Of all the planets in our universe. There is only one we know can support life. Just the right distance from its sun. With the perfect climate. It’s been called the lucky planet.

Without that crucial tilt everything would have been different. For it created the seasons, extrems of climate, hot and cold, and landscapes spectacular beauty. The perfect conditions for life on earth.
All life on earth is built on chance and palled by the sun. But the delicate balance is about a world of fortune. As the planet struggles to support owr growing demandes. This is the time to take stock of have and what we stand to loss.
