Munch, munch. Tiny insects are at work. They crunch on citrus trees. Farmers don’t know until it is too late.

It infects the trees with bacteria. Scientists have trained dogs to sniff out this disease. Dog noses can catch it much faster than farmers can. Will people find a cure? Or will there be less orange juice? The tree of life described in Revelation 22:2 never will get sick. It will have “twelve kinds of fruit, yielding its fruit each month.”
