🌎 International Mother Earth Day – 22nd April Planet • Sustainability • Climate Action • Environmental Responsibility International Mother Earth Day , observed annually on 22nd April , recognizes the Earth and its ecosystems as our shared home. The day calls for global cooperation to protect biodiversity, combat climate change, and promote sustainable development. 🌍 Why Mother Earth Matters Provides essential natural resources Supports biodiversity and ecosystems Regulates climate and weather systems Sustains human life and economic activity Maintains ecological balance Protecting Earth is protecting ourselves. 🌱 Key Environmental Challenges Climate change and rising temperatures Deforestation and habitat loss Ocean pollution and plastic waste Air and water contamination Loss of biodiversity Sustainable action is urgently required. 🌿 Individual Action Reduce, reuse, and recycle Conserve water and energy Support sustainable p...
It
doesn’t! The oxygen level of the planet has varied quite dramatically in the
last 500 million years. It was 35 per cent during the Carboniferous period, around
300 million years ago; as the climate, cooled and land plants died off, oxygen
fell to as low as 12 per cent by the beginning of the Triassic. Back then, the
air at sea level would have felt thinner than at the top of the Alps today.
Burning
fossil fuels has reduced oxygen levels very slightly – about 0.057 per cent
over the last 30 years. Deforestation only has a small effect because when
rainforest is cut down, other plants are usually grown in its place. But it’s
marine phytoplankton (plant plankton), rather than trees, that produces about
75 per cent of atmospheric oxygen. Global warming will have a significant
impact on phytoplankton, which is a much more serious threat to oxygen levels.
