Impact Of Agriculture Flashcards
Why is biodiversity important?
Biodiversity boosts ecosystem productivity
Healthy ecosystems can better
withstand and recover from a variety of
disasters.
What is the problem with a large crop yield?
Any one area can only support a certain amount of biomass – if most of this area is taken up by a crop, then there is little area left for anything else
What is the problem with hedgerows?
Destruction of hedgerows, reduces species diversity
Whats the problem with monoculture?
increases disease and leaves few niches
Whats the problem with overgrazing?
prevents regeneration of woodland
Whats the problem with filling ponds?
Removes habitats
What is the impact of deforestation?
• Forests contain many varied and different habitats = high species diversity
• Permanent clearing of the forest leads to loss of habitats and in turn loss of biodiversity
• Loss of forests equal more CO2 environment changes reducing species diversity (potentially globally)
• Loss of root soil stricture leads to desertification
What is monoculture?
the production of a single species of plant
