Abstract

Human activity leads to environmental transformations, frequently on a large scale. There are places where anthropogenic consequences are unprecedented and disadvantageous to the extent that can be perceived in terms of an ecocatastrophe that goes beyond the local range. The article presents three anthropogenically degraded areas that pose danger for ecosystems in various parts of the world.

Abstract

Changes in the environment that are caused by the activity of beavers bring numerous advantages. They affect the increase in biodiversity, contribute to improving the condition of cleanliness of watercourses, improve local water relations and restore the natural landscape of river valleys.

Rapid increase in the European beaver population in Poland in 21st century determines and accelerates the process of renaturalization of the areas that have undergone partial degradation as a result of anthropopressure. A singular example is the river valleys populated by beavers that have been adapted to people’s needs in the last centuries, which has inevitably exerted an undesirable effect.
