I remember the time when I got accepted at Department of Environmental Engineering, ITS, I was very happy as being a part of environmental engineer family was my expectation. But of course I had to work hard to pass the exam to go to that college, which was called UMPTN, similar with SAT test in US.
Almost all aspects involving alteration of natural environment now require that the impact, interactions and effects of every designed structures towards natural habitat or ecosystems be considered and assessed for any kind of activities. In US, this was in 1970 which the principle was enacted into federal law.
