The threat of microplastics and what to do about it

What are microplastics?

Microplastics are tiny plastic particles smaller than 5mm in size. They are mainly divided into two types:

1. Primary microplastics : These are small particles that are produced from the start (e.g. facial scrubs, plastic microbeads, etc.).

2. Secondary microplastics : Small particles that result from the degradation of plastic products such as PET bottles and shopping bags.

   
   

Although these are hard to see, they are spreading through oceans and rivers around the world, causing serious environmental problems.

The environmental impact of microplastics

The impacts of microplastics on the environment are manifold.

• Effects on marine life : Fish and shellfish may accidentally ingest it, causing digestive upset and nutritional deficiencies.

• Impact on the food chain : It can accumulate in the bodies of birds and mammals that eat seafood, and even humans.

• Spread of chemicals : Microplastics are prone to attaching harmful chemicals, which impacts ecosystems.

• Water pollution : As it is difficult to decompose, it continues to pollute water for a long period of time.

What we can do

There is a lot we can do to address the issue of microplastics.

1. Reduce single-use plastic

   • Use eco-bags and reusable bottles.

   • Eliminate plastic straws and use metal or paper alternatives.

2. Proper disposal and recycling

   • Thoroughly separate plastic waste and recycle it appropriately.

   • Recycle wherever possible before discarding.

3. Choose environmentally friendly products

   • Use cleansers and toothpastes that do not contain microbeads.

   • Purchase products made from recycled plastics.

4. Participate in beach cleanups and environmental conservation activities

   • Participate in volunteer activities and pick up trash on beaches and in rivers.

   • Spread the word about environmental issues to those around you and encourage awareness.

5. Lobbying companies and governments

   • Support companies that promote environmentally friendly policies.

   • We call for stronger laws and regulations to reduce plastic.

Microplastics are generated in our daily lives and have a serious impact on the environment. However, by changing our awareness at the individual level, we can reduce their generation and build a better future. SUSTAINABLE JAPAN and UPSEA continue to work toward solving environmental problems. Why not start doing what you can today?
