Answer 25

More chemicals in the food chain (accumulation)

Question 26

What is the solution to the inorganic pollution boundary?

Answer 26

DDT banned

Question 27

What has the increase in agriculture caused?

Answer 27

Hedge removal = decrease biodiversity Monoculture (grow one crop) = less habitats, minerals from same depth of soil taken, more fertilisers, etc Overgrazing = reduced water drainage

Question 28

What is deforestation used for?

Answer 28

Timber Farming Roads

Question 29

What are the consequences of deforestation?

Answer 29

Soil erosion, flooding, cold soil which attracts denitrifying bacteria, less rainfall, habitat destruction, more Co2

Question 30

Give advantages and disadvantages of fish farming?

Answer 30

Reduced carbon footprint, raising fish better the pork, overcrowding causes disease to spread, pollution of pesticides = eutrophication, antibiotic resistance, high resource usage, if escape will out compete

Question 31

What is environmental monitoring?

Answer 31

Physical and environmental measurements made over a period of time. e.g. air quality, soil, water quality (chemical - pH, microbes) used to monitor the effect and impact of conservation

Question 32

Give an example of environmental monitoring and when it is needed

Answer 32

An environmental Impact Assessment is required before construction projects. Also used to make political decisions.
