According to experts, in this case, our bodies and the world as a whole will change dramatically. The consequences will be both negative and positive.
Each of us once dreamed of owning wings that we could use for a variety of purposes. But what if humans actually had wings? What would happen to our bodies then? The experts explained, writes The Grunge.
For humans to be able to fly, our bodies and the world will have to change drastically. People will build flight-friendly buildings and develop technologies to fit our new bodies. But that's not all. Many everyday aspects of human life will also change forever, some for the better, others for the worse.
The first fact to know is that flying requires a lot of energy, and the more weight, the more gravity will pull you down. Therefore, most likely, many people will perceive flying as an additional means of transportation and will still prefer to walk, ride a bike or drive a car.
There are many features in the bodies of birds that allow them to fly. First, their bones are lighter and their wingspan is balanced with their body size. Since humans are big, we will need to have a wingspan of around 7m to take off. But we will not be able to flap our wings and take off like a normal bird, we will most likely need launch pads.
Birds also have strong chest, the pectoral muscles of hummingbirds account for up to 25% of their total mass. Simply put, we will have to be stronger than bodybuilders.
What else will change in our body is the structure of the bones. Since human bones must be light and fragile in order to fly, we must have stronger clavicles in the form of the thymus, as well as a keel – an outgrowth of the sternum of vertebrates, to which strongly developed pectoral muscles are attached.
As mentioned, even if humans could fly, we would still need roads and transportation systems. The architecture and map of the city will change a lot, and the demand for delivery will also increase.
As far as flight itself goes, humans are too big to take off spontaneously from the ground, flapping their wings like birds do. In fact, we need some kind of power behind us. So, for example, a bird that lived almost 6 million years ago – argentavis, was about the same size as us, and in order to fly, she had to run down a slope against a headwind. Because of this, airports, homes, and most public places will require a dedicated take-off space.
If people could fly, not only our environment would change, but our society as a whole, including fashion. Heels will become less popular as they are harder to land in, and skirts and dresses will need to be created with built-in shorts. People will also have to wear goggles and helmets to protect their eyes and heads from bugs, debris and everything else.
Along with increased tracking, there will also have to be more control. Most likely, politicians will pass new laws against peeping, flying robbers, trespassers and air pollutants. Unfortunately, people are notorious for destroying everything they touch, so the sky will be no exception if people spend a lot of time there.
Although the likelihood of air pollution would increase if people started flying, this would also reduce the need for ground transportation. Cars emit about 3000 kg of carbon dioxide per year, and if people fly from place to place, there will be fewer cars on the roads. In addition, people can fly to pick up their goods and packages, further reducing shipping emissions.
