Deforestation of vast tracts of tropical rainforest throughout Mesoamerica took place over several thousand years It is estimated that there were as many as 50 million people living in this region, with some 17 million in Mexico, alone, when the conquistadores arrived in the s.

Re-forestation of deserted regions previously inhabited by pre-Colombian civilizations e. Regions that remained populated continued to suffer the ecological consequences of deforestation ibidbut in the abandoned areas the re-growth of the rainforests in some parts of Central America was so complete that by nearly all of the major ancient cities and monuments lying between Panama and southern Mexico had been canopied under them.

Today, archaeological expeditions routinely discover previously unknown settlements and the life and times of the peoples that lived there, but they are hard-won victories, accompanied by much difficulty in navigating the dense growth that protect these treasures of the past from open view.

New finds are now often aided by sophisticated remote sensing technologies Along the northern border of the Brazilian jungle live the Yanomami.

These people have never been conquered by European colonialists. Left to evolve on their own without interference from the outside, they have formed a series of loosely knit tribes that have developed shifting agricultural methods to live off the land, mostly by hunting bush meat and subsistence farming, without causing permanent damage to the environment in which they must live Their farming methods do not include fire as a forest clearing mechanism.

Instead, they cut down the trees, creating large open circles. Then they burn the trees to get enough minerals to fertilize the cleared zone. They farm the nutrient-poor soils for several years, raising sweet potatoes, plantains, sugar cane, and tobacco, and then they move on.

By the time the Yanomami return to the same farming locale, some years later, the area has re-grown to its former state.

Without fire as a confounding factor, the Yanomami have achieved a rare a balance with the land in which crops are produced and forestland is repaired by a natural cycle that favors the survival of both sets of life forms. Many other cultures living close to the land were not as fortunate as the Yanomami to have conceived and implemented sustainable relationships with their surroundings and have paid the ultimate price, that of extinction They attracted thousands of hopeful immigrants from the eastern United States and Europe to that area of the west.

Over the next 20 years, rainfall was above average and farming flourished. However, the next years saw some of the worst droughts in recorded history for that region. The result was a systematic erosion of millions of tons of topsoil The situation intensified from with increasingly devastating results The weather patterns had conspired to defeat these early settlers in their quest to re-shape the landscape into productive farmland.

Lesions learned, no one returned to the dust bowl region for some 15 years. During the intervening period, nurturing precipitation regimens returned, and the assemblages of wildlife long absent re-populated the region.

Tall and short grasses re-built the soil enough to attract back the kit fox, antelope, prairie dog, and a wide variety of endemic birds and other support plants, reclaiming their niches and restoring the region to a mixed grasslands prairie.

Seeds of native plants that had lain dormant germinated and thrived when competition with cash crop species for limited resources ceased.

Following WWII, the area once again suffered ecological loss from the impacts of farming. This time that activity was supported by groundwater pumped from the Ogallala aquifer for irrigation of wheat, which requires additional water to achieve maximum yield Of course these turbines and solar panels are built using fossil fuels so they are just another ‘pie in the sky renewable resource.” The building of these turbines has nothing to do with renewable energy!

Orion Magazine | Dark Ecology When President Donald Trump announced on June 1 that he had decided to withdraw the United States from the Paris climate accord, he asserted that staying in the pact would prevent our nation from further developing its fossil fuel reserves.
