Plastics are part of our lives and only by difficult means or expense will we stop using it. I would like to boycott it because of it being made from petroleum and because of the possibility of the chemicals leaching into what we eat or drink. But, hey, as some of my friends used to say, "She is the Tupperware queen!" Lots of my plastic I acquired by giving parties and getting free gifts! I have retired some of it for a while, being I am not using the microwave as much, but I have much storage in the containers and I am not throwing them out!
So, I will not stop using it, but I will check the recycle codes first. According to what I researched, 'they' say if it is a #2 HDPE, or a #4 LDPE, or a #5 PP, plastic is ok to use.
Plastic water bottles (and drinking cups) is most often #1. #1 is for one time use. I've started throwing them out ... or as I have read, refill it no more than once. Of course, with the newer, thinner eco bottles, I am using them as “luxury items' when we are out and about and tossing them, because they 'taste plastic' to me the first time.
I am not going to give any links. If you are curious do a search for yourself and satisfy that curiosity. Like most other things, every person does not agree and it can get confusing.
