An ecological crisis occurs when the environment of a species or a population changes in a way that destablizes its continued survival. There are many possible causes of such crises: In biology, a species is a kind of organism. ...
It may be that the environment quality degrades compared to the species' needs, after a change of abiotic ecological factor (for example, an increase of temperature, less significant rainfalls).
It may be that the environment becomes unfavourable for the survival of a species (or a population) due to an increase pressure of predation (for example overfishing).
Lastly, it may be that the situation becomes unfavourable to the quality of life of the species (or the population) due to raise in the number of individuals (overpopulation).
The evolutionary theory of punctuated equilibrium sees infrequent ecological crises as a potential driver of rapid evolution. Ecological factors which can affect dynamic change in a population or species in a given ecology or environment are usually divided into two groups: abiotic and biotic. ... Predation is an interaction between organisms (animals) in which one organism captures and feeds upon another called the prey. ... World population increase. ... This article is about biological evolution. ... Punctuated equilibrium, or punctuated equilibria, is a theory of evolution which states that changes such as speciation can occur relatively quickly, with long periods of little change—equilibria—in between. ...

Ecological culture helps to ensure the humane essence of humankind, which is changing its quality and improving not just its relation to nature, but also its social relations.
The ecological interpretation of this expression is that "the creation of the beauty saves the world" because it is very closely connected with goodness, the love of humans for the world, and affirmation of the harmony between personality and nature.
Technocratic and ecological culture are not just two different approaches to the task of developing relations between culture and society, they are two different ways of realizing these relations, two different kinds of reflection and self-awareness of culture.
