The Problem with Plastic – An Ocean View

Plastic pollution in the ocean is a significant environmental issue that poses various problems and impacts ecosystems, marine life, and human health. What affect does plastic have on our oceans? Here are 6 ways plastic is detrimental to our planet’s wellbeing from an ocean’s view:

  1. Threat to Marine Life: Marine animals often mistake plastic debris for food or become entangled in it. Sea turtles, birds, fish, and marine mammals may ingest plastic particles or become trapped in discarded fishing gear, leading to injury, suffocation, internal blockages, and even death. Plastic pollution can disrupt entire marine food chains and have cascading effects on the overall ecosystem health.
  2. Ecosystem Disruption: Plastic debris can physically smother and damage coral reefs, seafloor habitats, and other marine ecosystems. It alters the natural habitat structure, reducing biodiversity and the ability of marine organisms to thrive. In some cases, invasive species can hitchhike on plastic debris, leading to the spread of non-native species and disrupting local ecosystems.
  3. Microplastic Contamination: Over time, larger plastic items in the ocean break down into smaller pieces known as microplastics, which are less than 5 millimeters in size. Microplastics are present throughout the water column, sediments, and even in marine organisms. They can be ingested by small marine organisms and make their way up the food chain, potentially reaching humans who consume seafood. The long-term impacts of microplastic exposure on human health are still being studied.
  4. Ocean Health and Water Quality: Plastic debris releases harmful chemicals and toxins into the water as it degrades, posing a threat to the health of marine organisms and the overall water quality. These chemicals can disrupt hormone systems, impair reproduction, and weaken immune systems in marine life. Additionally, plastic pollution can also negatively affect coastal tourism, fishing industries, and local economies that depend on healthy oceans.
  5. Global Environmental Impact: Plastic waste that enters the ocean can travel across vast distances through ocean currents, leading to the spread of pollution to remote areas. Plastic debris can accumulate in massive garbage patches, such as the Great Pacific Garbage Patch, which consists of floating plastic debris covering a significant area. These garbage patches not only harm local ecosystems but also serve as a stark reminder of the magnitude of the plastic pollution problem.
  6. Environmental Degradation: The production, use, and disposal of plastic contribute to environmental degradation. Plastics are derived from fossil fuels, and their manufacturing process produces greenhouse gas emissions. Improper disposal and lack of recycling infrastructure result in large amounts of plastic waste entering waterways and ultimately reaching the ocean. Plastic pollution also contributes to the depletion of finite resources and perpetuates the cycle of resource extraction and waste generation.

Addressing plastic pollution in the ocean requires a multi-faceted approach, including reducing plastic consumption, improving waste management systems, promoting recycling and circular economy practices, and raising awareness about the issue. By taking collective action, individuals, communities, industries, and governments can work together to mitigate the problems caused by plastic in the ocean and protect the marine environment for future generations.
