kepsov in 1972, who believes that ecology, and interactions that affect population size are studied.s is where there are no people no animals, where only nature there is no ecology, but in fact where there is no struggle for existence. there is no ecology where there is no competition for existence, where they ate against birch trees. in any case, this one here, we can find 150 more definitions of ecology there. but it seems to me, now, uh, what we are going to discuss today and how the tasks are set. it is rather human ecology, because more and more science is being transformed and is studying those environments that affect humans. it's a biological environment - it's like what we are we mean by the natural environment there. this is, uh, our social environment and, uh, our environment, which is associated with a man-made impact, that is, a person who affects the world around us. and i think that running there is something to say on this topic, but it seems to me, uh , that's it, more than this factor is the circle that we mean by the social environment. he's turning more and more.
