A Year on Planet Earth

Winter has begun and with less solar energy the northern hemisphere freezes, life is at its hardest; as the planet starts its incredible journey around the sun, Earth's northern pole tilts away from the warmth and light.

Spring is a season of opportunity - the great melt begins, and new life erupts. But for those animal families in the southern hemisphere conditions are getting harsher. Days grow shorter and animals must prepare for tougher times to come.

Autumn is the season of change. It offers a chance to begin again or take a new path in life. As the year draws to a close and winter returns, preparedness is key. For those that succeed, their place in the next year's circle of life is safe.
