Upon hearing this, Bi Qiaoan was so shocked that she put down her chopsticks.
Shen Yanming was also somewhat surprised, not expecting that impetigo would develop in this way.
This situation is rather complicated; I'm afraid it can't be resolved by human effort alone.
Seeing the fear in everyone's eyes, Dean Xu continued, "Let's move on to the second thing, which is that this change in sunlight has triggered natural selection."
Amidst everyone's puzzled looks, he slowly said, "Recently, we have received many reports that 'the food is bitter.' This includes bitter rice, bitter noodles, bitter vegetables, bitter fruit, and even bitter meat."
Our researchers from various city branches conducted on-site investigations overnight and ultimately discovered that all bitter foods were related to this year's unusual sunlight.
Have you noticed that when harvesting wheat, many plants are withered? And when harvesting vegetables, many leaves are also withered?
And many of those fruits, some not yet ripe, or just ripe, fell off the tree trunks and landed on the ground without any visible wounds.
These are the sources of bitter foods that have been recently reported.
Because plants undergo natural selection, eliminating those that are not adapted to new living environments.
Those that remained were the species that adapted to the mutated sunlight.
Dean Xu gestured to his assistant to project the photos and videos of plants and animals collected by the researchers from various locations onto the screen.
Pointing to the withered wheat and rice in the video, he said, "The more discarded plants you mix into your cooking, the more bitter the food will taste."
This explains why some people have recently discovered that newly harvested grain tastes bitter, while others haven't noticed the bitterness.
Dean Xu pressed a button on the remote control, and the screen switched to another display.
"This phenomenon is not only reflected in plants, but also in animals, including humans."
Have you noticed that there are far fewer mosquitoes this year? Compared to last year, it's so much better.
But is all of this really thanks to last year's special insecticide? Probably not!
As creatures that have thrived on this planet for hundreds of millions of years, how could we possibly be nearly driven to extinction by mere pesticides? Don't you agree?
Seeing everyone nod, Dean Xu continued, "This is because the little insects had no protection and could not survive under the mutated sunlight, so they died one after another. That's why everyone felt that these little things suddenly disappeared."
However, those that remain are the ones that can adapt to the mutated sunlight.
In the future, their reproductive capacity may increase, and their blood-sucking ability may be several times that of ordinary mosquitoes.
Therefore, there are some things that need to be prevented in advance.
Of course, these are just our speculations, and we'll need to observe further to see how things unfold. After all, science is based on data.
Dean Xu then showed some photos of poultry and livestock, saying, "Since most of the poultry and livestock are artificially raised indoors, they are not greatly affected."
However, many are raised outdoors.
In this way, by comparison, we can find that many chickens, ducks, geese, pigs, cattle, and sheep have started to lose their appetite and become listless.
They don't lay eggs, mate, or even make noise; all because they can't adapt to changes in sunlight.
Although he is still alive, he is not far from death.
As for the wild animals in the wild, they are in a similar situation.
The strong and healthy become the elite of the tribe, holding leadership positions. The weak, on the other hand, are abandoned and left to fend for themselves.
This is what is known as natural selection.
Survival of the fittest; only the fittest survive.
Dean Xu closed the projector at this point, looked up at everyone and said, "Some plants and animals have died, and some have survived; these are only short-term effects."
In the long run, changes in population size will inevitably impact the food chain.
And this is something we cannot change. We can only wait for nature to reach a new balance.
It's hard to say what we will face in this process.
Therefore, I suggest that friends who raise poultry and livestock should start now by putting their poultry and livestock in the sun and letting them receive sunlight.
Those that cannot adapt to environmental changes can be appropriately culled. The strong ones should be kept for breeding and propagation.
The same advice applies to plants.
Withered or malnourished plants can be discarded.
When sowing in autumn and winter, seeds should be selected from plants with strong traits to ensure high grain yields and good grain taste in this increasingly deteriorating environment.
Of course, it must be noted here that the mutated sunlight only alters a segment of the genes in plants and animals, causing them to exhibit a poorer taste and a bitter flavor when expressed.
It has no impact on the nutritional structure.
So there's no need to panic. Even grains and vegetables that don't adapt well to changes in sunlight are still non-toxic and edible. They just might not taste very good.
At this point, Dean Xu changed the subject, saying, "Actually, impetigo in humans is also a result of natural selection."
Like plants and animals, we are not adapted to the changed sunlight, which is why we develop pustules on our bodies.
So why do plants and animals not have pustules, while humans develop these unsightly and spreading pustules on their skin?
That's because if a plant doesn't adapt, it will be half-dead or even die.
Animals, on the other hand, have thick fur or feathers that help protect them from the harmful effects of sunlight, so they are less affected.
Only insects, which have no protective measures, will die in large numbers due to maladaptation.
Of course, as I just said, the world needs balance, and once they get through this, their capabilities in various aspects may be strengthened.
At that time, those little insects will be even more difficult for humans to deal with.
Now, let's talk about ourselves. We all know that the skin is the body's primary organ, protecting it from most external harms, including mutated sunlight.
When the skin is injured, it needs an outlet to express its feelings, and that's what pustules are.
We humans are quite interesting, actually.
Despite being one of the least adaptable creatures to mutated sunlight, they have chosen to use various tools to block sunlight or directly alter their biological clock, becoming nocturnal.
Even more advanced technologies could be used to artificially block the harmful effects of mutated sunlight or alter the body's sensitivity to it.
In this way, humanity, through its own wisdom, has become the strongest and survives on this planet.
After Dean Xu finished speaking, everyone wore a relieved smile.
After hearing so much, there's finally some good news.
