Have you ever heard of agritourism where you can experience the farm life? If not, Dr.Cindy Ayers-Elliott will tell you the real story of Foot Print Farms.
The original concept of building Foot Print Farms was simple.When Ayers-Elliott returned to her hometown after graduation, she didn’t have to look any further than her state's alarming health statistics to find a mission.Everywhere she turned, there were reports of high blood pressure, diabetes, obesity and heart disease.“The problem was already identified, ”explains Ayers-Elliott.“Too many Mississippians were seriously unhealthy and it didn’t take research to see that.And many of the state's greatest health challenges could directly result from poor diet.”
These days, Foot Print Farms, which started with a few raised beds of herbs and vegetables, is making fresh, naturally grown food.“When speaking of the key to my success, the co-op model works because we share the work and rewards, ”notes Ayers-Elliott.“A perfect example is the Wingfield High School football team.To earn the money for equipment and other items, players committed to working five hours a week on the farm, and by the end of the summer they produced 1, 000 melons and the profits from their sales helped to buy weights, T-shirts, sweat suits and pregame meals.But the lessons they learned about the rewards of hard work and working together to accomplish something were even more valuable products of their efforts.”
“It's a model that can easily be learned in other places and I’m looking forward to seeing some of our current partners do just that—to take what they have learned here and spin it off in other communities.”Ayers-Elliott remarks.She is now looking forward to developing an agritourism area to the farm, where visitors can experience the farm life, learn new skills and take with them seeds of inspiration they can sow in their own communities when they return home.

Walk through the Amazon rainforest today and you will find it steamy, warm, damp and thick. But if you had been there around 15, 000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests might have reacted to the cold, dry climate of the ice ages, but till now, no one has reached a satisfying answer.
Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to solve global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 given off in the UK each year. But how will the Amazon react to the future climate change? If it gets drier, will it survive and continue to draw down CO2? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.
Unfortunately, collecting information is incredibly difficult. To study the past climate, scientists need to look at fossilized pollen (花粉) kept in lake mud. Going back to the last ice age means drilling down into lake sediment (沉淀物)，which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled (未取样)。So far, only a handful of cores have been drilled that go back to the last ice age and none of them provides enough information to prove how the Amazon forest reacts to climate change.
