This is a remote forest in Western Poland, where 400 pine trees have grown with a curvature in their trunk structure and it turns out that no one really knows exactly what caused it. There are, however, a few theories:

1) The main theory seems to suggest that this is the result of human interference. It is believed that this is a tree farm and the trees were forced to grow horizontally in their youth to make a carpenters life easier. The curved shape can be induced by laying a heavy object over a young tree stem. Phototropism will cause the stem beyond the heavy object to grow toward the sky, while the growing stem beneath and behind the heavy object will develop what is called morphogenetic compression wood - which ultimately makes the curv ...

Ever wondered why two of the world's most delicious fruits - the mango and the avocado - have such enormous seeds? Turns out they likely evolved to be swallowed whole by megafauna, like our modern-day rhinos and elephants, that once ruled the Earth, to be deposited far away from their host plant and wrapped in a fresh dollop of fertiliser. That's why these seeds are nicknamed 'ghosts of evolution'.

This beautiful mosaic of leaves is caused by a mysterious natural phenomenon known as 'crown shyness'. Seen here in a cluster of Kapur trees in Malaysia, scientists suspect that it occurs when young shoots become sensitive to touch, and stop growing once they graze other leaves.

This is an albino redwood tree, with white needles instead of green because it's unable to produce chlorophyll. In order to survive, albino redwoods must join their roots to those of a normal redwood to obtain nutrients. Found in Henry Cowell Redwoods State Park and Humboldt Redwoods State Park in the US, there are only around 20 known albino redwoods in the world, and their exact whereabouts have been kept secret as protection.

The Brazilian Jaboticaba tree well and truly takes advantage of all the surface area on its trunk by growing its sweet, grape-like fruits all over it. It's said to have evolved its trunk-fruit so animals could reach them and distribute the seeds.

A new international study estimates that there are more than 3 trillion trees on Earth, about seven and a half times more than some previous estimates. This number was formulated by collecting tree density information from more than 400,000 forest plots around the world. But the total number of trees has plummeted by roughly 46 percent since the start of human civilization. The results provide the most comprehensive assessment of tree populations ever produced and offer new insights into a class of organism that helps shape most terrestrial biomes.

Well, okay GOLD. Apparently, gold grows on eucalyptus trees. Researchers discovered that the trees are acting as a hydraulic pump, extracting gold from the soil and moving it to their leaves and branches. The ‘nuggets’ are about one-fifth the diameter of human hair, but the leaves may be used in combination with other tools to develop better exploration techniques.

In 2005 Swedish millionaire Johan Eliasch purchased a 400,000-acre (1,600 km2) area of land in the heart of the Amazon rainforest from a logging company for the sole purpose of it’s preservation.

Johan Eliasch, born in Sweden, is the Chairman and CEO of Head N.V. the global sporting goods group, and is the former Special Representative of the Prime Minister of the United Kingdom.

In 2005, Johan Eliasch created the Rainforest Trust and purchased for preservation purposes a 400,000-acre (1,600 km2) rainforest area in the heart of the Amazon rainforest near the Madeira River. Johan Eliasch co-founded Cool Earth in 2006, a charity he co-chairs, which sponsors local NGO's to conserve endangered rainforest and has over 120,000 registered members. ...
