Earth Has Lost Half of Its Trees Since Dawn of Civilization

EcoWatch: An international collaboration of scientists has just completed the ultimate green census--by calculating that the planet is home to 3.04 trillion trees. The latest estimate is far higher and almost certainly more accurate than any previous attempt. But the bad news is that humans are removing trees at the rate of 15 billion a year--and there are now about half as many as there were at the dawn of civilization. For every person on Earth, there are 422 trees--in total, more than 3,000 billion...

Ecologist: Isn't three trillion trees enough to keep our planet healthy? It sounds like a lot, writes James Dyke, but they are under threat as never before, from deliberate deforestation and climate change. Many of the 1.5 billion trees we are losing a year are in the last great rainforests - key ecosystems under threat of drying out forever under our escalating double onslaught. Humans are attacking the forest on a local front that follows new roads which open up previously undisturbed forest to logging,...

Monitor: When faced with deforestation statistics that seem daunting, the fact that there are 422 trees per person on Earth sounds a bit more reassuring. But is it? On Wednesday, researchers published the most comprehensive assessment of global tree populations ever conducted, revealing findings that blew previous estimates out of the water. Prior to the Yale-led study, Earth was believed to be home to 400 billion trees, but the new estimate is nearly eight times higher 3.04 trillion. Researchers arrived...

Mongabay: A new study published in Nature estimates the planet has 3.04 trillion trees. The research says 15.3 billion trees are chopped down every year. It also estimates that 46% of the world's trees have been cleared over the past 12,000 years. When it comes to the world`s forests, two of the commonly asked questions are "How many trees are are on Earth?" and "How many trees are cut down each year?" A new study proposes answers: three trillion and 15.3 billion. The research, published today...
