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.

How You Can Help

This Earth Day, let your actions speak louder than words:

  • Sign the Global Plastics Treaty Petition: Join the global movement to push for a binding international agreement that addresses plastic pollution head-on.
  • Reduce, Reuse, Recycle: Make personal changes to minimize your plastic usage.
  • Participate in Community Actions: Engage in local Earth Day events that focus on cleaning up and reducing plastics and help spread the word.

Final Thoughts

Celebrating Earth Day means committing to protect our planet continuously. By supporting initiatives like the Global Plastics Treaty, we can take significant steps towards a sustainable future free from plastic pollution. This Earth Day, let’s not just celebrate our planet; let’s take concrete steps to save it. Together, we can make a difference, but only if we act now. Join the movement, sign the treaty, and be part of the solution. We have the power to change our environmental destiny and ensure a healthier planet for future generations.

Our goal is not just an environment of clean air and water and scenic beauty. The objective is an environment of decency, quality and mutual respect for all other human beings and all living creatures.

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.

Hashtags:#BeatPlasticPollution and #WorldEnvironmentDay

June 5th, 2023, will mark the 50th anniversary of World Environment Day, which was established by the United Nations Environment Programme (UNEP) in 1973. This year, the event is anticipated to attract tens of millions of participants both online and through in-person activities, embodying the spirit of environmental advocacy.

Addressing plastic pollution

This year’s theme is focused on finding solutions to plastic pollution. The occasion underscores the consequences of actions and inaction taken by individuals, businesses, and governments in response to plastic pollution. It also highlights the pressing need to amplify these efforts and transition towards a circular economy. To assist in these efforts, a Beat Plastic Pollution Practical Guide is available, outlining steps to halt and reverse the detrimental effects of plastic pollution.

An urgent need

Our planet is in crisis, besieged by the overwhelming weight of plastic waste. Despite its numerous applications, plastic has become detrimental due to our dependence on single-use plastic products, which cause significant environmental and health issues.

As per the UN, globally, one million plastic bottles are bought every minute, up to five trillion plastic bags are used each year, and 400 million tonnes of plastic waste are produced annually. Approximately 36% of all plastic is used for packaging, including single-use items for food and beverage containers. Sadly, around 85% of these items end up in landfills or as unregulated waste. Less than 10% of the seven billion tonnes of plastic waste generated worldwide has been recycled. The most prevalent types of plastic waste found in the environment include cigarette butts, food wrappers, plastic bottles and caps, grocery bags, straws, and stirrers.

Environmental harm

Plastic waste can persist in the environment for centuries due to its durability and resistance to degradation. Nearly all single-use plastic products are manufactured from fossil fuels, contributing to the escalation of greenhouse gas emissions. Most plastic items merely break down into smaller microplastics, which can infiltrate the human body and accumulate in various organs. The impact of this phenomenon on human health remains largely unknown. Microplastics are now ubiquitous and are a part of the Earth’s fossil record. They have even led to the creation of a new marine microbial habitat, known as the “plastisphere.”

How you can help

Urge your local and national leaders to take decisive action by eliminating problematic plastic packaging, redesigning products for sustainability, and promoting transparency in sustainability information. Additionally, you can participate in beach or river clean-ups, shop sustainably, adopt a zero-waste lifestyle, advocate for change, choose sustainable fashion, and opt for plastic-free personal care products.
