Excerto: «As the climate warms, the number of alien species on every continent is expected to increase 36 percent by 2050. Some alien species—that is, plants or animals that live outside their natural range—are invasive and can harm ecosystems and the areas they invade with serious impacts on the global food supply, medicines, water quality, biodiversity, and livelihoods.
Rising temperatures, increased CO2, and extreme weather that alters landscapes favor the spread of invasive species, which also exacerbate climate impacts by making habitats, agriculture and cities less resilient. For example, when invasive plants overrun native plants and establish a monoculture, the area may be more susceptible to wildfires or pests. This phenomenon may intensify the effects of climate change on humans and our environment.
What are invasive plants?
Not all alien or non-native plant species are invasive. Invasive plants are defined as those that adapt easily to new environments, reproduce quickly, and damage the native species, ecosystems, property or economy of their new terrain. Many food crops, such as wheat, rice, tomatoes, and garden plants are non-native and are not considered invasive. (...)».
