I'm someone who is concerned about plastic pollution, and particularly concerned about ingesting it. I don't microwave my food in plastic dishes, and I use stainless steel insulated mugs, and I went out of my way to find teabags made without plastic. But the research results in this area were definitely exaggerated by the media. Here's an example:
One of the studies that looked at microplastics in the brain was conducted by taking brain tissue and using a chemical process to dissolve organic tissue, but then the researchers didn't really analyze the composition of what was left. They just assumed that all the remaining material was probably plastic. That's how you got the famous claim that there's *up to* a teaspoon full of plastic in your brain, which is an extraordinary claim and requires extraordinary evidence, in my opinion. In reality the method they used doesn't provably dissolve all brain tissue, so there's probably elements left over, and that's most of what was measured. But that didn't stop the media from grabbing the headline and running with it.
The nicest thing about the Alto is that it doesn't run faster at night.
