Elon Musk has again warned the public about the dangers ahead. What exactly are these dangers, and how much damage can they do?
According to Musk, there's a lot going on that people don't realize is happening. Elon Mosk believes the world's birth rate is too low and has renewed his call for people to have more children in order to save civilization. Some people think having fewer children is healthier for the environment, which is ridiculous! But it turns out the world would be better off if we doubled the number. Musk suggested that we keep our numbers growing at the same rate 39bet-xì dách-phỏm miền bắc-tiến lên miền bắc-xóc đĩa-game bắn cá. We don't have to expand fast, but we must avoid gradual decline until society collapses. But Musk didn't provide any evidence to back up his claim!
According to one study, having one fewer child per household in rich countries might reduce carbon emissions by about 58.6 metric tons per year. Some experts argue that delaying childbearing could have a bigger impact on the environment than lifestyle changes and the simultaneous adjustment of climate regulations. Musk believes that if people stop having children, the human race will die. Back in December, Musk raised a warning, declaring that civilizations would die if people didn't have enough children, such as Japan, which could cease to exist due to its low birth rate. The UN's latest World Population Prospects report says the world's population is projected to increase from 7.7 billion in 2019 to 9.7 billion by 2050.
But in fact, it's not unusual for birth rates to fall during recessions. For example, the rising cost of living in the United States has led many Americans of this generation to delay childbearing. The reasons for population decline also include: the negative impact of population expansion on the environment due to gender inequality, restrictive immigration policies, and the high cost of childbearing are typical arguments against childbearing. Representative Alessandro Ocasio-Cortez says some individuals choose to have no children or fewer children to reduce the environmental burden.
Musk, on the other hand, said that since the expansion of the sun could lead to the extinction of all life on Earth, it would be necessary to live on other planets, so as to increase fertility. But experts say the world has experienced five mass extinctions and is currently experiencing a sixth. The current mass extinction is entirely the result of human actions, not natural causes. The first five were devastating natural disasters, and 260,000 species, including invertebrates such as snails and slugs, may have gone extinct since 1500, according to the study.
Of course, the expansion of the sun is also a threat, as our sun runs out of hydrogen to burn, it expands and engulfs the Earth, and as Musk pointed out in his tweet, this expansion puts all species on Earth at risk. While Musk's prediction is correct, the sun has been expanding for much longer than the current rate at which millions of species are going extinct. Elon Musk has warned humans to leave Earth because it is becoming less and less suitable for human life. He hopes to establish a colony on Mars.
Musk is also concerned that Earth could be hit by an extraterrestrial asteroid. In February 2013, the Russian Jeria Banks meteor struck Earth, entering the planet at a shallow angle and traveling at 60 times the speed of sound. When it comes into contact with its surroundings, it explodes in the air. The meteorite was about 20 meters wide and weighed 13,000 metric tons. After burning and breaking, it injured 1,000 people and destroyed about 20,000 buildings, but if a bigger meteorite appeared, would we be able to defend against it? The answer is basically no, of course, depending on the size of the item and the location of the asteroid that was hit. After all, melting or destroying a very small asteroid is currently beyond the capabilities of current technology.
But I think Musk's concerns are unfounded. Earth has a moon, which greatly reduces the possibility of an asteroid impact, and Mars, which has no magnetic field and is not habitable, is not realistic at all. What do you think?
