Throughout the ages, cities have been built underground. They are most often underground for protection but may also serve as a place to live or work. The concept behind underground cities may have originated in Ancient Era Europe and Middle East. They could have been built as a defense refuge, mausolea, storage cellars or storage tanks. They may also be used as transportation in colder climates.
An underground city is a network made up of subterranean areas that are connected via skyways or tunnels. They may be used for transport, as well as access to stores and restaurants. They can also be used as storage or defense against natural disasters. While some underground cities are accessible to the public, others are closed to the public.

FAQ
Have you ever wondered what amount of trash is generated each day worldwide?
According to the United Nations there are more than 25 billion tons of garbage produced each year.
Most of this trash ends up in landfill dumps or incinerators.But what happens when those dumpsters get full? It goes to the United States, where most of it is exported. It then gets dumped in foreign countries, polluting their ecosystems. However, now we know where all that trash goes. Mike Sexton is his name. He is the owner of Waste Watchers. His job involves monitoring the movements and routes of trash trucks across North America. He then reports back to us on what happens next.
Sexton says he finds his job very satisfying. CNN asked Sexton if he thought it was a lot of fun. "We see these big trucks coming through town, so we'll keep following them. "Sexton began to follow truck drivers around 20 years ago.
He stated that he fell in love with the product.
Sexton's favorite story was about a driver who stopped at an abandoned gas station in Los Angeles. Sexton recalls, "The guy was searching for somewhere to put his loads." "He drove down the road to see this building. He stopped and pulled up, then he went inside. "There were two enormous roll-off containers filled with stuff. The man got everything out of the truck and began filling it up again. "Then, he took everything out and started filling up the truck again. There were a bunch of old tires, rags, furniture, mattresses, boxes, bottles, cans, and whatever else. "It was a complete mess. It had been cleaned up before he arrived. There wasn’t trash everywhere."
Why did this happen? It is because the location used to belong to a recycling centre. People who found out about this facility would drive to it to recycle their trash. Sexton explained that they would bring household items and take them to the building. Then, after they were done, they would empty the containers.
You might see this happen hundreds of times a day. The truck can be stopped running if it is so full of junk that it has to come back hundreds of times per week. And eventually, the owner decides to abandon the vehicle.
Trash, however, isn't the only problem facing our planet.As you may have noticed, things are getting worse.According to experts, pollution levels have risen dramatically in recent years.More than half of all water bodies on Earth are polluted.Pollution from industrial chemicals has increased by more than 30 percent since 1980.Even the air we breathe is becoming increasingly toxic.A study by the World Health Organization found that the average person inhales around 100 million particles daily.
Most of these particles are made up of tiny pieces of plastic.Some of these plastics end up in landfills or incinerators. Others end up in rivers, oceans or the stomachss of fish.
Experts warn that if there is no change, the world could soon be facing a food shortage. Experts warn that if we continue to go the same way, we won't make it. However, scientists and most people aren't worried.
What dark secrets can Hollywood keep from you?
Hollywood is full of secret societies. Some are cult-like groups where members follow strict rules and rituals, while others are simply clubs for those who share common interests.
There are also other, more evil organizations that control large parts of the industry. These include companies like the MPAA ("Motion Picture Association of America"), which determines film ratings. The RIAA ("Recording Industry Association of America") sets music licensing fees.
Numerous unions, guilds, and associations represent actors, writers, producers, editors, and other creative professionals. These large corporations control the majority of major film studios and television networks.
The point is that no matter how secretive any group may seem, someone somewhere knows exactly what they do. We shouldn't fear these people.
Instead, we should embrace and celebrate them. Because they can help us make better decisions.
These people tell us what movies and songs will succeed, and which books will sell best.
They allow us to make informed decisions about what we buy, watch and listen to.
We can trust them so we can ignore their advice when it doesn't suit our taste.
Because we have chosen to ignore their power, they are even more powerful. They are the ultimate judges of taste.
You are free to ignore their messages if that bothers you.
Let's take a closer look at some of the less-known, yet still very real Hollywood secret clubs.
Observe why they are important.
Is there any Hollywood blacklist for actors?
There is an Hollywood blacklist.
However, the list isn’t public. The names are not known to us. Here's why this matters.
The reason behind the secrecy was that blacklisted directors and actors wouldn't be able find work. Thus, they would leave the industry and studios will lose money. That would result in a reduction in spending on movies. This would lead to fewer opportunities and less money for blacklisted directors. They could go bankrupt.
This could mean more victims.
A contract may be required to agree to not speak against employers if someone attempts to make an Oscar winning movie. The same goes for any director or producer who wants to get nominated for an award.
It's no surprise that directors are often forced to take out scenes in their films by producers. Directors threaten to abandon projects that don’t conform to their vision.
This is why Hollywood has created a blacklist. Negative comments about your employer will most likely lead to you being unemployed. That's bad for everyone.
It is not uncommon for people to be falsely accused. They've had the toil to clear their name.
This is unacceptable behavior and must be stopped. Everyone should have the right to speak freely.
Therefore, it is necessary to eliminate the Hollywood blacklist.
