Science Story: 7 objects made by humans that are thought to be creations of nature

According to the scientists, nature untouched by humans is now almost gone. Hard to believe? Then take a look at this list of man-made things you thought were natural.

#1 Lemons

When life give you lemons... As it turns out, life would never give us lemons if it wasn't for us. Lemons are not naturally occurring – they are hybrids of citron and bitter orange. Telling the truth, most citrus fruits we know and love are hybrids: natural citruses are only the pomelo, papeda, mandarin, and citron.

#2 Dogs

Science Story: Dogs as we know them today emerged 20,000-30,000 years ago as the result of domestication of the gray wolf — pixabay pixabay

Dogs are our best friends, but where do they come from? There are no wild dogs – the species of animals named "African wild dogs" doesn’t belong to the same family as our pets. The closest relative of dogs is the extant gray wolf, which was domesticated by prehistoric people, which resulted in the emergence of dogs as we know them today 20,000-30,000 years ago.

#3 Diamonds

Science Story: Synthetic diamonds made in labs look the same to the naked eye — pixabay

Most diamonds found in stores are natural, but, in fact, synthetic diamonds made in labs look the same to the naked eye. They are grown by placing carbon under high pressure and high temperature, which forms a diamond crystal. Are there any significant differences between natural and man-made diamonds? Well, the ones created by nature are more than 3 billion years old, while synthetic ones are quite "young".

#4 Pearls

Science Story: Pearls created without human intervention are extremely rare. Pearls grown on farms make up almost 100% of the pearls available on the market. — pixabay

Just like diamonds, pearls can be manufactured. Anyway, while most diamonds we can buy are natural, pearls created without human intervention are extremely rare. Pearls grown on farms make up almost 100% of the pearls available on the market.

#5 The smell of gas leaks

The smell of gas we use in household is not natural. This distinct odor is added for us to detect gas leaks. In nature, such gases are odorless.

#6 Smog

This word is a combination of "smoke" and "fog", and while fog is a natural phenomenon, smog has nothing to do with it. Smog is visible air pollution which is caused by industrial and vehicular emissions.

#7 The Amazon rainforest

This area is often seen as an environment untouched by humans, but many modern scientists believe that the Amazon Basin had been altered by millions of people who lived there for more than 8,000 years. Some parts of today's rainforest have only grown a few centuries ago, when the ancient civilizations were wiped out by the Europeans.

Did any of these facts surprise you? Would you add anything to this list?

The smell in gas is artificially added, to make it smell like coal gas which does have a natural smell. When we changed to Natural gas there was no smell so an artificial agent was added to make it smell like coal gas, such that people could smell leaks.

This is a fun game real Education for all..kudos

That was pretty cool. I love Pearls. They are so classy. Even Cultured Pearls are expensive, but not as expensive as Natural Pearls. 😊

Right now, the main thing that people are concerned with that are man-made is plastics, a compound that doesn't break down to be re-claimed by nature. Secondly, the Brazilian Rainforest item was upsetting because the indigenous people were said to be slaughtered by the Europeans a few centuries ago.

What I've been told is the odor was added to natural gas after an explosion at the New London school in 1937.

As far as dogs are concerned they are mentioned in the Indian scriptures before any other civilisation began to form. As per science what you mentioned may be a good conclusion; science may not be the final word.

The smell of gas is made by added "mercaptans".

Humans made the Amazon rainforest? Gobsmacked

Chris Wallace-Smith

Volcanoes cause smog, dingos have been around more than 20-30 thousand years

gossmer, Humans evolved! Lots of evidence of evolution. Zero evidence of creation!

Very interesting!

RainingStars, manmade diamonds are not cubic zirconia. CZ are austrian crystal. Man made diamonds are the same as natural diamonds.

gossmer

Why do you insist on evolutionary thinking 🤔 there is no proof to millions of years and if it was we as humans would be gone due to cell mutations which have gotten worse since humans were created

Matthew McKechnie...Actually, Man helps the Oyster, to make Pearls, by placing a very small seed, or grain of sand, inside the Oyster. It bothers the Oyster, so it starts to secrete Nacre, around the seed/grain of Sand, that Man placed inside the Oyster, therefore forming a “Cultuted Pearl” that, yes, was made by Man...Manmade! Manmade Diamonds are known as Cubic Zirconia. They look like Diamonds, but really aren’t.
