The article Wild Boars will inherit the Earth by Adrianne Jeffries discusses the global population explosion of wild boars and the devastating effects this animal have on local environments. In the US is projected that the wild boar population causes around $1 billion in damages from destroying crops, local terrain and spreading disease. The spread of the wild boar can be seen as the spread of a disease, in terms of studying the network of the population growth and its effects.
A disease, if it is strong enough and persistent enough, which spreads through a population, can have devastating effects by possibly limiting the supply of labor in the economy, diminished aggregate demand, and possibly lowering the output of the economy and an invasive species like the wild boar can have the same effects on the economy. An invasive species like the wild boar can have much of the same effects, especially so if the diseases it can spread end up infecting enough people, by destroying crops, diverting funds to hunting them, and negatively effecting the ecosystem. This animal’s spread can be seen as spreading from state to state/area to area, much like a disease spreads from person to person. An area can become “infected” from an animal if, for example, the animal eats the crops grown in the area, or if the climate that time of year is the type the animal lives in, and this animal can be spread to other areas as the weather changes or as farmers grow different crops. The animal settles into the area increasing the risk of surrounding areas to become “infected” as the animal population grows and seeks other areas to expand.
The movements of an invading animal species can be seen as a disease that infects areas that present ideal conditions for the animal to live in and this can be mapped on a graph to then better predict where the animal may spread and what preventative measures can be taken to help stem the threat of the animal. Right now, the wild boar is a hard animal to hunt and may be an invasive animal that will be hard to get rid of.
