What economic system do the Yanomamo follow? The Yanomamo are a South American Indian tribe living in spread out villages in the Amazon region of Brazil and Venezuela. The Yanomamo had no contact with outsiders until in the middle of the twentieth century. The Yanomamo grow plantains and bananas for much of their food. They supplement this with hunting and gathering palm fruit. They meet their basic needs without outside contributions or trade. The fathers teach their sons how to hunt, the mothers teach their daughters to cook.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
