and more durable, have been under scrutiny for their estrogen-like effects, which can potentially lead to breast and other hormone-related cancers.

Taking Action Against Petrochemical Pollution

So, what can we do? For starters, we need to be mindful of our exposure to these chemicals. But that’s not enough. We need big changes, like laws and policies, to make our environment cleaner and safer for everyone. And we’ve got to think about the future and shift towards sustainable and renewable energy sources.

To wrap it up, the damage from fossil fuels to our health is huge, and it’s something we can’t ignore. It’s time for all of us to pay attention, push for change, and take steps toward a world where we’re not risking our health just by living in it. Together, we can fight for a healthier, cleaner future.

Understanding PFAS: A Look at the Awareness and Impact on U.S. Drinking Water

The presence of per- and polyfluoroalkyl substances (PFAS) in U.S. drinking water has emerged as a critical environmental and public health issue. Despite increasing media coverage and governmental attention, a significant gap exists in the general public’s understanding of PFAS. An exploratory study by Texas A&M AgriLife scientists and published in PLoS ONE, aimed to bridge this gap by assessing public awareness regarding PFAS and their potential impact on community health and drinking water.

Key Findings of the Nationwide Survey

  • Limited Public Awareness: Alarmingly, nearly half of the respondents (45.1%) were unfamiliar with PFAS. Additionally, 31.6% had heard of PFAS but lacked an understanding of what it entails.
     
  • Perception of Drinking Water Safety: A striking 97.4% did not believe their drinking water was affected by PFAS, indicating a disconnect between public perception and environmental realities.
     
  • Community Exposure as a Predictor: Awareness due to known community exposure emerged as the strongest predictor of PFAS awareness. Those aware of community exposure were more informed about PFAS sources and likely to change their product usage habits.

PFAS: An Overview

PFAS, often termed “forever chemicals” due to their persistence in the environment and in our bodies, are resistant to water, grease, and heat and found in a range of everyday products including food packaging, clothing, cosmetics, and toilet paper. PFAS have been widely used in various industrial processes and consumer products since the 1940s. Their presence in products ranging from non-stick cookware to fire extinguishing foams raises significant environmental concerns, particularly in water sources. The resistance of PFAS to degradation leads to bioaccumulation, posing serious health risks such as cancer, hormone disruption, liver damage, weakened immune systems, and reproductive harm.

Regulatory Response and Public Health Implications

The U.S. Environmental Protection Agency (EPA) has recently proposed stricter regulations to limit PFAS in drinking water, reducing the maximum contaminant levels from 70 parts per trillion (ppt) to 4 ppt. This move, coupled with significant financial settlements from major corporations for PFAS clean-up, highlights the urgency of addressing PFAS contamination. However, the public’s limited awareness and understanding hinder effective response and mitigation efforts.

The Gap in Public Perception and Knowledge

The importance of knowing about PFAS lies in the need to understand the potential health risks associated with exposure to these substances. The general public’s awareness and knowledge of PFAS have been found to be limited, with only about half of the respondents in a nationwide survey stating they were aware of PFAS as an environmental contaminant. This study underscores a critical gap in public awareness and understanding of PFAS. This lack of awareness extends to the potential contamination of their primary drinking water sources.

Community exposure was identified as the strongest predicting factor regarding the level of public knowledge and awareness of PFAS and its sources. Therefore, it is crucial to provide accurate, real-time data on PFAS exposure to empower consumers to make informed decisions and take necessary precautions. Additionally, clear labeling of PFAS products is essential to allow consumers to be aware of their exposure frequency and make adjustments in product use as desired.

The Role of Effective Communication

Government agencies, research organizations, universities, utilities, and scientific institutions must collaborate to provide clear, accessible, and actionable information about PFAS, their sources, and health implications. This effort should aim to make the information relevant and understandable to the general public, encouraging informed decision-making and behavioral changes to reduce PFAS exposure. Manufacturers should clearly label their products with the presence of PFAS. This transparency allows consumers to be aware of their exposure frequency and make adjustments in product use. Consumers may want to install point-of-use treatment devices, such as under-sink or countertop filters, in their homes to remove PFAS from drinking water. These devices often use activated carbon or reverse osmosis technology to effectively reduce PFAS levels.
