That statement is incorrect. Humans have a profound impact on the environment, and that impact almost always disrupts the balance of ecosystems. Here's why:

* Habitat Destruction: We clear forests, drain wetlands, and build cities, destroying habitats that countless species rely on.

* Pollution: We release pollutants into the air, water, and soil, poisoning ecosystems and harming organisms.

* Climate Change: Our emissions of greenhouse gases are altering the climate, disrupting natural patterns and causing shifts in ecosystems.

* Introduction of Invasive Species: We accidentally or intentionally introduce species to new areas, which can outcompete native species and disrupt food webs.

* Overexploitation: We harvest resources, like fish or trees, faster than they can replenish, leading to population declines and ecosystem imbalance.

Ecosystem balance is delicate and easily disrupted by human activities. Even small changes can have cascading effects that ripple through the entire system.

It's important to recognize the human impact and strive for sustainable practices that minimize our negative influence on ecosystems.
