Why we should care about invasive alien species from a health perspective The anthropogenic movement of pathogens into new geographic locations or host species, so- called “pathogen pollution” [1], is one of the main threats to human and animal health in a globalized world. Human health can also be affected by viral bacterial pathogens and dinoflagellates that are transported in the ballast water of ships. A high proportion of those species identified also pose a threat to human health ranging from nuisance to disease transmission. Invasive species are a major threat to the livelihoods of the people who live in the areas they colonize. Ideal habitat varies for each species. For example, invasive plant pathogens such as emerald ash borer, which causes a massive devastation to ash trees in United States, the ash trees earlier acted as a sink to air pollutants ( Jones and McDermott, 2018 ). Invasive species can cause harm to the environment, economy, or human health and safety. Zoonotic diseases, invasive alien species and wildlife trade – is the current EU legislative framework fit for purpose? This review focuses on the ecological interactions that produce impacts associated with invasions by the most prominent group … Invasive species are any species that are non-native to a particular ecosystem and whose introduction and spread causes, or are likely to cause, socio-cultural, economic or environmental harm or harm to human health. Affect human health Reduce property values Economic costs: 50000 introduced species in US $137 billion estimate of annual economic and ecological cost of invasive species in US. Restoring islands through the removal of non-native invasive mammals is a powerful biodiversity conservation tool. Climate change, land use, and transport vectors interact in complex ways to determine the spread of native and non-native invasive species, pathogens, and their effects on ecosystem dynamics. IAS have adverse effects on national economies, food security, human health, as well as biodiversity and habitat. Several invasive species occur across neighbouring countries. Edited by Giuseppe Mazza and Elena Tricarico. For example, the shrub Parthenium hysterophorus is suspected to have accidentally been introduced to Ethiopia through relief food donations in the mid-1980s but has since spread to Kenya, Uganda, Tanzania, Somalia, and South Sudan, says Dr Staline Kibet, an expert in botany, range, and dryland management at University of Nairobi, Kenya. Examples of invasive species. Invasive species are transported to new environments via vectors and pathways. Invasive species are organisms (plants, animals, or microbes) that are not native to an environment, and once introduced, they establish, quickly reproduce and spread, and cause harm to the environment, economy, or human health. Some invasive non-native species can also affect human health. Economic costs of invasive plants and animals in the USA are estimated at $137 billion and in SE Asia at 33.5 billion per annum. Through disrupting ecosystems, invasive plants, insects and diseases impair many of the things humans need to sustain a good quality of life – including food and shelter, health, security and social interaction. Vectors are biological methods of transferring species such as an organism carrying a disease and transferring it directly to another—examples include mosquitoes, ticks, and even humans carrying the flu virus.. Some biotic invasive species affect the human health through environmental contamination (Kueffer, 2017, Jones and McDermott, 2018). Hardback. The impact of exotic invasive species on our forests in the U.S. is staggering. The 51 biodiversity and human health experts agreed on the top 100 invasive alien species that constituted at least a medium risk to biodiversity and of these 20 were ranked as very high risk.
