People first domesticated wild animals and plants more than 10,000 years ago. The first peoples of North America quickly learned to farm using hand- and animal-power. As technology developed, farming machines were invented. These helped develop farming in many regions of North America previously too difficult to cultivate. From 1840 to 1880, Wisconsin USA became the breadbasket of America, and crop- and livestock-farming developed quickly. The village of Monticello is famous for its dairy farming and cheese. The community is still largely based on this. It has a population of about 1,200 people and is the focus of this book about life in a farming community.
This title looks at offshore fishing. Around the coast of much of North America, fishing stocks have greatly declined as a result of overfishing, pollution, and global warming.

They soon set up a fishing and shipbuilding industry. The community grew until about 1980, when the fishing industry largely stopped. Since then, the community has had to reinvent itself. It is still largely based on the old industries, but tourism is as important. Lunenburg has a population of about 3500 people.
