Final answer:
Humans have transformed ecosystems by turning natural habitats into farmland and emitting greenhouse gases leading to climate change.
Step-by-step explanation:
Humans have altered the Tropical Forest and Conservation (TfC) environment/ecosystem in several ways during the past 100 years. Two notable methods include:
- Converting natural ecosystems such as prairies, wetlands, and forests into agricultural lands for farming, which impacts biodiversity and leads to habitat loss.
- Emission of greenhouse gases from activities like burning fossil fuels for industry and transportation, which is leading to global climate change and affecting ecosystems on a planetary scale.
These human-induced changes have reshaped the natural world and continue to pose challenges for the sustainability of ecosystems and the biodiversity within them.
