Why do we cover our smell?
Perfumes began to be used in the 1700s, especially in France, where the streets stank, and it turned into the most profitable industry because we don't want to smell like humans.
We prefer to smell flowers or trees.
A perfume always has a prominent note and subnotes that are almost subconscious like excrement or human urine, which in tiny amounts we find pleasant even if we don't think so; we also use anal glands from certain animals.
How curious
Animals use certain scents to protect themselves from parasites. Birds, for example, put scents in their nests.
We have huge noses.
If you compare the inside of a human nose to that of a dog or rabbit, ours is small. Inside our nose we have 350 receptors to detect different odorous molecules, but a mouse has 1,200, and an elephant, 2,400. Smelling we are not the best.
A dog that sniffs its neighborhood has everything under control.
They see history, they can see what happened there, they can smell the trail of an animal days after it has passed by and they can smell what is coming before they see it.

A plant emits molecules in its neighborhood to warn of a danger and the other plants vary their scent to avoid that predator.
How ready!
Imagine a loose cotton plant that can be attacked by different insects; the plant will change its chemistry according to which insect is eating the leaves because it distinguishes the saliva of each one and will cause an effect calling on the enemies of that particular insect to rid it of the pest.
Fish also have a sense of smell.
And excellent. Salmon find their way back home, from the ocean to the place in the river where they were born, through smell. All fish have different types of pheromones to communicate.
And the birds?
They also communicate through smells, but they go further; the albatross, for example, is able to smell plankton at very long distances: it knows that if there is plankton there are many fish.

They can be trained to detect virtually any scent such as dogs and rats; there was a rat who got a medal for detecting 70 mines in cambodia.
What is the smell of the future?
I am carrying out a large research project and we see that the gases we emit are very polluting and change the smell of things, so that insects cannot find the flowers they need to pollinate.
Is species communication in danger?
Yes, and their pheromones are rusty and they copulate with the wrong species. We will see constant and negative changes. We are stupid, instead of curbing CO2 emissions we increase them. I am convinced that we are headed for extinction, but the Earth will be reborn without us.
