Mary Kosuth's article on the environmental and public health concerns of plastic pollution should be a wake-up call ("Post-pandemic, plastic is the crisis we face," Opinion Exchange, Feb. 15). The COVID-19 pandemic pales before the enormity of the issue of plastic pollution. Plastics are burned in many countries, releasing cancer-causing, birth-defect-causing, lung- and brain-damaging dioxins and other chemicals into the air that eventually settle on the crops we eat and surface waters we ultimately drink.
Plastics in our oceans break down into microparticles and are in the fish we eat as well as the water we drink and air we breathe, along with toxic chemicals that adhere to these microparticles.
Scientists have linked ocean microplastics with declines in ocean phytoplankton that are a major source of atmospheric oxygen and "sink" for absorbing carbon dioxide, ecological services similar to what our forests provide for all life on planet Earth.
Phytoplankton, along with zooplankton, which are also harmed by microplastics, are the foundation of the marine food chain, the other end of which is threatened by overfishing.
The COVID-19 pandemic and post-pandemic socioeconomic recovery should not distract us from the urgency of addressing the global crisis of plastic pollution, a petrochemical product whose harmful consequences were never considered but that we now must all face.

I have always recycled, learning at an early age in the 1950s because our garbage hauler took away newspapers and flattened cans. Nowadays, most of the food I buy is enclosed in plastic, and it is driving me crazy. I regularly have to refer to both my county's and my hauler's requirements for recycling plastic, yet I cannot keep straight what I can and cannot put in my recycling bin. Many food containers have a number on them and so can be recycled (if that number happens to be on the list), and some other containers can as well. But what about the food containers that aren't on the list? Some plastic film goes in my recycling bin, but what do I do about the film I have enclosed my windows in this winter, as it's not on the list? I compost all of my kitchen waste, along with containers that have the proper biodegradable number on them. Many plastic bags I can take to the grocery store (and don't forget to cut the label off those mailers with bubble wrap). But what about the bags I buy produce in? I recycle everything I can figure out. This means that the preponderance of waste in my trash bin is plastic.
I don't add a lot to a landfill, but what I do add is plastic. I try and I try but can't seem to do enough.

Kosuth's commentary highlights the other pandemic that has gone on for years: plastic pollution. In the ice of Antarctica and everywhere else on the planet, including our dinner plates and drinking glasses, plastic is ever present.
