Why coconut trees are mostly found near water bodies?

coconut widly grows in coastal ares with content of salt. It can be seen all along west coast(kerala,karnataka,goa,maharashtra) and east Coast(TN,AP,Odessa,Bengal)..

inner peninsular areas also grow coconut like,Coimbatore,pollachi of TN. Pollachi has a special breed also.

But it does not grow in North. Have u seen any where in Delhi or UP ,a coconut tree ?

TN leads the country in coconut production,the status earlier served by Kerala.

Kerala is named after coconut tree ie., keram (in Sanskrit).THERE IS NO DISH/FOOD IN Kerala ,WHICH DOESN'T contain at least one/some part of keram,
