Question

positive feedback loops tend to move a system further from its original conditions whereas negative feedback loops help the system maintain balance. climate change can cause hotter and wetter weather. this weather is perfect for insects, who are known vectors of several diseases. this means that the prevalence of insect - borne diseases will increase as the planet continues to warm and precipitation increases. what type of loop is this?
negative feedback
positive feedback

Explanation:

Positive feedback loops reinforce a system's direction (e.g., climate change → warmer/wetter weather → more insects → more insect - borne diseases → further climate impacts? Wait, in this case, climate change (warming/precipitation) leads to better insect conditions, leading to more insect - borne diseases. The initial change (climate warming) is amplified as the process leads to more of the related outcome (more disease, and the climate change process here is being reinforced? Wait, the key is: positive feedback loops enhance the initial change. Here, climate change (warmer/wetter) causes more insects (which spread disease), and this leads to a situation where the initial change (climate warming) is reinforced? Wait, the description says positive feedback loops tend to move a system further from its original conditions. Let's analyze:

1. Initial change: Climate change (warmer, wetter).
2. Effect: Better for insects (vectors of disease).
3. Result: More insect - borne diseases.
4. How does this relate to the feedback loop? The initial change (climate warming) is leading to a process that amplifies the impact (more disease, and potentially further climate - related changes? Or the system (climate - disease - insect) is moving further from its original state (less disease, less insect proliferation) because the warming leads to more insects, more disease, which is a reinforcement of the initial change's direction. Negative feedback loops help the system maintain balance, which is not the case here. So this is a positive feedback loop.

Answer:

Positive feedback
