Here's why:
* Ecology is the branch of biology that focuses on the interactions between organisms and their environment. Deforestation directly impacts the environment and the organisms that live within the rainforest ecosystem.
* Other relevant fields:
* Conservation Biology: This field focuses on protecting species and ecosystems, making it highly relevant to the study of deforestation.
* Forestry: Forestry professionals often study the effects of deforestation and sustainable forest management practices.
* Climate Science: Deforestation has significant impacts on climate change, so a climate scientist might also be involved in studying the influence of deforestation.
While other fields like botany, zoology, or soil science might have relevance, the core focus of a scientist studying the *influence* of deforestation would lie within ecology.
