Many things around us that we automatically treat as something naturally made, that humans did not interfere with, but you will be shocked by the fact that you know that there are dozens of things that we automatically assume are natural that are not natural at all, but rather are the result of human interventions in them.
Amazon forests
When we talk about the Amazon rainforest, we refer to it as a natural, untouched tropical paradise, and we are all responsible for its destruction. The last part may be true because we do exactly that, but the natural part is wrong. Of the historical civilizations, which altered them on a large scale to adapt to their ways of living, as these civilizations completely changed the landscape with their own way of living, and this can be clearly seen in the plants indigenous to the Amazon forest region, where I found many modifications to the native plants, for example, the peach palm The original fruit weighed only about 1 gram, and now the type that exists today can weigh up to 200 grams. Previously, we thought it was a natural type of fruit, but scientists discovered that different tribes that lived in the Amazon, for centuries, crossbred the local plants. Along with some other plant species, and in general, recent studies have shown, humans have had a significant influence on the shape of the Amazon forest today.
pearls
There was a time when pearls were among the rarest and most expensive things we could get, only a few people could have them, and the high price is due first to their good looks, then to the risky way of getting them, of having to dive to the bottom of the ocean to fetch them, and though Although pearl jewelry and brooches are still very expensive, they are now easily accessible. So, what has changed? In short, humans figured out how to make them in a laboratory by replicating a natural process, by injecting gold and silver into mollusks, and replicating natural conditions in a laboratory, a process that was introduced and perfected by Japanese scientists in the early 19th century, and certainly a small minority still exist. They are working to pick up pearls from the ocean as in ancient times, however, the majority in the market are cultured pearls.
Lemon
If you don’t cook much, you probably won’t realize how important it is Lemon In our daily life, from marinating meat to adding a little flavor to most drinks summerLemon is considered a versatile fruit that happens to be loaded with vitamin C, and if we trace back its origins, we will realize that nature did not give us lemons in the first place because originally it was not a natural crop, but the ancients created the yellow fruit that we see today, it is generally agreed that lemons first appeared Once in the foothills of the lower Himalayas in Burma, about 2000 years ago, by crossing the citron plant with the lime plant, lemon trees are usually grown, by grafting seedlings of other citrus fruits, such as oranges, tangerines.
