Within nature, as you put it, there are native and invasive species.

Species implies "specified" aka separated from one another aka nature separating each being within from one another, which makes each being a native within nature and a foreigner to one another.

A species cannot invade...only invite one another.

they contribute to the balance.

Con-tribute implies "together in tribes"...being within nature implies each ones choice within all balance, hence separated from one another.

Notice that the tribe in charge implies each "chosen one"...

The introduction of an invasive species

Inception implies the introduction of each "specific" being within nature. A being cannot introduce...only invite one another further in, hence invasion by invitation.

The origin of artificial introduction is called creationism aka creatio ex nihilo (something out of nothing). That's how the invaders use suggestion to tempt ones consent to give invitation.

cannot adapt quickly enough

If nature moves each living being from inception towards death, then quickening shortens life. What's the difference between adapting to nature (perception) and adapting to one another (suggestion)?

to the new

What if there cannot be anything new within nature...only the same for each difference within?

Could differences distract each other with likeness? Could a suggested "new" distract one from perceivable "now"?

millennia of carefully balanced

Millennia implies the taking of measurement by a being within nature aka taking and holding onto what is given in motion. That ain't balance, but ones choice imbalancing itself.

balanced symbiotic

Balance can only exist within motion...motion generates balance (momentum) to establish choice (matter). That's an analytical process...not a synthetic symbiosis.

In simpler...balance implies choice in-between sides. Symbiotic implies choice holding onto a side, which turns both sides together.

Others suggest symbolism to tempt ones consent into a symbiosis aka mass consensus.

feeding

What if nature (inception towards death) feeds upon being (life)? Why is it that no matter how much one eats...hunger returns? What if eating and drinking implies each beings adaptation to natures hunger and thirst? What if nature is self sustaining and thereby generates each being to sustain self like energy (internal/inherent power) does?

Given time the environment also collapses due to the uncontrolled feeding frenzy

If nature gives "time", then time controls any being within nature? What if few tempt many to take time, which in return ignores given?

repeats the process

What if process implies ongoing for each temporal potential within? What if only a potential within a process can experience repetition?

legal or illegal

What if legal implies natural law, and illegal each being within natural law?

What if few tempt many to turn against each other by choosing to hold onto a side aka legal versus illegal...could that turn one from natural law, and towards the artificial laws few shape to govern many?

purposeful destruction of our way of life

What if the only way (inception towards death) of life implies destruction aka division (de) of structure (struct) within action (ion)?

What if few suggest purpose to tempt many to ignore perceivable origin for suggested outcomes?

What if life given to an off-spring implies by; within and in response to the process of dying? What if inception sentences life towards point of death? What if living implies a death sentence?

What if destruction implies analysis (reality), while construction implies synthesis (fiction)?
