There has been a sudden increase in the number of people becoming aware of invasive exotics. However, the awareness is not the result of educational campaigns regarding these exotics or political reviews or promises, but due to the negative impact that these species are leaving not only on the economy but also the society and ecology and environment.

Invasive species is a categorization used for flora and fauna, and for specific restoration-preservation processes in native habitats.

Such non-indigenous species, when introduced in an area or a country, have an adverse impact on the natural habitats, which they destroy in order to settle themselves.

According to European Union, these species imbalance the biological diversity. Such species are not always introduced in an environment; at times they are accidentally or naturally introduced.

The today's advancing technology and transportation has been a source of help for these species. As a result, several island-states, which had no threats due to these species, are now counted similarly vulnerable as land-locked states.

A control over such species has emerged as a major challenge across the world. It is being expected that if such species are not controlled, it could cost an economy approximately $350 billion a year. UK spends an estimated £1.7 billion yearly to restrain the impact of three freshwater species.
