Plastic Waste

[edit]

[edit] Main article: Plastic pollution

In a 2015 study, the scientists also published a chart listing the top 20 nations contributing plastic waste, which has since been widely circulated. The top five plastic polluters included China, Indonesia, the Philippines, Vietnam, and Thailand. The United States ranked twentieth, the only wealthy nation on the list.[1] “We were not attempting to re-do the 2015 study,” says Kara Lavender Law, a marine scientist at the Sea Education Association in Woods Hole, Massachusetts, and the new study’s lead author. “The whole point was to examine the United States.”[1] Analyzing, 2016 data, the team found that as much as 3 percent of all plastic waste generated in the U.S. was either littered or illegally dumped in the environment. In all, the United States contributed up to 2.24 million metric tons into the environment in 2016, and of that, more than half—1.5 million metric tons—was along coastlines, meaning it had a high probability of slipping into the oceans.[1]

Plastic pollution is wreaking havoc on both the environment and human health. Microplastics, which come from the breakdown of plastic waste, are now found in 26% of marine fish—double the amount from just a decade ago. This environmental damage extends to wildlife, with species like turtles, fish, and seabirds suffering from ingesting plastic. The cost of these ecological impacts is estimated to be between $1.86 trillion and $268.5 billion by 2040.[2]

The financial burden of plastic waste management is also massive, with global costs for collecting, sorting, recycling, and disposing of plastics expected to range from $643 billion to $1.61 trillion by 2040. On top of this, plastics pose a growing human health crisis, with illnesses linked to plastic chemicals costing the U.S. between $384 billion and $403 billion annually. This combination of environmental and health-related costs highlights the urgent need to address the plastics crisis.[2]

Landfills

[edit]

In the U.S., landfilling remains a common waste management method, with municipal, industrial, and hazardous waste landfills being the most prevalent, along with some emerging green waste landfills. While most landfills in the U.S. are regulated and engineered, illegal dumpsites still exist in certain areas. Landfilling can lead to several environmental and health issues, including contamination of groundwater from leachate, air pollution from airborne particles, odor pollution from municipal solid waste, and even marine pollution from runoff. This study explores these challenges within the U.S. context.[3]

2: Water

[edit]

Freshwater

[edit]

In a report published in the November 12, 2008 online issue of Environmental Science and Technology, researchers found that freshwater pollution by phosphorus and nitrogen costs U.S. government agencies, drinking water facilities and individual Americans at least $4.3 billion annually. Of that, they calculated that $44 million a year is spent just protecting aquatic species from nutrient pollution.[4] Currently, all through the United States, more than half of the rivers and lakes that span through the country don't meet standards required from environmental regulations. A large percentage of individuals living throughout America receive drinking water from such sources in which don't meet regulations for safe water to use.[5] Pollution from nitrogen and phosphorus in freshwater not only harms ecosystems but also costs Americans money, according to Kansas State University researchers. These pollutants, often from agricultural runoff, contribute to higher water treatment costs, increased bottled water expenses, and lower property values for lakeside homes. Additionally, recreational activities like fishing and boating can decline, hurting local economies. The researchers estimate that this pollution costs the U.S. at least $4.3 billion annually, with $44 million spent each year to protect aquatic species from nutrient pollution.[4]

Trace chemicals are common in both marine and freshwater ecosystems, but they are rarely found alone. Research on which chemicals often occur together and the best ways to identify these mixtures has been limited. In our study, we found that simple correlation analysis is more effective than principal component analysis (PCA) at identifying chemical mixtures. Unlike PCA, correlation analysis can handle unbalanced data and values below detection limits.[6]

Using this approach, we identified 10 common groups of chemicals that often appear together in U.S. freshwater systems. This method helps better understand how these chemical combinations affect aquatic environments. Our research shows that correlation analysis is a better tool for identifying co-occurring pollutants, based on data from 406 chemicals across 38 locations in the continental U.S.[6]

Furthermore, underwater pollution can lead to carcinogenic and non-carcinogenic effects to many individuals who are exposed to these pollutants[3]

Air

[edit]
Main article: Air pollution in the United States

Air pollution is caused predominantly by burning fossil fuels, cars, and much more.[7] Natural sources of air pollution include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity. These natural sources of pollution often soon disperse and thin settling near their locale. However, major natural events such as volcanic activity can convey throughout the air spreading, thinning, and settling over continents.[8] Fossil fuel burning for heating, electrical generation, and in motor vehicles are responsible for about 90% of all air pollution in the United States.[9]

The issue of greenhouse gas emissions and climate change is inherently global in nature, transcending national borders and affecting countries worldwide, including the United States. The impact of greenhouse gas emissions is not solely determined by the actions of any single nation; rather, it is the result of cumulative emissions from multiple countries. While the U.S. contributes significantly to global emissions, the connection of the global economy means that efforts to mitigate climate change must involve international cooperation. The emissions of other countries, particularly rapidly industrializing nations, also influence the overall trajectory of climate change. Therefore, the United States faces the challenge of both reducing its own emissions and addressing the broader global dynamics that contribute to the problem, making it difficult to fully control the spread of climate-related issues on a national level.[10][11]

The Solution to Pollution

[edit]

Downfall Trend

[edit]

The EPA and state agencies, like California's, collect air quality data on the main pollutants regulated by the Clean Air Act, called "criteria" pollutants. These monitors help ensure air quality standards are met and also provide important data for studying pollution trends. The information shows significant improvements in air quality over recent decades. From 1980 to 2019, levels of carbon monoxide, lead, and sulfur dioxide dropped by over 80%, and particulate matter also decreased substantially. However, ground-level ozone levels only fell by about one-third.[12] Tracking emissions from specific activities or operations is more complicated than monitoring pollution levels in the air because emissions are influenced by factors like energy use, pollution control systems, equipment maintenance, weather, and management practices. Emissions can be estimated using engineering models or by directly sampling pollutants from things like smokestacks. Despite this complexity, data shows that emissions from sectors such as industry and transportation have decreased in line with overall reductions in air pollution. For example, between 1980 and 2019, carbon monoxide emissions fell by 75%, and sulfur dioxide emissions dropped by 92%.[12]

Levels of air and water pollutants that are measured and controlled have dropped substantially in recent decades, far more than CO2 emissions. However, this improvement should be interpreted with caution for several reasons. For one, while U.S. industries create thousands of chemicals, the Safe Drinking Water Act only covers around 95 of them. Furthermore, since most pollutants are regulated because they are actively monitored, pollutants that are not regulated may not have seen the same level of reduction.[13]

The bigger deduction in air pollution compared to CO2 emissions raises questions about how the two are related. Some studies suggest that reducing CO2 emissions can also lower air pollution, like when we switch from coal to natural gas or renewable energy, which reduces both. But this isn't always the case. For example, pollution control devices like filters or exhaust cleaners may not reduce CO2 emissions and could even raise them because they need extra energy to operate. However, policies that reduce pollution might cut fossil fuel use, helping to lower both air pollution and CO2 emissions..[13]

The decrease in air pollution without a significant drop in CO2 seems to support the idea that policies aimed at reducing local pollutants don’t necessarily reduce CO2 emissions. This aligns with other studies showing that U.S. air pollution policies haven’t significantly impacted greenhouse gas emissions.[14]

Policy

[edit]
Main article: United States environmental law

The United States Environmental Protection Agency (EPA) is an agency of the federal government of the United States charged with protecting human health and with safeguarding the natural environment: air, water, and land. The EPA was proposed by President Richard Nixon and began operation on 2 December 1970, when it was passed by Congress, and signed into law by President Nixon, and has since been chiefly responsible for the environmental policy of the United States.

State-level environmental policy, especially in clean air regulation, plays a key role in enforcement, air quality monitoring, and setting pollution standards that sometimes go beyond federal requirements set by the U.S. Environmental Protection Agency (EPA). However, environmental programs at the state level vary widely. Some states implement stricter air quality standards, others have stronger enforcement mechanisms, and some are known for their technical expertise in policy.[15]

To understand these differences, analysts often develop frameworks to measure and explain variations in state environmental programs. These frameworks typically assess the overall "greenness" or effectiveness of a state's policy. However, these approaches can oversimplify the diverse goals of state programs by assuming that all states pursue a single, unified purpose.[15]

In reality, state environmental policy can be understood as having three distinct dimensions: (1) a focus on improving air quality, (2) the process of implementing and enforcing regulations, and (3) the collection and analysis of information necessary for policymaking. These dimensions are driven by different factors, and each state may prioritize them differently. Therefore, to better understand the differences in state-level environmental programs, it's important to consider each dimension separately.[15]

The Biden administration has finalized new tailpipe pollution standards that aim to slash carbon emissions from new passenger vehicles by over half by 2032. While the U.S. transition to fully electric vehicles might take longer than initially anticipated, these updated rules are still expected to reduce carbon pollution by 7.2 billion tons through 2055—just 1 percent less than the original proposal. In the end, this will be one of Biden's most impactful executive actions on climate change.[16]

The U.S. EPA has also announced nearly $330 million in Climate Pollution Reduction grants for Colorado as part of the Biden-Harris Administration's Investing in America agenda. The Denver Regional Council of Governments (DRCOG) will receive $199.7 million for a zero-emission building initiative to reduce greenhouse gas emissions in the Denver area, aiming for net-zero emissions by 2050. The Colorado Energy Office (CEO) will receive $129 million to reduce methane emissions from landfills, coal mines, and other sources, and decarbonize commercial buildings. These projects aim to reduce air pollution, advance environmental justice, and support the clean energy transition in Colorado.[17]

Land

[edit]

Land can be polluted in two main ways: through the introduction of harmful chemical substances or through physical changes that make the land less useful or sustainable for future use. Waste management is always connected to land in some form, whether it involves calculating how much land is needed for a landfill to store a town's waste over the next 25 years, finding ways to protect important farmland from being taken out of production, or cleaning up abandoned waste sites that pose environmental risks. Waste managers are responsible for handling all these challenges, ensuring that land is used responsibly and that pollution is controlled.[18]
 Examples of land pollution include:

Superfund

[edit]

As with many countries, pollution in the United States is a concern for environmental organizations, government agencies, and individuals.

Billions of pounds of toxic chemicals are released into the air, land, and waterways in the U.S. each year. In 2019, approximately 21,000 facilities reported releasing 2.16 billion pounds of these chemicals onto land, 580 million pounds into the air, and 201 million pounds into water sources. Exposure to these pollutants can lead to various health problems, from short-term symptoms like headaches and temporary nervous system effects (e.g., "metal fume fever") to serious long-term risks such as cancer and early death.[19]

Pollution from U.S. manufacturing has declined massively since 1990 (despite an increase in production). A 2018 study in the American Economic Review found that environmental regulation is the primary driver of the reduction in pollution.[20]

Pesticides

[edit]
Main article: Pesticide use in the United States

Reducing pesticide pollution is a global priority. In this study, we analyzed a dataset of 21.4 million georeferenced grid cells to understand the factors driving differences in pesticide pollution risk across countries. We found that about one-third of these differences are due to variations in agricultural systems and policies, with key factors being pesticide regulations, the share of organic farming, and crop types. We also discovered a trade-off between pesticide pollution and soil erosion in the Americas and Asia, but not in other regions.[21] The use of DDT and its consequences as a pollutant is attributed as sparking the environmental movement in the United States.
