Photos from Suriname

By John Potter

Go to Indian Village

I want to share some photos I shot in Suriname. They can also be accessed through the Panoramic Photography page and the Google Earth file where you can get a better idea of their locations.

This is the fourth in a series of articles I’ve written for EcoHearth.com about the perils facing fresh water supplies.
I hope you enjoy it.

Fresh Water Supplies At Risk, Part 4: Water Conservation

Although environmental protection and restoration can provide us with cleaner water and lots of it, that doesn’t negate the benefits of conservation. In many—if not most—places, conservation is essential to ensure ample water for everyone’s use. It may seem an obvious statement, but conservation by consumers costs less and has a smaller impact on the environment than any other method of maintaining the flow of clean water to consumers.

Conservation means protecting and preserving, not wasting—but it doesn’t necessarily mean going without. Asceticism is an effective method of conserving, but the general population is unlikely to embrace that approach. Smaller steps and better, less-invasive methods are more likely to be accepted en masse.

In places such as Las Vegas and most of Florida, freshwater resources have always been limited. Now they are spread even thinner under the stress of booming populations, extravagant lifestyles and public policy that hasn’t changed to accommodate the new conditions. There are two obvious methods of conserving water in these types of places (and any other for that matter): stop wasting water and use what is available more efficiently.

Fresh Water Supplies At Risk, Part 3: Repairing the Water Cycle

Not all solutions to our clean-water supply problems require enormous and complex man-made engineering endeavors. The water cycle was here on Earth before man, and it has worked just fine for millennia. Sometimes the best thing we can do is return our planet to its original state (or as close as possible) and let nature repair itself.

Water moves through watersheds, or drainage areas, which act like giant geographic funnels pulling all of the surrounding surface water to a river or stream. Environmental factors within each watershed directly affect the quality of water passing through it.

Nature’s way of purifying water is through filtration, sedimentation, organic breakdown of materials, ion-exchange, oxidation-reduction and sorption-desorption. Some of these methods are not dissimilar to those we use in purification and waste treatment, but are much better. The big difference is that nature works more slowly than man-made systems; in fact, the more slowly the process proceeds, the more effective the purification.

Part 2: Groundwater on EcoHearth.com

Fresh Water Supplies At Risk, Part 2: Groundwater

Only one-percent of liquid freshwater is on the surface of the Earth; 99% is underground, held in what are called aquifers, water-bearing rock layers that serve as vast natural warehouses of fresh water. Aquifers can be found virtually everywhere on the globe, but they aren’t always easily accessible, and those that are can be more susceptible to contamination. Once an aquifer has been contaminated, it is not easy to return it to its original state. The “out of sight, out of mind” quality that makes them easy to pollute also makes them difficult to clean.

Potential aquifer contamination is why gas stations have such strict rules regarding their underground tanks. Even the small puddle of oil under your car in the parking lot has the potential of seeping into the ground and coming out of your kitchen faucet.

Other major threats include fertilizer leaching into groundwater, pesticide intrusion and landfill seepage. Many of these hazards are lessened by good regulation and best practices as well as improved technology, but there are many other steps that can be taken to preserve these essential underground ecosystems.
