Tire dust makes up the majority of ocean microplastics (thedrive.com)

Article summary

A recent study found that tire dust makes up the majority of ocean microplastics, with 78% of ocean microplastics coming from synthetic tire rubber. The particles from tire wear can cause neurological effects, behavioral changes, and abnormal growth in marine animals. The issue is not limited to ocean microplastics, as tire dust can also have negative health impacts on humans. The problem is expected to persist even with the transition to electric vehicles, as they tend to shed more tire dust due to their higher weight and torque.

What commenters say

• The focus on EVs is a distraction from the real issue of tire dust pollution, which affects all vehicles.
• EVs may actually reduce brake dust due to regenerative braking, but this does not address the tire dust problem.
• Natural rubber tires could be a solution to the problem, but they are not widely used due to being slightly more expensive.
• The root of the problem lies in the built environment and urban planning, which prioritizes car-centric infrastructure over walking, biking, and public transportation.
• Infrastructure changes, such as safer streets and bike lanes, could make cycling a more viable option for short distances.
• The distance people are willing to walk to a store varies greatly, and some people would prefer to walk or cycle rather than drive.
• The use of synthetic rubber in tires is driven by profit motives, and a shift to natural rubber could reduce pollution.
• Government regulation and funding could play a crucial role in addressing the issue of tire dust pollution.
