People and Their Environment: South America Managing Resources
While the use of natural resources has advanced economic growth and increased stability, it has also damaged the environment and the biodiversity of South America.
Deforestation has destroyed almost 20 percent of the Amazon rain forest, threatening nearly half of all animal and plant species on Earth.
Monoculture and soil erosion contribute to decreased soil fertility and desertification, which reduces the area of nutrient-rich soils and grasses needed to grow crops or to feed livestock. Monoculture= growing only one crop in an are depletes soil of nutrients- soil erosion Oxisols-severely depleted soils- in humid tropical areas can degrade into baked land if intensive ag
People and Their Environment: South America Human Impact
Urban growth and industrialization have created environmental pollution.
A lack of funding and organization often results in a city’s lack of adequate plumbing infrastructure necessary to deliver clean water and remove sewage.
Illegal mining activity has grown as the value of precious metals and raw materials has increased, exacerbating the pollution problem.
People and Their Environment: South America Addressing the Issues • Reducing the human impact on the environment is critical to protecting biodiversity and preserving the livelihood of the population. • Implementation of anti-deforestation laws and farming management practices are among the efforts underway to reduce drought and soil erosion. • South America’s countries are working together to address the problems related to urbanization, to reduce greenhouse gas emissions, to develop public transport systems, and to regulate the exportation of natural resources.
