Citrus trees being removed for development

我们的旅行开始乘坐火车到西棕榈滩。汽车已经满了,我们相信我们通过乘坐火车来显着降低旅行的碳足迹。我们在棕榈滩县度过了两天,看着大西洋山脊上的城市地区,该部分已经为发展或农业排出的沼泽地,以及其他部分挖掘出水处理或储存。我们还访问了南佛罗里达水管理区总部和几种大规模的水管理和治疗项目。我们享受甜蜜的橘子和甘蔗,但我们还看到了绿色疾病围困的柑橘行业,甘蔗田已经失去了六英尺的表土,以及用巨大泵和化石燃料移动水的环境恢复项目。

Stan Bronson shows students sugar cane grown in the rich peat soils in the "Everglades Agricultural Area" south of Lake Okeechobee.  This area once was the heart of the everglades but has been drained and cropped, primarily with cane, for over fifty years

Soil loss in the agricultural area is dramatically illustrated by the concrete pole, imbedded in bedrock, and originally flush with the surface.  The peat, formed in the original everglades oxidizes and is lost when drained and used for agriculture.  Two thirds of the original soil is gone from this area

 

 

 

 

 

 

Grassy Waters Preserve was once part of the continuous Everglades wetlands, Now 20 square miles are walled off and water levels are maintained to maximize water supply for West Palm Beach and adjacent cities

A pump station for one of the massive storm water treatment areas (STAs).  Water is pumped into the STA and allowed to slowly migrate south, mimicking the natural flow in the original evergladesPumps used to move water into the STA.  The engineering of pumps, isolated wetlands, dikes and canals are all constructed to facilitate removal of nutrients from water destined for the Everglades

One of Florida's largest, this citrus grove is beset by greening's disease, and is in the process of being redeveloped as a residential area
