Final answer:
The primary cause of species invasion and illegal trafficking is economic factors, linked to overharvesting, the introduction of exotic species through the pet trade, and habitat loss. Human-driven activities foster environments ripe for invasive species and create a high demand for illegal wildlife. Climate change, fueled by fossil fuel consumption, is also set to become a major factor in biodiversity loss.
Step-by-step explanation:
Cause of Invasion and Illegal Trafficking of Species
The cause of the invasion and illegal trafficking of species can be attributed primarily to economic factors. The illegal pet trade contributes to the risk of overharvesting and the introduction of exotic species, both of which are a direct result of human activities related to economic growth and consumer demands. Furthermore, human activities and the resulting habitat loss create an environment where invasive species can thrive, often at the expense of native species and biodiversity. This, in combination with other stresses such as habitat destruction and unsustainable resource use, leads to a decrease in biodiversity and can also fuel the demand for rare species, thus perpetuating the cycle of trafficking.
Additionally, climate change, propelled by the overuse of fossil fuels and excessive consumerism, is predicted to play an increasingly significant role in species extinction. Although not as widely recognized as habitat loss or the introduction of exotic species, pollution and human overpopulation also contribute to these environmental issues, exacerbating the problem of illegal species trafficking and invasions.
