The problem on the sewage pollution of coral reefs has been present for quite some time. In fact, the current regulations allow public treatment so that there can be a modification of the pollutant discharge. Coral reefs are seen as "distinctive habitats of limited distribution." It is critical that they are protected because of their importance to man. This paper looks at the ecological impact of the different discharges of coral reefs. There are three major components of sewage control and this includes eutrophication which is related to the high nutrient concentration which is released in the waste waters; the sedimentation of suspended solids and its toxic effects. (Ecological Impacts of Sewage Discharges on Coral Reef Communities). Different other factors are hazards to coral reefs such as climate change and overfishing, but pollution that arises from untreated sewage is a more serious danger to reefs.

Gating is an effort to control access to the settlement, especially to unwanted social contact. Gating usually manifested on spatial elements such as gate, wall, fence, security check point, swing up portal, etc. at their main entrance. The term gating then relates to gated community as a modern-exclusive residential which is in some cases, reinforce both spatial and social segregation. This paper analyzes gating and its relation to segregation from spatial point of view. The role and function of wall, gate, and border is analyzed to define whether it is a manifestation of security or a matter of life style. This paper concludes gating as both security and life style aspect, and gives influence to semi-restricted segregation.
