How many animals are born around the world every day?

Birds also give birth to babies, so do bees, even small fleas do it. Maybe they don't have love but they are all fertile, so how many animals are estimated to be born in the world every day?

It is a question of an audience of the BBC's "More or Less" program, a program aimed at finding meaning from numbers that reflect our lives.

First, we need to look at what the term "animal" means? According to the Oxford English Dictionary defines an animal as "a living organism, eating organic substances, often with specialized sensory organs and nervous system and can respond quickly to stimuli." .

So "animals" will include mammals, vertebrates and invertebrates, animals that lay eggs and give birth.

To make it easier for you to imagine the scale of the question and the real answer to it, let's start with a notorious creature of fertility: rabbits.

According to estimates by Wildlife Britain, the number of wild rabbits in the UK is currently around 40 million. A normal rabbit will give about 7 litters in a year, each time it usually produces 3-7 baby rabbits.

If every wild rabbit in the country has 7 parities and an average of 5 baby rabbits on each litter, there will be about 1,917,808 baby rabbits born every day.

But sad or lucky truth (for us) depends on our thoughts! The high mortality rate in young rabbits leads to the majority of rabbits not reaching adulthood. Obviously this is a rough calculation and the real number will be much different.

What about the less common species like Humbold penguin ? This creature originated from the coastal regions of Chile and Peru.

Humboldt penguins often lay eggs in the nest and hatch eggs for hatching, usually they will lay two eggs at a time and a pair of Humboldt penguins can produce two hatchets per year.

While not all the eggs they produce are hatched, if we look at the numbers we get from studying these penguins in captivity and think that the same percentage is Wild populations, an estimated 14,400 Humboldt penguins hatch each year. So on average, about 40 Humboldt penguins are born worldwide every day.

The relatively small number of Humboldt penguins is a threatened species, classified by the International Union for Conservation of Nature (IUCN), a recognized global agency for related issues. to protect nature and "vulnerable" species .

When you compare it to a species that is not threatened - talk about a chicken - the numbers will be very different.

By extrapolating the data source collected by the United Nations Food and Agriculture Organization (FAO), we can estimate there are more than 62 million chickens born worldwide.

The number of chickens really is very much. And now we cross the bees.

It is estimated that in the warmer months of the year, honey bees average about 1,500 eggs a day. In January 2018, the number of bees that the National Bee Unit (NBU, which implements bee health programs in England and Wales), measured a total of 247,461 beehives in the UK.

So in the summer, in theory and in favorable and lucky conditions, there will be 371,191,500 honey bee breeds born every day.

Seems like these numbers are not correct? According to Monika Bohm, a professor and scientist at the Institute of Zoology in London (UK), that the whole number of a species in the world is an impossible task. because we do not know fully about the reproductive habits of species.

However, Professor Axel Rossberg from Queen Mary University (United Kingdom), believes that he may have the answer.

He said that species weighing only one-thousandth compared to other species often have a number of times more abundant. That means more bees than elephants, more termites than porcupines and ants than anteater.

One of the richest animals on this planet is the roundworm. There are about three million round worms per square meter of earth on earth. One of the extensively studied nematode species is Caenorhabditis Elegans or "C Elegans" - this nematode species is free, transparent, about 1mm long living in temperate soil environment. They lay about five eggs per hour.

The nematode individuals are very small but their populations are very large.(Photo: Science Photo Library).

By looking at the established ratios that allow populations to remain in a stable state, Professor Rossberg estimates that only 1 out of every 100 eggs will hatch, giving us a total of 6 x 10 powers. 20 individuals "C elegans" are born every day. An extremely terrible number.

The problem here is: 3 million round worms per square meter of land and 1 roundworm will produce 5 eggs per hour, 24 hours a day and hatching rate is 1%. When multiplied by the number of square meters of land on the whole earth - that is, about 150,000,000 square meters - will produce about 6 x 10 powers of 20 individual roundworms born every day on the entire land (as mentioned on). While the rest of the nematode population lives in the water - rivers and oceans currently occupy an extremely large area, if we calculate this number will be much larger than the calculated number there.

And that's just an animal, because we have so many: 40 Humboldt penguins, 62 million chickens, more than 1.9 million wild rabbits and even 371,191,500 individual honey bees. There are about 7.7 million animals already known on our planet and according to the US National Oceanographic and Atmospheric Administration (NOAA), there is an estimated 95% of the area in the oceans and 99% of the area. The ocean floor is currently undiscovered.

So until we study all the species on Earth, this question will not find a way out yet.
