TO BEAT ""SEA GRASS""

The video discusses the impact of enteromorpha, a type of seaweed, on oil transport by reducing ship speed and increasing costs. Biochemists in Yorkshire developed a new anti-fouling paint that effectively prevents marine organisms from clinging to ships. Led by Dr. Alex Christie, the team created a paint with a plastic vinyl base that poisons organisms before they develop into seagrass. The paint has been tested in both fresh and saltwater, proving its effectiveness. It offers significant cost savings for shipping companies by maintaining flexibility and not flaking off, unlike older copper-based paints.

What is the main issue caused by enteromorpha on ships?

• It increases the ship's speed.

• It causes the ship to sink.

• It reduces the ship's speed, increasing operational costs.

• It improves the ship's fuel efficiency.

Who led the team that developed the new anti-fouling paint?

• Dr. Sarah Johnson

• Dr. Emily Brown

• Dr. John Smith

• Dr. Alex Christie

What is the base material of the new anti-fouling paint?

• Steel

• Plastic vinyl

• Copper

• Aluminum

How long can two coats of the new paint keep a ship free from fouling?

• One year

• Two years

• Three years

• Four years

What is a key advantage of the new paint compared to old copper-based paints?

• It doesn't flake off and stays flexible.

• It is more environmentally friendly.

• It changes color over time.

• It is cheaper to produce.
