    Many PFAS such as PFOS and PFOA pose health and environmental concerns because they are persistent organic pollutants; they were branded as "forever chemicals" in an article in The Washington Post in 2018. [10] Some have half-lives of over eight years due to a carbon-fluorine bond, one of the strongest in organic chemistry.

    The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage. [8]
