Student A:Human impact on the environment has resulted in an increase in the intrabreeding between species, with introduced species worldwide, which has resulted in an increase in hybridization. The genetic mixing may threaten many species with extinction, while genetic erosion in crop plants may be damaging the gene pools of many species for future breeding.
