Final answer:
Human activity increases disease transmission in wild populations through encroachment into wild habitats, the consumption of wildlife, changes in agriculture, and rapid urbanization. These factors contribute to the spread of diseases like monkeypox, malaria, HIV, and Ebola and also lead to a decline in biodiversity.
Step-by-step explanation:
True, human activity does increase disease transmission rates in wild populations. The increase in human populations leads to closer proximity, and as humans expand into new areas like wild habitats for residential development, mining, farming, or logging, they often come into contact with new pathogens. For example, the practice of consuming wild animals has led to the crossover of diseases like monkeypox, malaria, HIV, and Ebola from animals to humans. Moreover, the introduction of new crops attracts pests carrying new pathogens into farming communities, and rapid urbanization without adequate sanitation facilities promotes the spread of diseases in crowded cities.
Activities such as habitat loss, climate change, and increased pollution also contribute to a decline in biodiversity, potentially leading to greater opportunities for diseases to emerge and spread. Pathogens often require large, contiguous populations to sustain themselves, and the densification of human populations provides such an environment. Lastly, the disruption of ecosystems, such as through deforestation which may lead to alternative food sources for disease-carrying animals, can further facilitate the transmission of zoonotic diseases to humans.
