I'd say a group of scientists studying plastic products
right off the bat cross out A catalog of plastic products and A company trying to sell plastic products.
Now 50 50 here a group of activists against using plastic products is pretty good but if you think about it says that their AGAINST using plastic products so they may just be biased and say more about the disadvantages to convince you to not use it again but however a scientists are studying it their telling you both sides so yea
hope that helps alrighty bye now
