Based on several videos I’ve seen in the past Ecosia is mostly greenwashing. Not sure if they recently changed something in their business practices but apparantly they planted vast amount of monoculture trees in relatively small areas. Thus, the majority of the trees just died due to lack of light, water and nutrients.
Art is not even exclusive to human-like species in general. Just to give an example, check out the mating ritual of puffer fish.

If fish show an interest in creating visually appearing structures, why should it be any different for early primates? I would rather expect that more or less each species has individual forms of art. Although we as humans might not be capable to understand them.
How do we know if a dog peeing in the park is really just marking the area as its own? What if they’re on purpose creating some kind of smelly art for their fellow doggos?
