Are Giant Insects Larger Than Humans Possible?

The video explores the possibility of giant insects, focusing on the limitations of exoskeletons and the role of oxygen in determining insect size. It discusses how larger exoskeletons would be inefficient and how oxygen levels 300 million years ago allowed for larger insects. The evolution of birds and bats also contributed to the decrease in insect size. Despite their small size, insects have impressive adaptations and social structures.

How do insects breathe, and why does this limit their size?

What happened to the size of insects when birds and bats evolved?
