Ozone depletion in the stratosphere can cause which of the following effects?

• A. Increased agricultural productivity
• B. Increased eye diseases
• C. Enhanced marine biodiversity
• D. Decreased skin cancer rates

Answer: (B)

The correct choice indicates that ozone depletion in the stratosphere can lead to increased eye diseases. This is due to the fact that the ozone layer plays a vital role in absorbing the sun's harmful ultraviolet (UV) radiation. When the ozone layer is depleted, more UV radiation reaches the Earth's surface, which can lead to a higher incidence of various eye disorders, including cataracts and other conditions that can impair vision.

The increase in UV radiation exposure is a significant health concern as it can contribute to not only eye problems but also skin issues and weakened immune responses. In this context, understanding the impact of ozone layer depletion is critical for public health awareness and safety measures.

Other effects such as increased agricultural productivity, enhanced marine biodiversity, and decreased skin cancer rates are not associated with ozone depletion. In fact, agricultural productivity may decline due to increased UV exposure harming sensitive crops. Marine biodiversity could suffer as UV radiation influences aquatic ecosystems negatively. Skin cancer rates actually increase with higher levels of UV radiation, contrary to what would be suggested by the incorrect options.
