Plastic

Microplastics are particles smaller than five millimeters in length, or narrower than a pencil-tip eraser. 

Microplastics Are Swirling Around in the Atmosphere, Where They Might Be Contributing to Climate Change

Airborne plastic particles, particularly colorful ones, absorb more sunlight than they reflect, which can heat the surrounding air, according to a new study

Microplastics pose a growing global concern as they infiltrate not just the environment but also humans and animals.
