Editor’s note: “MMA is methyl methacrylate, a chemical compound that was banned by the FDA in the 1970s for use in nail enhancements due to its potential health hazards,” Hanna says. Celebrity manicurist Julie Kandalec adds, “It’s an ingredient commonly found in acrylic liquids, called monomer.”

One of the easiest ways to check if there is MMA in your acrylic or nail supplies is to check the ingredient list of your products. It should not be listed as an ingredient in any reputable acrylic nail product. A few additional tips include: Smelling a very harsh odor when applying and filing your acrylic nails - some people say it smells like cat urine.

Editor’s note: A new report that microplastics pollution is hampering photosynthesis in plants, and that the result is the loss of some 10% of the world’s primary productivity, including food crops. We are now risking to blot out the planetary photosynthesis machine, just because we think that stopping the growth of the plastics industry is a subversive idea. But the report gets something in reverse: it is not that these effects “extend from food security into planetary health.” It is the opposite .But that changes little in a situation in which nothing changes, except for the desperate attempt of solving problems by killing the messenger, that is, " driving a dagger into the climate change religion"

Editor’s note: “A new study in Science indicates that reforestation projects, which restore degraded or destroyed forests, are the most effective land-based method for carbon removal and biodiversity protection. Meanwhile, the authors found that afforestation, in which trees are added where they didn’t exist before, and bioenergy cropping, in which carbon-removing crops are planted to make biofuels, can have negative effects on wildlife, outweighing the benefits of carbon removal. The research highlights the importance of identifying the best places for reforestation projects, but the authors emphasize that reforestation is not a replacement for fossil-fuel reduction.”
