Good news! For the first time, direct satellite observations of the ozone hole over Antarctica have shown that ozone-destroying chlorine levels are declining and the ozone hole is recovering.
The chlorine decline results from the Montreal Protocol, an international ban on chlorine-containing chemicals called chlorofluorocarbons (CFCs), released by human activity. This has resulted in about 20 percent less ozone depletion than there was in 2005 — the first year that NASA's Aura satellite measured chlorine and ozone during the Antarctic winter.
Because chlorofluorocarbons take many years to break down, they will remain in the atmosphere for some time, continuing to deplete ozone. However, this study provides definitive evidence that the ozone layer will continue to heal in the future.

The global meat production and consumption have increased 20 percent in just the last 10 years, with harmful effects on the environment and public health as well as on the economy, according to research done by Worldwatch Institute. Large-scale meat production also has serious implications for the world’s climate. Animal waste releases methane and nitrous oxide, greenhouse gases that are 25 and 300 times more potent than carbon dioxide, respectively. Reduce the meat consumption seems to be the only solution.
