Erosion of biodiversity through cultivation

Nature 
Species diversity increases initially in response to cultivation but then losses increase as intensity of management rises. Such losses may also affect food security through increasing vulnerability to diseases, competition from invasive species and economic opportunities through a narrower range of production choices.
Claim 
1. It is clear that intensive agricultural systems have changed the genetic diversity of crops and livestock and are also having a major influence on wild species and unspoiled natural habitats.
