The Interconnected Role of Oceans in Human Life and Ecosystems

The video discusses human dependence on ocean systems, highlighting the role of oceans in providing food, fresh water, and climate stabilization. It addresses issues like overfishing, pollution, habitat destruction, and climate change, emphasizing the need for sustainable practices and international cooperation to protect ocean ecosystems.

What is one of the primary ways oceans provide fresh water to land?

• Directly through saltwater

• Through the water cycle

• By desalination plants

• Through underground aquifers

How do oceans help stabilize the Earth's climate?

• By increasing atmospheric pressure

• By reflecting solar radiation

• By storing large amounts of heat

• By absorbing sunlight

What is a fishery?

• A method of sustainable fishing

• A type of fishing equipment

• An area with a large population of fish suitable for harvesting

• A place where fish are bred

What role do phytoplankton play in the ocean ecosystem?

• They create a large part of the oxygen that sustains animal life

• They are a primary food source for humans

• They are responsible for ocean currents

• They increase ocean salinity

What is one of the challenges in enforcing international treaties on overfishing?

• High cost of fishing equipment

• Difficulty in enforcement

• Lack of interest from countries

• Abundance of fish populations

What is a major consequence of excessive fertilizer runoff into oceans?

• Increased fish populations

• Algae blooms leading to dead zones

• Cleaner ocean water

• Decreased ocean temperatures

What is one way humans have attempted to help fish populations recover?

• By creating artificial reefs

• By increasing fishing quotas

• By introducing new fish species

• By removing all fishing restrictions

What is a significant problem caused by floating garbage in the oceans?

• It increases ocean temperatures

• It provides habitats for marine life

• It helps clean the ocean

• It is consumed by marine animals, causing harm

What is a potential impact of rising sea levels on human populations?

• More stable weather patterns

• Decreased ocean salinity

• Massive displacement from coastal cities

• Increased land area

How does increased carbon dioxide in ocean water affect marine life?

• It increases water acidity, harming coral and shell-creating organisms

• It makes the water less acidic

• It increases the survival rate of shell-creating organisms

• It helps coral reefs grow
