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.
The ever-growing energy demand necessitates exploring sustainable and efficient ways to meet our needs. Hydroelectricity, a well-established renewable source, and non-conventional energy sources like solar, wind, and geothermal energy, are gaining traction as we strive for a cleaner and more secure energy future. This essay will delve into hydroelectricity and non-conventional energy sources, exploring their potential, limitations, and role in a sustainable energy mix.
