The hunter-gatherers weren't exactly living in Nirvana. They were at the mercy of the elements, the ebb and flow of prey, and so on. Life expectancy and infant mortality was extremely high.

Agriculture provided a more stable food supply and allowed people to permanently settle specific areas instead of being nomadic. It provided the leisure time and specialization to develop medical and scientific knowledge.

It also gave rise to nation states (instead of tribes) and began the process of altering the environment for our own purposes.

But that last is only harmful if done badly or carelessly, or to excess thanks to population pressure. The rise of agriculture has, on balance, been a good thing for humanity.

Yes, hunter gatherers lived simply enough, and were few enough, that their impact on the world was light. But I wouldn't go back to those days. Better to take the best of both worlds and apply the lessons to modern living.
