How does the ability to use domesticated plants and animals differentiate the Polynesian societies?

How a society utilizes domesticated plants and animals greatly affects their culture. Each Polynesian island has a distinct culture and society. Polynesia is typically divided, culturally, into east and west. West Polynesia has a higher population and strong traditions in trade, justice, and marriage. East Polynesia, on the other hand, is comprised of cultures that are adapted to smaller islands and smaller populations.
Regardless of population and available land, all Polynesian societies depended on farming, fishing, and sailing in order to produce resources and conduct trade. However, even with farms and domesticated animals, many islands were subject to periodic famines and droughts, making the navigation of the seas an important skill.
Polynesian settlements consisted of either a village or a hamlet, depending on the size of the island. This, too, affected agriculture amongst Polynesian societies, as productive farms require abundant space and fertile soil. Hamlets were seen on the large volcanic islands and were placed further inland, because resources were plentyful. It was the hamlets on the larger islands that had a productive agricultural system. Villages peppered the coasts of the smaller islands, where resources were less available and the societies depended more on fishing and trade.

From their earliest settlement, the agricultural potential of Polynesian islands was made use of by Pacific Islanders. The different environmental factors of various islands meant that local populations had to adapt their agricultural techniques to best suit their location. Some parts of Polynesia receive a lot of rainfall, and Polynesians took advantage of highly nutritious yet thirsty crops, such as plantains. Other islands that receive less rainfall supported more drought-tolerant crops such as taro. Soil type also played a huge part in the differentiation of agriculture in Polynesia. Large volcanic islands tend to have rich and fertile soil that can support large-scale, sustained agriculture over generations. Smaller coral atolls lack nutrient-rich soil. Therefore, the people there tended to only use limited agriculture to supplement a mostly seafood-based diet.
One thing that unites the Polynesian diet is pork. From the very beginning, Polynesians brought pigs with them when they settled their islands. The inclusion of pork in Polynesian diets provided a reliable source of protein.
