Wastewater treatment ;
brief description
Encompass the various processes we use to grow crops and raise livestock for food for human populations.
Is the contamination of the environment with harmful substances.
Wastewater treatment cleans wastewater to protect the environment and public health
3 impacts :
Agriculture
Farmers have an increased prevalence of many acute and chronic health conditions including : cardiovascular and respiratory disease, arthritis, skin cancer, hearing loss, amputations,......
3 positive effects :
3 negative effects :
-Preserve and restore critical habitats.
-Help protect watersheds.
-Improve soil health and water quality.
-Greenhouse gas emissions.
-Degraded soils.
-Deforestation.
3 causes :
-Climate change.
-Pollutes air and water.
-Depletes soil fertility.
3 solutions :
-Reduce plowing.
-Protect soil year-round with cover crops and more complex crop rotations.
-Incorporate deep-rooted plants on and around farms to hold nutrients and water.
3 impacts :
POLLUTION
3 positive effects :
3 negative effects :
-Air pollution affects climate.
-Cardiovascular disease.
-Cancer.
-Air pollution helps plants grow.
-Air pollution keeps polluted cities cooler in the summer.
-Oil sludge used as food for protein-producing microorganisms.
-Greenhouse gas emissions.
-Water, soil, air,..... pollution.
-Affect the health of people, plants, animals,.....
3 causes :
3 solutions :
-Smoke and dust from factories, vehicles,....
-Household waste, forest fire,.....
-Untreated waste is discharged into rivers, lakes,...
-Waste treatment, limit dust emissions into the environment.
-Plant more trees, green bare hills.
-Use public transport or electric vehicles that do not emit smoke and dust.
3 impacts :
Wastewater
treatment
3 negative effects :
3 positive effects :
-Waste reduction.
-Environmental protection.
-Energy production.
-Energy consumption.
-Sludge management.
-Chemical usage and discharge.
-Nutrient imbalance.
-Ecological disruption.
-Construction costs.
3 causes :
3 solutions :
-Untreated water cannot be used because of active ingredients, waste.
-Water is not stored, leading to scarcity.
-Floods, droughts.
-Sludge treatment.
-Water conservation.
-Biology.
