Global warming

 

Throughout history, the universe has followed natural laws, which likely influenced early religions in shaping societal codes of conduct. These laws have helped maintain order among billions of people, fostering a more peaceful existence. 

When the Sun formed, its gravity pulled in surrounding particles, causing collisions that created heavier elements. These elements sank to form Earth's core, while lighter materials formed the crust. Initially, Earth’s atmosphere consisted mainly of hydrogen and helium, with no magnetic field to shield it from solar winds and radiation. Over time, the planet cooled, volcanic eruptions released gases into the atmosphere, and nitrogen formed. As Earth rotated, the movement of liquid metal in its outer core generated a magnetic field, which now protects the planet from solar winds. Without this field, Earth's atmosphere would have been stripped away, making life impossible due to extreme radiation exposure. 

Life began about 3 billion years ago with bacteria, followed by the evolution of cells and plants, which gradually altered Earth's atmosphere. Greenhouse gases formed a protective layer, trapping heat and maintaining a stable climate. The Sun warms the planet during the day, and while some heat escapes into space, greenhouse gases retain enough warmth to sustain life. 

The Agricultural and Industrial Revolutions allowed humanity to shift focus from survival to technological and scientific advancements. This progress improved healthcare, reduced mortality rates, and increased prosperity—but also led to overpopulation and a higher carbon footprint. The Happy Planet Index provides insight into how well we balance happiness with environmental sustainability. 

However, modern lifestyles and deforestation continue to increase greenhouse gas emissions, exacerbating global warming. Every time we flip a switch, a turbine burns more fossil fuel, releasing carbon dioxide into the atmosphere. While reducing fossil fuel consumption is essential, the root problem is our disregard for nature. We must allow Earth to regenerate before exploiting its resources further. 

Paradoxically, trees—our greatest allies—are being destroyed at an alarming rate. The oceans attempt to compensate by absorbing excess carbon, but this warms the water, endangering marine life and coral reefs. Though often described as a fragile blue planet, Earth has survived asteroid impacts and other catastrophes, regenerating each time. The true fragility lies not in Earth, but in humanity itself. If we fail to recognize this and take immediate action, future generations may never get the chance to call Earth home.
