The traditional tree here is a fir. In my childhood I would listen to my mum complaining about the needles and what to do with the fir after Christmas. In my teens I became aware of environmental issues. I began to see the tree as a symbol of a destructive consumer culture. I came up with a solution: let's decorate our potted palm! I ran my campaign for a few years and finally my mum gave in. My main argument was that the palm tree actually represents the original Christian Christmas better: you know mum, Jesus was born in Israel and they had palm trees there, not firs. Decorating the palm tree tradition lasted about three years. As far as I could understand, my mum was happy about the palm tree solution, she would say how it was so much easier. Then I went to college and moved out and they returned to buying a fir... guess it just didn't feel like Christmas to them without it.
In our homestead we cut a fir tree, but it really doesn't have many downsides here. We cut a small fir that would have to be cut anyway. We need to thin our woodland to allow for better growth and to remove some of the firs so they don't take over the whole woodland. We want it to remain a mixed wood: conifers and deciduos trees. In our climate, if we do nothing, firs and pines will take over and that would reduce the biodiversity.
After Christmas, the tree gets chopped and becomes firewood or material for a hugelbed.
About the Christmas present dilemma then... I can only offer my sympathies! I haven't come up with a complete solution to this one.
For the adults I give our farm's products: eggs, honey, dried lavender, garlic. But the kids... they really don't enjoy "useful" presents. Up until now we've just given them plastic China-made toys, because it makes them happy. But now most of the kids in our extended family are teens or approaching their teens and the only thing on their wish list is money or gift cards (which is the same thing from the present-giver's perspective). Now that is a real problem, because we simply do not make enough money. Giving a sum that they would consider a present is a much bigger thing for us than they realize: we actually have to sacrifice something really important to us to be able to give 20 euros for each of our children's cousins and our friends' kids. Anything less than that and they look at you with empty eyes and say "thanks", obviously wanting to add "you cheapskate". Giving 20 euros each equals to 220 euros as there's 11 kids. And most of our relatives give 50 euros, 20 e is considered "candy money". I guess our relatives are just too rich for us

I can't really decide whether to stick to "give what you can" philosophy and give 10 euros each or to just accept the fact that we can't really give them what they want and just give something else altogether, like poems or something immaterial.
