Planet Earth sustains life because of an amazing balancing act. Not too close or too far from the sun, the earth is the perfect temperature to have liquid water. The sun provides energy, but the ozone layer protects us from too much UV radiation. Earth’s magnetic field keeps our atmosphere, a delicate balance of gasses, from being blown away by solar winds. There is enough oxygen to sustain life, but not enough to make air flammable. There is also carbon dioxide to nourish plants, which sustain all other living things. Carbon dioxide, methane, and a few other“greenhouse gases” capture the sun’s heat, keeping Earth cozy. Too much of these gases will kill all life on Earth. Let’s maintain the balance!
