gracias al uso de los recursos por parte del ser humanos se han visto impacto ambientales desde tiempos inmemorables. a medida que iban evolucionando estos iban aumentando sus niveles de contaminación, gracias a la agricultura se mitigaron este tipo de impactos, pero esto no duro mucho tiempo ya que actualmente el hombre utiliza insumos para aumentar el rendimiento de los cultivos ya que debido al aumento poblacional deben buscar la manera de mantener con mucha comida a toda la población que tiene la tierra. esto se resaltó en la época del 29 en el siglo pasado cuando se dio la primera revolución industrial.
This has to do with the way resources are allocated i a community.e.g Project management allocation.
What is strategic planning?
What is human resource?
Humans have always made an impact on the environment through their use of resources. Early humans were primarily hunter-gatherers who used tools to survive. They fashioned wood and stone tools for hunting and food preparation, and used fire for cooking. Early humans developed methods for changing habitat to suit their needs and herding wild animals.
As time passed, humans developed more tools and techniques and came to rely on that technology in their daily lives. Although the tools of early humans were primitive by today's standards, they significantly affected the environment and probably hastened the extinction of some large Ice Age mammals.
After the end of the last Ice Age, some eight to 10,000 years ago, humans began domesticating wild animals and plants. The first known instance of farming started in a region extending from southeastern Turkey to western Iran, known as the fertile crescent.
These early farmers domesticated crops such as chickpea, bitter vetch, grapes, olives, barley, emmer wheat, lentils, and flax. They hybridized wheat for making bread from wild grass and emmer wheat. They also domesticated animals such as sheep, goats, cattle and pigs.
The fertile crescent's unique diversity of wild crops and animals offered humans a mix of basic agricultural commodities that allowed a revolution in the development of human society.
The next major cultural change, the Industrial Revolution, began in England in the mid-18th century. It involved a shift from small-scale production of goods by hand to large-scale production of goods by machines. Industrial production of goods increased the consumption of natural resources such as minerals fuel, timber and water by cities.
After World War I, more efficient mass production techniques were developed, and industrialization became prevalent in the economies of the United States, Canada, Japan and western Europe.
Advanced industrialization leads to many changes in human society, and some of those changes negatively affect the supply of natural resources and result in environmental degradation. These changes include:
• increased production and consumption of goods by humans,
• dependence on non-renewable resources such as oil and coal,
• production of synthetic materials (which may be toxic or non-biodegradable) and
• consumption of large amounts of energy at home and work.
Other changes may have positive benefits. These include:
• creation and mass production of useful and affordable products,
• significant increases in the average Gross National Product per person,
• large increases in agricultural productivity,
• sharp rises in average life expectancy and
• a gradual decline in population growth rates.
