The ecological impact of increased atmospheric CO2 on plant growth is significant, as it can enhance photosynthesis and growth rates in some species. While elevated CO2 may initially boost crop yields, it can also lead to altered nutrient content, making plants less nutritious. Additionally, changes in plant community dynamics can occur, impacting biodiversity and ecosystem stability. Some species may outcompete others, resulting in shifts in community composition that affect soil health and habitat quality. Understanding these effects is crucial for managing ecosystems in a changing climate.
