land pollution Flashcards
source of plastics
household trash littering disposable water bottles
effects of plastics
aesthetic as it spoils beauty of environment
breed vectors of disease such as houseflies and rodents
endanger wildlife such as elephants eat plastic bags
control of plastics
reduce reuse recycle
laws penalties fines punishments enforcement wardens ema police incentives competitions to promote recycling
source of mining/quarrying
construction industry
looking for fossil fuels and other materials
effects of mining/quarrying
respiratory ailments due to dust
trash
holes release gases and toxic waste affecting our health
prone to landslides
control of mining/quarrying
stop demand for fossil fuels so supply will stop so no need for mining/quarrying
laws penalties
enforcement
reduce reuse recycle
only allowed to dig so far
source of insecticides and pesticides
farmers using products to control pests and keep plants safe
agriculture
effect of insecticides and pesticides
can stay on our foods ending up in our bodies
leak into ground ruining soil health
leak into water sources contaminating them
kills plants
kills organism beneficial to soil
control of insecticides and pesticides
use environmentally friendly pesticides such as natural ones so doesnt harm food soil water sources
find animal that eats what you do not want - biological control
source of deforestation
construction industry
agricultural expansion
recreational and urbanisation - clearing forest for a park
for resources
effect of deforestation
force animals to migrate from habitat leading to their death and extinction
aesthetics disrupted
food chains disrupted
reduces oxygen
control of deforestation
plant trees
support government laws to protect trees
laws penalties 3 r’s
source of soil erosion
human activities - farming and land clearing leaving soil vulnerable to erosion
natural - exposed to strong winds rain and flowing water
construction industry
agriculture
control of soil erosion
plant crops to act as coverage
mulching
use organic fertilisers
laws penalties enforcement incentive 3 r’s
effects of soil erosion
aesthetics
habitat loss
increased pollution
clogs waterways
causes decline in fish and other marine animals
sedimentation in streams and rivers
source of urbanisation
increase in population
migration
household waste - biodegradable and non biodegradable waste
factory waste - cardboard boxes
effects of urbanisation
odour
spread of disease
breeds vectors of disease such as rats roaches
more demand for buildings so more clearing of land
control of urbanisation
use less trash
3 r’s
implement better structure in countries so no need for migration
laws penalties enforcement incentive 3 r’s
source of metals
found in one heaving rocks that form a part of earths crust as outer layer on top of mantle
industrial plants
mining
effects of metals
deforestation
erosion
construction leads to increase of noise level and dust
contamination of soil
poisons food
bioaccumulation
control of metals
eco friendly equipment
shutting down illegal mining
improving mining sustainability
reducing demand for metals
use alternate source of energy
