Food: a pile of veg; beef joint; fruit; stuff to make Christmas pudding; stuff to make mince pies; ice cream.
Three desserts/sweets? Four, if you count the fruit. That's unnecessary. You probably don't NEED all the veg and fruit you buy either. Even if you do eat it all, you'll be stuffed and overfull. You don't NEED beef either. Chicken would be cheaper and less excessive. Vegetarian or vegan would be better yet, especially for the environment.
Presents: second-hand things - lego, puzzles, books, pencils, pyjamas, socks. Stuff I've made - individual christmas cakes. Things I've bought new - books, socks. I'm also giving some experiences, like lessons for things my kids want to learn.
Gifts are unnecessary. Nobody NEEDS gifts, even if you did indirectly contribute to consumerism consumerism by buying stuff that someone else bought already. And you bought stuff new, too! You can get books from the library. And was there any plastic in any of this stuff? And what are these experiences, will they involve any emissions, even just to get there, or any wastage? Anyway, who NEEDS to go go karting or glass blowing or whatever?
More Christmas cakes? So that's four, or maybe five, sweet things that nobody NEEDS?
Would it be OK for people to buy decorations if, unlike you, they didn't buy them already?
So much that you don't NEED!
