High intertidal zone has rockpools and go to several months without being replenished from the seawater (McAllen & Taylor‚ 2001). Intertidal rockpool have a relative stable environment where that has few changes in terms of physical conditions when the water reaches low tide (Kemp‚ 2009).

1. Introduction Moral reasoning is defined as “individual or collective practical reasoning about what‚ morally‚ one ought to do”. The theory introduces two moral principles: consequentialist principle‚ which determines an act’s morality by its consequences‚ and categorical principle‚ which assesses an act by looking at its certain duties and rights despite the outcomes. To some extent‚ these two principles seem to contradict each other‚ which may become obstacles for achieving reasonable actions

drinkable. According to Arrandale (2002)‚ this method has been used by 130 nations which produces 6 billion gallons usable water per day. Another report (2010) states that some Middle East countries grow organic asparagus - a plant which can desalinate seawater. However‚ desalination costs lots of money due to high technology and not suitable for many countries which is not near the coastline. Furthermore‚ desalination would produces a super-saline water which cannot be eliminated back to the ocean.

For example‚ when one reads about the "bubbles of seawater coursing under" Carl’s shirt‚ and his "icy but brilliant pink" skin that looked as if the sea had parboiled in the sea‚ they might be disgusted. The imagery lets readers actually imagine a dead Carl in their mind‚ which can be very depressing. Death

It is a regular sight to see burning mangroves‚" informs Milli Shetty of Vikas Samiti‚ a resident of Kandivali who has been involved in saving the local mangroves. Garbage too is dumped into these intertidal areas‚ upsetting the salinity of the seawater and choking off mangrove tree roots. The dumping is a technique to illegally reclaim the land‚ and subsequently build on it once the trees have been destroyed. "As a result‚ people tend to associate mangroves with filth and smell‚" adds Milli.

Coastal Processes Coasts are shaped by the sea and the action of waves. Waves act in different ways‚ through the processes of erosion‚ transportation and deposition. Coasts: A coast is found where the land meets the sea. Coasts undergo change due to coastal processes and (as with rivers) there are main processes at work: Erosion Transportation Deposition Each of these processes involves the power of the sea and the effect of waves that are carried to shore. However other factors also
