B-he describes it as pilgrims at a shrine
Alan Weisman on his book "The world without us" provides us an overview on how we - humans - are having a highly negative effect on nature. At the beginning of chapter 1 he contrasts the power of humans to that of the nature making reference to an old forest located between Poland and Belarus which is more vulnerable day after day. This reality has increased since the democracy and independance instauration which makes us infer that the more advances we have in society, the less care human pay to nature.
I believe that the answer for this would be DESTRUCTIVE. The stream at the Karnala Bird Sanctuary, India is considered as destructive because it causes stream erosion. Both constructive and destructive processes are considered as part of the changes that occurs in the planet all the time. Hope this answers your question. Have a great day!
