Answers
Answer:
The first thing most people notice about birds is that they can fly, but that is not what makes them unique. Bats, bugs, and butterflies also take to the air, and they aren’t birds. What makes birds different from every other kind of animal on earth are feathers. Feathers make it possible for birds to live a large part of their lives in the air. Feathers weigh very little, are strong (to survive long flights), and provide terrific insulation (which is why people living in the coldest parts of the world prefer jackets stuffed with goose down). Most birds also have hollow bones. If bird bones were solid, like human bones, birds would be too heavy, which would make flight very difficult.
Answer:
We cannot create enough lift to overcome the force of gravity. The light frame and hollow bones of the birds make it easier to counteract gravity. Air sacs inside their bodies make birds lighter, which enables smoother motion through air. So as, we are not physically designed to fly, we cannot fly.
I hope that the answer is helpful to you and if yes plz mark me as brainliest answer
