The earth is tilted at an angle of exactly 23.5 degrees to the sun. Without this tilt, the earth would be a very different planet. While there would still be climatic variations north to south caused by the varying concentration of solar energy reaching the planet’s surface, there would be no seasons and no variation in the hours of daylight and darkness during the year.

  • Tropical rainforests cover less than 3% of the planet’s surface but are home to more than 50% of the world’s species.
