Ecology paper - Essay Example The focus of study in the article was to understand how invasive species, pathogens and disease vector affect human health and determine appropriate measures to reduce disease emergence. The study depicts that invasive species and infectious diseases have become prevalent and widespread because of the increased connectivity in human population. The connectivity in the current world has attributed to the disease outbreak. The new developed trade routes in the previously disconnected countries increase human interactions. Crowl et al., (2008) demonstrated that the enhanced transport systems such as airplanes have increased spread of pathogens. The invasive species has become the second contributing aspect to extinction and endangerment of species in the United States after the increased human population and related activities. The United States government spends almost 120 billion dollars to cater for the non-native species in the country (Crowl et al., 2008). The evidence used to support contrasting point of view was the explanation of the spread of the avian-dispersed H5N1 avian influenza disease worldwide. In-depth and integrated network of research platform was es sential in full understanding of the spread and impacts of the invasion species. The point of view that I most agreed with was the fact that modern technology such as airplanes contributes to the increasing spread of pathogens and invasive species. Most disease in the world emerges from a single area and spread to the entire world. The point became convincing because of the evidence given involving the spread of avian-dispersed H5N1 avian influenza disease. Other points of view in the article such as cause of non-native species extinction became less convincing because of lack of material evidence. Crowl, T. A., Crist T.O, Parmenter, R. R., Belovsky, G., & Lugo, A. E. (2008). The spread of invasive species and infectious disease as drivers of ecosystem change.
