What if there were no seasons?

If Earth’s axis weren’t tilted, there would be no seasonal variation, and humans would be confined to the continuous warmth of the planet’s mid-section. We most likely would never have developed advanced agriculture, as most staple crops require cold winters, and would constantly be plagued by horrific insect-borne diseases. Forget the Industrial Revolution and the modern conveniences that sprung from it: Much of our technology has its roots in the existence of winter, because it is a by-product of inventions of new and better ways to keep warm.

I don’t think we could know what kind of climate, animal, or plant variations would have existed if this were the case. Yes, we would not have agriculture as we know it today but I think it’s wrong to say that we would not have any agriculture or advancement in technology. Plus this person seems to assume we’d only have gross humid tropical areas or permafrost tundra to live with and bases all climate forecasts on what currently exists in a seasoned/tilting world which again, might not be true.

It would be a completely different system with a completely different set of variables.
