What I want to convey through this article is the importance of thinking rationally.
In today’s science-driven world, most thinking is centered around “logic.”
However, in reality, this way of thinking often doesn’t lead to successful outcomes in life.
You might ask, “Based on what?” — but all you need to do is look at the current state of the world or human history.
In this article, I won’t be explaining the question “Why do living beings eat other living beings?” with logical evidence.
Instead, I’ll approach it from a rational perspective.
I’d love to hear your thoughts on this. Criticism is welcome, too.
We cannot live without consuming energy.
This is a fundamental law of the universe.
Everything that exists — organic or inorganic — requires energy in order to exist.
Even inorganic matter needs energy to be created, and even to use inorganic materials, energy is essential.
We humans, like most living creatures, consume energy through food.
What we eat — whether plants or animals — is always another form of life.
So why is it that living beings consume other living beings?
Why do we need a hierarchical structure like the ecosystem?
Let’s explore these questions through a rational lens.
The universe, the Earth, and even the human body — all are governed by balance.
All things coexist by maintaining this delicate equilibrium.
Which means: every being, every element, has a role to play.
The human body is probably the easiest analogy.
Each organ has its role, and that’s why we’re able to live.
We stay alive because these specialized parts are maintaining balance together.
With that in mind, the answer to why living beings consume each other becomes clearer.
The current form of Earth exists because that balance is maintained.
Which means: humans, plants, animals — all are necessary, and each has its own purpose.
But what would happen if any one element became too numerous, or too scarce?
What if all animals could survive without preying on one another?
What would happen to the balance of the planet?
We may think of ourselves as individuals, but in reality, we are simply one component of Earth’s system.
Like a single cell in the human body.
Our brief, fragile lives may feel significant to us, but from the planet’s perspective, we are just one small part of its structure.
So roles are assigned, and balance is maintained by mutual adjustment.
The same can be said about lifespan.
In human terms, it’s like the natural cycle of cells being replaced over time.
And from that same viewpoint, we begin to understand the question:
Why do we gain weight?
We’ve seen that living beings consume others both to survive and to help balance the system.
So then, why do we gain weight?
The answer is: this too is for balance adjustment.
When a single organism consumes excessively, the balance is disrupted.
To prevent this, the organism’s predation capacity must be reduced.
So it gains weight — slowing down its movement and reducing its consumption.
This is an answer you would never reach through logical thinking alone.
It’s not about “What mechanism causes weight gain?”
From a rational perspective, the question becomes:
“Why is it necessary to gain weight?”
In today’s world, humans can consume whatever they want, whenever they want — as long as they have money.
This significantly distorts the Earth’s balance.
And it’s not just about ecosystems.
For example, why does an increase in inorganic material lead to environmental destruction?
We can answer this with the same line of reasoning.
Earth has a limited capacity.
When inorganic matter is introduced — something that didn’t originally exist — it can only be balanced by reducing existing organic matter.
It’s not that causes lead to effects.
Rather, effects occur because they are structurally required.
This is a critically important distinction.
For centuries, humans have been tightening their own noose.
Is there really anything good that comes from things becoming even more convenient?
Is there anything more valuable than everyone on Earth being able to:
Eat every day,
Spend time with their loved ones,
And sleep safely at night?
What do you think?
I’d truly love to hear your perspective.
Why Do Living Beings Eat Other Living Beings? Why Do We Gain Weight?
