weeeeeb [17]

He needs to be careful to document his sources about the problem of invasive species.

<h3>What is Invasive species?</h3>
  • An introduced organism that overpopulates and damages its new environment is referred to as an invasive species.
  • Even though the majority of introduced species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.
  • Invasive species are one of the largest issues our natural environments have ever faced.
  • Invasive species have the potential to proliferate rapidly in the absence of their natural predators, displacing native species, destroying ecosystems, and incurring high costs.
  • This increase is frequently attributed to growing global trade, manufacturing specialization, and linkages to previously remote areas.
  • Additionally, the extension of existing imported specie's ranges is made possible by climate change.
