What are the harmful effects of ultraviolet (UV) rays and how does Earth protect us from them?
Ultraviolet (UV) rays from the Sun can be harmful to humans. Overexposure may lead to skin burns, aging, eye damage and even skin cancer. Fortunately, Earth is protected by a layer of ozone in the atmosphere, which absorbs and blocks most of the Sun’s dangerous UV rays. This ozone layer acts like aRead more
Ultraviolet (UV) rays from the Sun can be harmful to humans. Overexposure may lead to skin burns, aging, eye damage and even skin cancer. Fortunately, Earth is protected by a layer of ozone in the atmosphere, which absorbs and blocks most of the Sun’s dangerous UV rays. This ozone layer acts like a sunscreen for the entire planet. Preserving it is important to ensure the continued protection of all living beings from harmful solar radiation.

Human activities like burning fossil fuels and deforestation release greenhouse gases, which trap heat and raise global temperatures. Even slight increases can shift climate patterns, affecting rain, snowfall and ocean currents. Glaciers melt, sea levels rise and extreme weather events like heatwaveRead more
Human activities like burning fossil fuels and deforestation release greenhouse gases, which trap heat and raise global temperatures. Even slight increases can shift climate patterns, affecting rain, snowfall and ocean currents. Glaciers melt, sea levels rise and extreme weather events like heatwaves and cyclones become more frequent. These disruptions damage crops, displace animals and threaten human health. Understanding this link helps us reduce harmful practices and protect the planet’s delicate climate balance for future generations.
