A. new land for agriculture
B. rationing of the water supply
C. elimination of pests such as mosquitoes
D. more room for development of real estate

Option A,  new land for agriculture

Explanation:

Everglades system was carved by nature to hold water. It lies at the conflux point of two large drainage ridge a) western inland ridge and b) Eastern coastal ridge and hence comprises of a broad shallow valley sloping. The purpose of draining Everglades in Florida was to empty a swampland covering a huge area of 4,000 square miles  by digging canals in order to create farmland. The water for this farmland can be drawn by the plantation or it will be extracted and allowed to flow into the ocean.  

Hence, option A is correct

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
