All Flashcards
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.
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 at the source promote sustainability?
It minimizes resource consumption, energy use, and pollution associated with waste disposal.
How can recycling promote sustainability?
It conserves resources, reduces energy consumption, and minimizes the need for landfills.
How can reusing items promote sustainability?
It reduces waste, conserves resources, and minimizes the environmental impact of producing new items.
