Gold is undoubtedly one of the world's most important natural resources, a refuge asset par excellence and one of the world's rarest metals. Its importance within our economy is crucial, although many reservoirs are slowly beginning to deplete.

According to US Geological Survey, China remains the world's largest producer of gold, followed by Australia and Russia. Forget the gold rush of the old American West, today gold is mined mechanically in huge mines, open-pit basins in which many other metals besides gold are found.

In this short article, we will show you what are currently the 6 largest gold mines in the world according to data collected by Forbes, which cites the World Gold Council.

We are all realising that our way of life, the one our parents, who were born and raised especially after the Second World War, taught us, is no longer sustainable. There are too many of us in this world now, and nature can no longer provide us with everything we need.

Capitalism, or consumerism for short, is forcing us to submit to environmentally worn-out logics that would not be sustainable even in the long run, but are even less so in the short time we have left before everything falls apart. Our way of life must change radically if we are to allow the survival of mankind. For example, the introduction of the law in Europe allowing the sale of insect meal aims at exactly that, at sustainability.

Therefore, it is necessary for all of us, while there is still time, to change certain behaviours to help the world. Here, then, are some tips for leading a greener and more sustainable life.

A bear entered the backyard and frightened a man, David Oppenheimer, who was relaxing in his lawn chair: It happened in Asheville, in the Blue Ridge Mountains, North Carolina. The man posted the video on his Facebook channel.

The video begins with the man lying in his deckchair, unaware of what is about to happen.

The bear slowly approaches the man, but initially neither of them notices the other's presence. When the bear notices the man's presence it makes a short sound and then runs away, leaving the man with a loud thump in his chest. (Facebook: @David Oppenheimer)
