How Ocean Pollution Affects Humans

By Andrew Dilevics

The environment pays a heavy price for our "fast fashion" habits. The textile industry regularly contaminates waterways with dyes and waste, and washing our synthetic clothing releases plastic microfibers into the ocean. Growing enough cotton to produce just one t-shirt requires up to 700 gallon of water! Read our guest blog below to understand better just how devastating ocean pollution can be.

The ocean plays an essential role for life on earth. It provides over 70 percent of the oxygen we breathe and over 97 percent of the world's water supply. Everyday, the ocean is under attack from natural sources and manmade pollution. Pollution does not only affect marine life and their environment, it also affects mankind.

Every day, toxic chemicals are entering our oceans. These toxic chemicals have either been dumped on purpose from industrial sources or naturally flow off land and directly into our rivers and streams, which eventually end up in our oceans.

Chemicals such as oil, mercury, lead, pesticides, and other heavy metals can all be found within the ocean and can contaminate water supplies and our food chain by affecting the marine life involved. If humans are exposed to these toxic chemicals for long periods of time, then this can result in dangerous health problems, which include hormonal issues, reproductive issues, and damage to our nervous systems and kidneys.

The Hidden Costs of Fast Fashion: How Our Clothing Choices Contribute to Ocean Pollution

In recent decades, the fashion industry has evolved to offer trendy, inexpensive clothing at an unprecedented rate. While "fast fashion" allows consumers to keep up with the latest trends at a low cost, the environment pays a steep price. The textile industry, a key player in fast fashion, has become one of the leading contributors to global pollution, with particularly severe effects on the world's oceans. From toxic wastewater discharge to microplastic pollution, our wardrobe choices have far-reaching consequences for marine ecosystems and human health.

The Textile Industry's Impact on Waterways

The textile production process involves a variety of harmful chemicals and practices that contribute to water pollution. One of the most concerning issues is the release of toxic dyes and chemical waste into rivers and streams, which ultimately flow into the ocean. The textile industry is responsible for nearly 20% of industrial water pollution worldwide, as untreated wastewater is often discharged directly into waterways. This wastewater contains harmful substances like heavy metals, solvents, and non-biodegradable dyes that pose serious risks to marine life.

Beyond dyes, the production and processing of natural fibers like cotton also strain water resources. To produce just one cotton t-shirt, up to 700 gallons of water are needed for growing and processing the raw material. In regions where water is scarce, this high demand exacerbates water stress and threatens the availability of clean water for local communities.

Microplastics: A Hidden Threat in Our Clothing

One of the most insidious forms of ocean pollution linked to fashion is the release of microplastics. Synthetic fibers, such as polyester, nylon, and acrylic, are essentially forms of plastic. When we wash synthetic clothing, tiny plastic fibers known as microfibers are shed and flow into the wastewater system. Since these fibers are too small to be filtered out by wastewater treatment plants, they end up in rivers, lakes, and ultimately, the ocean.

Once in the marine environment, microfibers contribute to the ever-growing problem of microplastic pollution. These tiny particles are easily ingested by marine life, including fish and shellfish, which can lead to physical harm and toxic exposure. As microplastics move up the food chain, they pose risks to human health as well. Consumption of seafood contaminated with microplastics has been linked to digestive issues, immune system effects, and even long-term risks like cancer.

Chemical Contaminants and Their Effects on Marine Life

The ocean is home to an array of pollutants, many of which originate from human activity on land. Toxic chemicals such as oil, mercury, lead, pesticides, and other industrial waste products find their way into marine environments through direct dumping, runoff, and atmospheric deposition. These pollutants have devastating effects on marine organisms and ecosystems. For example, heavy metals like mercury can accumulate in fish tissues, making them unsafe for consumption by both wildlife and humans. Oil spills coat the feathers of seabirds and the gills of fish, impairing their ability to move, feed, and breathe.

In coral reefs, which are some of the most biologically diverse ecosystems on the planet, chemical pollution can cause coral bleaching and death. Pesticides and herbicides from agricultural runoff disrupt the delicate balance of marine life by killing plankton, which form the base of the marine food web. With plankton populations dwindling, the entire ecosystem faces collapse, impacting everything from small fish to large marine mammals like whales and dolphins.

Health Risks Associated with Ocean Pollution

The consequences of ocean pollution extend far beyond the environment; they also affect human health. When toxic substances enter the ocean, they eventually make their way into the human food chain, especially through the consumption of seafood. Long-term exposure to pollutants such as mercury, lead, and other heavy metals can lead to serious health problems, including:

  • Hormonal Disruption: Many chemical pollutants act as endocrine disruptors, interfering with hormone function and potentially leading to reproductive issues, developmental disorders, and even certain cancers.
  • Nervous System Damage: Exposure to high levels of mercury and lead can damage the nervous system, causing cognitive deficits, motor skill impairments, and other neurological problems.
  • Kidney and Liver Issues: The body's filtration organs are particularly vulnerable to damage from toxic substances. Prolonged exposure to pollutants like heavy metals can impair the function of the kidneys and liver, leading to chronic health problems.

Solutions: How to Reduce Your Fashion Footprint

Addressing the environmental impact of fast fashion requires both individual and collective action. Here are some ways we can reduce the harm our clothing habits cause to the oceans:

  • Choose Sustainable Fabrics: Opt for natural fibers like organic cotton, hemp, or bamboo that require fewer pesticides and less water. Alternatively, consider fabrics made from recycled materials, which reduce waste.
  • Buy Less, Choose Wisely: Avoid impulse buying and invest in high-quality, durable pieces that you’ll wear for a long time. This reduces the demand for fast fashion and the associated environmental damage.
  • Wash Smarter: Use a microfiber filter for your washing machine, wash synthetic fabrics less frequently, and in cooler water to minimize microfiber shedding.
  • Support Ethical Brands: Look for brands that prioritize sustainable practices, such as using non-toxic dyes, reducing water usage, and ensuring fair labor conditions.
  • Recycle and Donate Clothing: Instead of throwing old clothes away, donate them or take them to a textile recycling center. This reduces waste and keeps clothing out of landfills and the ocean.

A Call to Action

The fast fashion industry, with its substantial environmental toll, poses a significant challenge to ocean conservation. As consumers, we have the power to drive change by making more sustainable choices and demanding greater responsibility from the brands we support. Reducing our fashion footprint is not just about adopting new shopping habits—it's about protecting the oceans, the planet, and future generations.

Understanding the true cost of our clothing choices is the first step toward a more sustainable future. By taking action, we can help preserve the ocean's ability to support life on Earth and ensure that its waters remain clean and vibrant for generations to come.
