The invasive species is a non-native species (include plants and animals) invade a new area which outside its natural range by different ways to cause negative impacts for the native environment, economy, society and human health with the increasing number of its population. And the invasive species commonly have three main characteristics: rapid reproduction, short growth cycle and the strong ability to adapt different environment conditions and habit types. Those characteristics make the invasive species have the advantage in local competition for living space and food affect native species to survive. Then the population of invasive species will increase significantly which threaten the local biological diversity. Therefore it will destroy the suitable habits for the other species which depend on the local biological diversity and change the ecological system.
Moreover, the invasive species can also bring direct and indirect economic harm. First of all, the invasive plants and animals will become the harmful organisms to affect to the economic development of agroforestry. Furthermore, it will bring the indirect huge economic loss by negatively influencing the ecological system which includes a series of water and soil, and climate effects.
Bottom Line: We should pay more attention about the invasive species problem and all countries should work together to minimize the effects.
