human impact on biodiversity Flashcards
what is monoculture?
growing single crops over large areas, typically without crop rotation, directly decreasing the diversity of plants and of species that depend on them for food or a habitat. Monocultures also deplete the nutrients from soil.
explain how Converting woodland and hedgerows into fields is damaging to biodiversity ?
decreases numbers of trees and other species, and destroys habitats relied on by many species.
explain how Filling in ponds, draining marshes, over-grazing of land is damaging to biodiversity?
directly destroys habitats and reduces species diversity
how does removing weeds with herbicides damage biodiversity?
This may harm other species or those that depend on target species.
how does using pesticides to kill crop pests damage biodiversity?
This may harm other species or those that depend on target species.
how does using inorganic fertilisers damage biodiversity?
These may runoff into water courses, causing issues for aquatic species
how farmers balance conservaton and agriculture?
Maintaining hedgerows.
Reducing pesticide and herbicide use.
Using organic fertilisers.
Using crop rotation.
