Advantages and disadvantages of New Guinea

I choose this headline because in New Guinea they don't have the environment to grow wheat and barley. The available food they can get is sago and taro. the problem is that sago takes a long time to turn into a kind of dough that they eat and its low on protein and taro rots quickly. Another disadvantage is that New Guinea does not have the animals that they can eat. The only protein they can eat are giant spiders. They don't have cows,sheep and goats like middle easterns do. The Natives of New Guinea have pigs. Which is good to eat but does not produce wool and fur. The advantages of New Guinea have productive crops and geographic luck.
