The current reduction of 0.1 in pH that has occurred over the industrial era translates to a 30 % increase in ocean acidity. This change has occurred at a rate that is about a hundred times faster than any change in acidity experienced during the past 55 million of years. A further decline of 0.3-0.4 pH units, projected for surface waters during the 21st century, represents a 100-150 % increase in acidity.
Think twice before buying more toys for your children.
Many of them are used only very shortly and then thrown away. Go for high-quality, long-lasting toys that can be used by several generations of children. Selling old toys on a flea market can give your toys a second life and can be much fun for you and the kids.
