Correct option is B
Correct option: (b), It protects us from harmful radiation.
The depletion of the ozone layer is a significant concern for humans due to the critical role the ozone layer plays in protecting life on Earth.
Here’s why it is a problem:
- Increased Exposure to Ultraviolet (UV) Radiation: The ozone layer absorbs and filters out most of the Sun's harmful ultraviolet (UV) radiation, particularly UV - B and UV - Crays.
- Health Impacts on Humans: Skin Cancer: Increased exposure to UV radiation, especially UV-B, is strongly linked to skin cancer, including melanoma, the deadliest form of skin cancer. Overexposure to UV rays causes damage to the skin cells' DNA, leading to mutations that can result in cancer.
- Environmental Impacts : Harmful Effects on Marine Lifemarine ecosystemsphytoplankton: Increased UV radiation affects , particularly (microscopic plants at the base of the food chain). Phytoplankton are crucial for the global carbon cycle and provide the foundation for most marine food webs. An increase in UV radiation can reduce their population, which disrupts marine ecosystems and food supplies.
- Impact on Biodiversity: sensitive ecosystemsbiodiversityProlonged exposure to excessive UV radiation can harm or kill many organisms, particularly those in such as wetlands, coral reefs, and forests. This can lead to a reduction in and the collapse of fragile ecosystems that provide essential services to humans (e.g., water purification, carbon storage, food, and medicine).
- Global Climate Effects: Ozone depletion not only affects human health directly but also has indirect consequences on global climate change. The interaction between ozone depletion and greenhouse gases in the atmosphere can affect global weather patterns and temperature regulation.
- Increased Cost for Protection: protective measuressunscreensprotective clothingmedical treatments With increased UV exposure, there would be a need for more widespread and costly , such as , , and for skin cancer and other UV-related health problems. This would increase the economic burden on individuals, healthcare systems, and governments.
