Very fun game, likely spent too much time playing it.
One quick note: I think it's a bit too easy to go infinite. With radiant refuge, I can pretty consistently do it on the fourth month, but I have got it turn 3. By searching in south America, it's reasonably easy to find the cards you need:
2 birds, for resources without taking actions (penguin, macaw)
multiples of either tamarin, each of which draws extra cards without costing actions. Eventually you can draw you deck and just loop with monkeys.
llama, which gives 2 actions
black legged poison dart frog, which allows you to pull all other cards from your deck
Spectacled bear, which gives you more ecology
With 2 birds and 2 tamarins, you have infinite money, happiness and science. With Llama and bear, you also have actions and ecology. Using that you can fish in Africa for gorilla, which gives you infinite guests (while scoring them so as to not overload your deck), bypassing tickets entirely. One of the Camels from Eurasia lets you refresh the shop until you find whatever other staff/facilities you want. In this way, you can complete any objectives instantly. Frog and social media team stripes everything else to keep you functional. Beaver lets you draw your deck every turn, donkey keeps you form having to reset them every two turns.
Because all the core cards for the loop are in South America, you can fish in that one zone with your first 6-8 science and usually get enough to start the loop. Once you have it going, resources become irrelevant. Eurasia and Australia have other birds that can complete the loop (and Australia has a llama alternative), but if you split up the card draw cards and gave them to an animal in Africa or North America, I think it would be much harder to pull off the loop.
