National Geographic have been to the western slope of the Sierra Nevadas in Califor-nia, roughly 2000m above sea level to photograph a tree. Big deal. Except that this giant se-quoia is over 75m tall, 8m around and sprouted at the very beginning of the Iron Age, some 3200 years ago.
If we can only choose one pest that made the news this year in dramatic fashion, then it goes without saying that we’ll choose alge. During the summer, the largest ever recorded algal bloom turned the Yellow Sea in China green – over 11,000 square miles of algae was recorded, and more than 19,000 tonnes of growth had to be removed from beaches.
