In recent years, microplastics have become a hot topic in the world of environmental conservation. These tiny particles, often measuring less than 5mm in size, are causing a significant amount of harm to our planet and its inhabitants. But what exactly are microplastics, where do they come from, and what impact are they having on our world?
First, let’s define what microplastics are. Simply put, microplastics are small pieces of plastic that have broken down from larger plastic items. These particles can come from a variety of sources, including plastic bags, bottles, and packaging materials. Microplastics can also be created from larger plastic items that have been broken down by the sun and waves in the ocean.
One of the most significant sources of microplastics is from personal care products. Many toothpastes, exfoliating scrubs, and body washes contain microbeads, which are tiny plastic particles that are washed down the drain and end up in our oceans and rivers. According to a study by the Environmental Science and Technology Journal, 8 trillion microbeads are released into US waters every day (Rochman, et al., 2015).
Another major source of microplastics is from the breakdown of larger plastic items in the ocean. Plastic bags, bottles, and packaging materials often end up in the ocean, where they are broken down by the sun and waves into tiny particles. A study by the University of Georgia found that by 2025, there will be more plastic in the ocean than fish by weight (Jambeck, et al., 2015).
The impact of microplastics on the environment is significant. These tiny particles are ingested by a variety of marine animals, including fish, birds, and even whales. According to a study by the Marine Pollution Bulletin, over 50% of sea turtles and nearly all seabirds have ingested plastic (Eriksen, et al., 2014). Microplastics can also absorb toxic chemicals, which can then be passed up the food chain to animals and even humans.
But the impact of microplastics isn’t just limited to marine life. These tiny particles are also found in tap water, bottled water, and even beer (Mason, et al., 2017). A study by the World Health Organization found that microplastics have been found in human feces, raising concerns about the potential health risks (WHO, 2018).
So what can we do to combat the issue of microplastics? One solution is to reduce our use of single-use plastics, such as plastic bags and bottles. Another solution is to support companies that are phasing out the use of microbeads in personal care products. We can also support research and development of technologies that can effectively remove microplastics from our oceans and rivers.
Microplastics are a growing problem that is having a significant impact on our environment and potentially our health. It’s up to all of us to take action and reduce our use of single-use plastics, support companies that are phasing out the use of microbeads, and support research and development of technologies of microplastics removal efforts.
