I agree. The plastic that will end up in landfill is the utterly insane amount of wrapping that that so many everyday goods come in. I saw a pomello in the supermarket recently wrapped in a plastic net, over a plastic cling wrap. 1 pomello, a bloody citrus fruit that comes in it's own naturally grown, really thick and protective, 100% compostable, wrapping. WTF! It didn't need any wrapping at all and it had two layers of plastic around it. It was sickening.
On the otherhand my DS has quite a lot of plastic toys. Really phenomenally sturdy, well made plastic toys. About 70% were bought secondhand and were perfect when I bought them. They have seen years of play, will see years more, and when he's outgrown them, I plan on storing them for any grandchildren/nieces/nephews I might have. And they will be perfect then too. Or, if I ever do need to get rid of them, they're in high demand and would sell quickly to people who would care for them and store/sell them on in the future.
Some toys are clearly landfill crap though, cheap nasty plastic that will break in no time. Stocking fillers, a lot, but not all, of the poundshop toys, some blindbag nonsense, party bag shite, etc. Brittle plastic, poorly made, will break in weeks if not minutes, has very little longevity of play etc. I never buy those. At Christmas I do like to do a stocking as I love the tradition of hanging it to be filled So I bought a really big one and I put proper toys in it. Nearly everything that would be given as a surprise to compliment the main gift gets chucked in the stocking if it fits. (A Joker vehicle and figure to go with the asked for Batcave for example.) Well chosen gifts that I want to give him because I know they will be loved hugely and last forever (in the good way) nothing goes in just for the sake of filling a stocking or bulking it out.
I do a lot of toy repair and customisation, so on the rare occasion where a toy I bought gets damaged I can fix it or save the parts to turn it into something else. So none of those toys should ever find themselves in landfill. There is very little i can do with some of the crap other people give him though. They are unwanted rubbish. I don't think a lot of it is very recyclable and I hate when people give them to him. I'd rather he gets nothing than total crap. As for Happy Meal toys, yup, these days most of them are excellent toys with good playability and even resale potential (we have loads of McDonalds' toys bought secondhand). But they do still give out some total crap too. This year for example they had a Justice League range and the "toys" were honestly just pointless. They didn't have any real playablity and were just hard lumps of plastic manufactured to be discarded.
