The Ozone Layer: Protecting Ourselves from the Sun's Fury The ozone layer, a fragile shield in the Earth's stratosphere, protects us from the harmful ultraviolet (UV) radiation emitted by the sun. This radiation can cause sunburn, skin cancer, cataracts, and damage ecosystems. Understanding the threats to the ozone layer and international efforts to mitigate them is crucial for safeguarding our planet.
Leprosy, also known as Hansen's disease, is a chronic infectious disease caused by the bacterium Mycobacterium leprae. It primarily affects the skin, peripheral nerves, and mucous membranes. Though not highly contagious, leprosy can cause nerve damage and deformities if left untreated. However, early diagnosis and treatment can prevent disability and ensure a normal life for the affected individual.
