What is an invasive species and why are they a problem?

An invasive species is an introduced non-native organism (disease, parasite, plant or animal) that begins to expand or expand its scope from its original introduction and can be environmental, economic or human.

Some well-known examples include unintentional introduction of West Nile virus, chestnut blight, South American ants, zebra shellfish, Burmese psittac and piper. In addition to deliberate introduction of Shinshi (T Yu), scum, sparrow, ostrich, and kipe

More than 6,500 of these harmful exotic species bring over 100 billion dollars each year to the US economy. Cost effects include crop losses, water facilities and waterway obstructions, wildlife and human disease transmission, fisheries threats, increased fire vulnerability, adverse effects of ranchers and farmers

Invasive species are a major problem globally. Non-native species that are defined to live outside the range of native species can cause harm or harm, and invading species destroy natural habitats, harm the regional economy and human health Can be threatened. Intruders have damaged billions of dollars annually and about 42% of the species that are classified as endangered species in the United States are primarily at risk of invasion. Including our ocean - invasive species can be found in almost all ecosystems of the world

Invasive species are a major threat to many native habitats and species in the United States and cause serious damage to agriculture, forestry and recreation. The term "invasive species" may refer to an introduced or naturalized species, wild type or introduced disease. Many species are invasive. Several species such as dandelions are not conventional, but do not cause significant economic or ecological damage and are not widely considered invasive. Overall, it is estimated that 50,000 unconventional species, including livestock, crops, pets and other noninvasive species, were introduced in the United States. Economic losses associated with invasive species influences and management costs are estimated at $ 120 billion per year

Every year, billions of dollars and millions of hours are spent to treat invading species around the world. By definition, an invasive species is a non-native species that causes damage related to economic, environmental and / or human health. The invasive species may be a pathogen such as a plant, an animal, and / or West Nile virus. These species usually grow rapidly and propagate and often lack predators and pathogens in the environment in which they are introduced and erupt their population. Historically invasive species such as chestnut blight and smallpox are now shaping our landscape while other species are just beginning to affect our environment. Invasive species management can be expensive and time-consuming. However, proper education of invasive species can prevent intrusion at first. Strong education and outreach activities increase people's awareness and promote prevention
