The Ocean's Plastic Crisis: How Did This Happen?

Plastic pollution in the ocean is a pressing environmental issue. About 0.5% of global plastic waste ends up in the ocean, which equates to roughly 1.7 million tonnes per year. The majority of this pollution is caused by littering, with around 80% of plastics entering the oceans originating from land-based sources. Plastic waste flows downstream through rivers and can be picked up by rotating ocean currents, transporting it anywhere in the world. Ultimately, the responsibility lies with us. By reducing the use of single-use plastics, we can tackle the issue of ocean plastics at its source.

Plastic waste from land-based sources

Littering is a significant contributor to land-based plastic waste, with disposable plastic items such as food wrappings, plastic bags, razors, and bottles not being disposed of properly. These items can break down into microplastic particles, which flow downstream through rivers and are picked up by rotating ocean currents, transporting them worldwide.

In addition to littering, industrial activities and inadequate waste management practices contribute to land-based plastic waste. Corporations must take significant steps to reduce the sale of single-use plastics and encourage the use of reusable alternatives. By reducing the use of light, single-use plastics, we can decrease the amount thrown away and potentially ending up in the ocean.

Personal care and cosmetic products also contribute to land-based plastic waste, with items such as toothpaste, wet wipes, shower gels, face scrubs, and sanitary products containing microbeads – tiny plastic particles that end up in waterways and oceans. These microbeads are often too small to be filtered out, further contributing to the plastic pollution in our oceans.

Solving the ocean plastics crisis requires addressing these land-based sources and implementing better waste management practices and infrastructure. By reducing plastic waste at the source and improving disposal and recycling methods, we can decrease the amount of plastic entering our oceans and protect marine life from the devastating effects of plastic pollution.

Inadequate waste management

The plastic that ends up in the ocean comes from a variety of sources, including littering, industrial activities, and fishing gear lost at sea. However, the majority of plastic pollution in the ocean is caused by land-based sources, with only a small fraction originating from ships. This is due to the fact that most plastic waste flows downstream through rivers and can be picked up by rotating ocean currents, called gyres, which can transport it anywhere in the world. For example, scientists from National Geographic found plastic from Russia, the United States, Europe, South America, Japan, and China on Henderson Island, an uninhabited isolated atoll halfway between Chile and New Zealand.

In addition to inadequate waste management, the use of disposable plastic items is a major contributor to the problem. Items such as food wrappings, plastic bags, razors, bottles, and personal care and cosmetic products often contain microbeads, which are extremely small plastic particles that end up in waterways leading to the oceans. By reducing the use of light, single-use plastics, we can decrease the amount of plastic waste that ends up in the ocean.

To tackle the issue of ocean plastics, it is important to address the problem at its source. This includes improving waste management systems and infrastructure, as well as encouraging corporations to take significant steps to reduce the sale of single-use plastics. By working together to reduce plastic pollution, we can help protect marine life and preserve the health of our oceans.

Industrial activities

In addition, microplastics, which are tiny plastic particles, can be released into waterways through industrial processes. These microplastics are often found in personal care and cosmetic products, such as toothpaste, wet wipes, and face scrubs, and can be washed down drains and end up in the ocean.

The impact of industrial activities on ocean plastic pollution is significant, with an estimated 0.5% of global plastic waste ending up in the ocean each year, according to recent estimates. This amounts to approximately 1.7 million tonnes of plastic waste entering the oceans annually.

To address the issue of ocean plastic pollution from industrial activities, it is crucial to implement proper waste management practices and reduce the use of single-use plastics. Corporations and industries have a responsibility to reduce the production and sale of disposable plastic items and invest in sustainable alternatives. By tackling the issue at its source, we can make significant progress in combating the environmental crisis caused by plastic pollution in our oceans.

Rivers

The plastic that ends up in rivers comes from littering, inadequate waste management and industrial activities. Rivers in regions lacking proper waste infrastructure are particularly susceptible to plastic pollution. According to the UN Environment Programme, roughly two billion people globally lack access to solid waste collection services.

Personal care and cosmetic products, including toothpaste, wet wipes, shower gels, face scrubs, and sanitary items, contain microbeads – extremely small plastic particles that end up in waterways leading to the oceans.

Solving the problem of plastic in the ocean requires addressing it at its source. This includes corporations taking significant steps to reduce the sale of single-use plastics. By reducing the use of light, single-use plastics, we can decrease the amount thrown away.

Microbeads in personal care products

Plastic waste in the ocean is a pressing environmental issue. About 0.5% of global plastic waste ends up in the ocean, which equates to roughly 1.7 million tonnes per year. The majority of this plastic waste comes from land-based sources, with 82% of plastic waste entering the oceans flushed through rivers.

Microbeads are a type of microplastic that is found in personal care products such as toothpaste, wet wipes, shower gels, face scrubs and sanitary items. These microbeads are extremely small plastic particles that are washed down the drain and end up in waterways leading to the oceans. Once in the ocean, they can be transported by rotating ocean currents, called gyres, to anywhere in the world.

The use of microbeads in personal care products contributes to the plastic waste crisis in the ocean. These tiny plastic particles are not easily filtered out by wastewater treatment plants, so they end up in the ocean where they can be ingested by marine life. Over time, the microbeads can break down into even smaller particles, which can then be consumed by smaller organisms and work their way up the food chain.

To address the issue of microbeads in the ocean, some countries have implemented bans or restrictions on their use in personal care products. For example, the United States passed the Microbead-Free Waters Act in 2015, which phased out the use of microbeads in rinse-off cosmetics. In the United Kingdom, a similar ban was implemented in 2018. These measures aim to reduce the amount of microplastic pollution in the ocean and protect marine life from the harmful effects of ingesting plastic particles.

It is important for consumers to be aware of the presence of microbeads in personal care products and to choose alternatives that do not contain plastic particles. By reducing the use of single-use plastics and properly disposing of plastic waste, we can help to tackle the issue of ocean plastic pollution.
