Please share some relevant links. I am not saying that animals are dumb, I am trying to highlight the difference between pain and suffering here.

Think of a kid! They have minimum suffering which arises out of basic needs like food, sleep, etc. Our world today has prevalent suffering but this wasn’t the case always. Suffering is mostly constructed by human brain with the help of language and thoughts around pain. Think of animals! They have pains, sometimes, but they don’t suffer because they don’t have to think of past or future and just stay mindful, mostly always. They don’t have words like “suffering” and “pain” and “what would others think” or even a sense of self.

Most philosophers propose that shedding of the identity can remove all sufferings.

Today, major sufferings are a result of mental constructs rather something tangible. We can and definitely will solve them easily in a few thousand years which is a small period of time, on the scale of universe.
