7.3.6: Maintaining biodiversity
Not started yet — this one needs some love.
Positive and negative human interactions in an ecosystem can affect biodiversity.
Scientists and concerned citizens have put in place programmes to reduce the negative effects of humans on ecosystems and biodiversity.
Breeding programmes can be used for endangered species.
Protection and regeneration can be used for rare habitats.
Field margins and hedgerows can be reintroduced in agricultural areas where farmers grow only one type of crop.
Some governments reduce deforestation and carbon dioxide emissions.
Resources can be recycled rather than dumped in landfill.
Biodiversity decisions may involve conflicting pressures, such as food production, land use, cost and habitat protection.
Common exam mistakes
Do not just name a conservation method; link it to how it helps species survive, breed or keep habitats.
Field margins and hedgerows are farmland examples, so use them when the question is about agriculture.
Protection prevents further damage; regeneration is about restoring a damaged habitat.
Conflicting pressures can include cost, food production, land use, jobs and conservation.
