Predicted changes in soil organic carbon for croplands 1990–2080. The image on the left shows changes due to climate change only while the map on the right shows changes as a result of variations in net primary production and the advent of new technologies related to crop management (e.g. machinery, pesticides, herbicides, agronomic knowledge of farmers) and breeding (development of higher yielding varieties through improved stress resistance and/or yield potential) that result in yield increases.
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.
