Final answer:
In tropical wet climate zones, agriculture is the main economic activity, benefiting from high net primary productivity and conditions suitable for a variety of crops. Additionally, tourism is a key industry, especially in the Caribbean. Traditional farming methods are common, and there is a focus on conserving the rich biodiversity.
Step-by-step explanation:
The economical activity in the tropical wet climate zone is primarily driven by agriculture, given the warm temperatures and abundant rainfall conducive to plant growth. This allows for high net primary productivity and the ability to support a variety of crops. Historical examples include plantation agriculture in the north and east coast of South America and the Caribbean, initially relying on forced labor, which has led to a high percentage of people of African or Asian descent in the region. Presently, nations such as Indonesia heavily depend on agriculture for their economy and employment, with key exports including spices, coffee, tea, palm oil, and rubber.
Tourism also plays a significant role in tropical wet climate zones, especially in the Caribbean where the pleasant climate and beautiful landscapes attract visitors worldwide. The stable temperatures and lack of pronounced seasonality in the tropics support biodiverse tropical wet forests, comprising various plant and animal species, making these zones attractive for eco-tourism and biological research.
However, agriculture in these regions may often employ traditional methods, such as the use of water buffalo or oxen for tilling the land. The elevated biodiversity also poses challenges for agricultural expansion, as there are concerns about environmental conservation and the sustainability of economies based too heavily on agriculture or tourism.
