All Flashcards
What are the stages of sewage treatment?
Primary treatment (physical removal of solids), secondary treatment (biological breakdown of organic waste), and tertiary treatment (advanced filtration and disinfection).
Describe the recycling process.
Collection, sorting, cleaning, processing, and manufacturing into new products.
What are the steps involved in creating a modern landfill?
Site selection, preparation (lining), waste disposal, compaction, daily cover, leachate collection, gas management, and final closure.
How can reducing waste help protect the environment?
Minimizes resource depletion, reduces pollution from manufacturing and disposal, and conserves energy.
How can reusing items help protect the environment?
Reduces the need for new products, conserves resources, and lowers waste generation.
How can recycling help protect the environment?
Converts waste into new materials, reducing the need for raw materials and lowering energy consumption.
How can improving sewage treatment help protect the environment?
Removes pollutants from wastewater, preventing contamination of waterways and protecting aquatic ecosystems.
How can protecting wetlands help protect the environment?
Provides natural filtration of pollutants, supports biodiversity, and helps control flooding.
What are the effects of Eutrophication?
Algal blooms, oxygen depletion, fish kills, and reduced biodiversity.
What are the consequences of oil spills?
Death of marine life, habitat destruction, and economic losses for coastal communities.
What are the environmental problems associated with landfills?
Leachate contamination of groundwater, methane production, and habitat destruction.
What are the effects of thermal pollution on aquatic ecosystems?
Reduced oxygen levels, harm to aquatic organisms, and altered ecosystem dynamics.
What are the human health impacts of pollution?
Respiratory problems, cardiovascular diseases, cancer, neurological disorders, and endocrine disruption.
What are the environmental consequences of mining?
Habitat destruction, soil erosion, water pollution, and air pollution.
