Human Environment Interaction In Latin America — Presentation Transcript
1. Human-Environment Interaction in Latin America
2. Agriculture Some areas engage in slash and burn farming in which an area’s vegetation is cut down and then burned. The ashes act as a fertilizer. Unfortunately, the soil is usually depleted in two or three years and can no longer grow crops. So farmers move on and slash and burn another section. The downside of this is that it destroys the forests.
3. Hilly and mountainous areas use terraced farming. This is where you carve steps into the hillsides and then farm on those steps. Reduces soil erosion since there’s no longer a steady slope.
4. Urbanization Many people in Latin America are migrating towards cities. They offer better job opportunities as well as better medical care and education than do the rural areas. This migration, however, can result in overcrowded cities and urban slums.
5. This overcrowding results in pollution problems, most especially from cars, difficulties with trash and sewage, and water shortages. The infrastructure can’t keep up with the growth.
6. Tourism Lots of it in Latin America… all the resorts, cruise ship tours, etc. The upside is that it brings money to these areas and provides employment where otherwise there may be none or little.
7. The downside is that it can stress the local resources. Many of the jobs are also not well-paying – they’re low-level service industry occupations. Most owners of tourist resorts are not in-country. Resentment can build between the tourists and the locals, in part because of the obvious income gap, but also because of irritation at constantly serving the tourists’ whims. http://www.slideshare.net/dewertgeo/93-human-environment-interaction-in-latin-america-presentation---------------------

Human-Environment Interaction The first inhabitants of North America were
nomads. Nomads are people who move from place
to place. These people probably came from Asia
over a land bridge that once connected what are
now Siberia and Alaska. It was called Beringia.
These early migrants moved over the land. They
hunted game and fish and gathered wild plants to
eat. Water was necessary for survival. So, these first
Americans made temporary settlements along
coastlines and near rivers and streams. They were
able to live in the extremes of temperature and
climate in North America. They also adapted to the
region’s many environments. These included
mountains, forests, plains, and deserts.
About 3,000 years ago, agriculture replaced
hunting and gathering as the primary method of
food production. Many early settlements became permanent. As people began to grow crops, they
changed the landscape to meet their needs. In
wooded areas, early farmers cut down trees for
houses and fuel. To plant crops, they plowed the
rich soil of river valleys. They dug ditches for
irrigation. Many of the plants that they were the
first to grow are now staples throughout the world.
These included corn, beans, and vegetables.More........................................... http://sharepoint.chiles.leon.k12.fl.us/welchb/Guided
