and bred for new climates were way stations of ecological exchange
B. Global impact on food supplies
1. by the eighteenth century the ecological exchange made the world
better nourished
2. better equipped than before with medicinal drugs derived from plants
3. population explosion that has continued, with increasing pace, more or
