IUCN Determines the Human Being as a Factor in the Increase of Invasive Species
International, 10/6/2015

According to statements made by a specialist from the International Union for Conservation of Nature (IUCN) humans have contributed to the increase of invasive alien species in recent years, which has a high economic cost.

Genovesi Pietro, head of the invasive species specialist group of the organization, said in a speech at the headquarters of the UN Food and Agriculture Organization (FAO) that activities such as tourism or trade encourage the emergence of these harmful species to the ecosystem, whose number has multiplied by 76% in Europe, between 1970 and 2007.

Only in Europe is estimated to cause losses of 12,500 million euros per year, said Genovesi, who also revealed how many of these species adversely affect ecosystems and livelihoods of the people.

The recent opening of a new stretch of the Suez Canal in Egypt drew attention to the invasion for hundreds of species in the Mediterranean Sea, the increase of mosquitoes and the spread of diseases like malaria, the expansion of certain grasses in Africa and the spread of beavers in Tierra del Fuego, among other threats.

"Although the number of species locally hasn’t change, global biodiversity is being lost by such events”, said Genovesi, who noted that all regions of the world face this problem, including protected areas.

To prevent such effects, he requested extreme motion control of these species and the routes use to introduce them into new environments - naturally or intentionally - as well as raising awareness and developing codes of conduct for the pet trade, hunting, horticulture, botanical gardens and other activities that may pave the way for these living beings.
