        Health issues in Human

• Skin cancer risk increases.

• Can cause eye problems, especially cataracts.

• Weakens the immune system, making people more vulnerable to diseases.

• UV rays affect photosynthesis, reducing crop productivity.
• Damages plant DNA, affecting growth and yield.

Threat to Aquatic Life

• Affects phytoplankton (microscopic aquatic plants) which form the base of the aquatic food chain.
• Disrupts the entire marine ecosystem.
Damage to Materials

• Increases degradation of plastics, rubber, paints, and fabrics, reducing their lifespan.
