Excretion is one of the major ways the body maintain homeostasis. what role does the kidney play in maintaining homeostasis

Hi!

The kidneys help maintain homeostasis by regulating the concentration and volume of body fluids. 

Humans change ecosystems in many ways, such as habitat destruction, pollution, introduction of invasive species, and overexploitation of species. The most common way that humans damage ecosystems is by destroying habitat. For example, we remove trees, change the flow of water, and change grasslands into farms.
