Contaminación del agua

Human activities, such as the use of fertilizers and industrial waste, significantly pollute water bodies like rivers, lakes, and seas. Fertilizers lead to algae growth, reducing oxygen levels and harming aquatic life. Industrial waste, exemplified by the 2010 toxic sludge spill in Hungary, causes severe environmental damage. Household drainage also contributes to pollution if untreated. Solutions include reducing fertilizer use, managing industrial waste, and treating household drainage to ensure cleaner water and a healthier ecosystem.

What is one of the main consequences of using fertilizers in agriculture?

• Increased oxygen levels in water

• Improved water clarity

• Explosive algae growth

• Decreased crop yield

What was the impact of the toxic sludge spill in Hungary in 2010?

• It improved the water quality of the Danube River

• It caused the river to turn blue

• It killed many plants and animals in the river

• It had no significant environmental impact

What is the term used for wastewater from homes?

• Sewage

• Drainage

• Effluent

• Runoff

How can water pollution be reduced according to the video?

• By allowing untreated drainage to flow into water bodies

• By increasing the use of fertilizers

• By ignoring chemical waste from factories

• By carefully managing chemical waste and reducing fertilizer use

What is one of the processes used in treatment plants to clean water?

• Adding more nutrients

• Removing solid waste with filters

• Increasing algae growth

• Introducing more microorganisms
