Biodiversity decline is brought up by a couple different factors, but there are three main categories that come to play. Habitat conservation is the problem …show more content…
This can happen purposefully like the conversion of land or it can happen by accident from the expansion of species accompanying upon occasional exchange and trade. When trade patterns extend all around the world and the volume of trade increases, the spread of species beyond their natural domains continues to threaten many of the species that are native. The issue of invasive species is mainly a problem of monitoring and control. There is a concern of needing to disburse resources to conduct an externality attendant to different casual activities, when the externality is both 1) accidental to an otherwise unrelated activity, and 2) mostly for the benefit states (Kontoleon, Pascual, Swanson, 2007). Therefore there is a public good and free rider facet to the problem with invasive species. According to Perrings the deciding factor of the invasive species problem concerns with the weakest link nature of the public good, that is the state attempting the minimum amount of management concludes the quality and extent of the externality. This in turns bring a question to the poorer countries, do they initiate a lesser environmental management and conclude the aspect and duration of the invasive problems? The answer is no, they do not but do support in poor countries that the monitoring and enforcement is important in resolving the problem (Perrings, 2007). This will become more of a problem when the invasive are more prevalent as international trade increases. Additionally, the choice of the appropriate instrument for the management of the problem: prevention or control (Finnoff et al., 2007). Control deals with using current information and resources to minimize the negative impacts of invasives. Preventions involve investments in assets most fitting to decreasing the problem over time. The choice between control and prevention depends more on the cost-effectiveness. It
