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.
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.
