The oil industry has a less-than-stellar environmental record in general, but it becomes even worse in tropical
rainforest regions, which often contain rich deposits of petroleum. The most notorious examples of rainforest havoc
caused by oil firms are Shell Oil in Nigeria and Texaco in Ecuador. The operations run by both companies degraded the environment and affected local and indigenous people by their activities. The Texaco operation in Ecuador was responsible for spilling some 17 million gallons of oil into the biologically rich tributaries of the upper Amazon, while in the 1980s and 1990s Shell Oil cooperated with the oppressive military dictatorship in Nigeria in the suppression and
harassment of local people.
The simplest and most reliable way to mitigation damage from oil operations would be to prohibit oil extraction in the tropical rainforest. But that is unlikely given the number of tropical countries that produce oil and the wealth of oil deposits located in forest areas. Thus the focus is on reducing pollution and avoiding spills through better pipeline management, reinjection techniques, and halting methane flaring. Limiting road development and restricting access can help avoid deforestation associated with settlement.
Fighting for the forest: The roadless warrior
The energy and technology sectors are investing heavily in alternatives to conventional fossil fuels, but early efforts to use crop-based biofuels have had serious environmental consequences.
While some believed biofuels—fuels that are derived from biomass, including recently living organisms like plants or their metabolic byproducts like cow manure— would offer environmental benefits over conventional fossils fuels, the production and use of biofuels derived from palm oil, soy, corn, rapeseed, and sugar cane have in recent years driven up food prices, promoted large-scale deforestation, depleted water supplies, worsened soil erosion, and lead to increased air and water pollution. Still, there is hope that the next generation of biofuels, derived from farm waste, algae, and native grasses and weeds, could eliminate many of the worse effects seen during the current rush into biofuels.

Good old-fashioned oil conservation is effective in reducing demand for oil products. After the first OPEC embargo
in 1973, the United States realized the importance of oil efficiency and initiated policies to do away with wasteful
practices. By 1985, the U.S. was 25 percent more energy efficient and 32 percent more oil efficient than in 1973.
Of course the
U.S. was upstaged by the Japanese who in the same period improved their energy efficiency by 31 percent and their oil
efficiency by 51 percent. Today the importance of oil to the economy continues to diminish. Despite the 51 percent growth in the American economy between 1990 and 2004, carbon emissions only increased 19% suggesting that those who insist that economic growth and carbon dioxide emissions move in tandem are wrong.
DEVELOP NEW TECHNOLOGY
The developed world can seek alternative methods to oil exploration, by developing new technologies
that rely less on processes that are ecologically damaging. For example, compressed natural gas is a cleaner-burning
fuel than gasoline, is already used in some cars, and is available in vast quantities. Electric cars are potentially even more environmentally sound.
To encourage investment in research and development of "greener" technologies, governments can help by eliminating subsidies for the oil and gas industry and imposing higher taxes on heavy polluters. While governments will play a role in cleaner-energy development, it is likely that the private sector will provide most of the funding and innovation for new energy projects. Venture capital firms and corporations have put billions into new technologies since the mid-2000s, while corporations are getting on board as well.
As experiences with biofuels have shown, there are often downsides to alternative energy sources. For example, hydroelectric projects have destroyed river systems and flooded vast areas of forests. Thus when undertaking any large-scale energy project — whether it's wind, solar, tidal, geothermal, or something else — it is important to conduct a proper assessment of its impact.
Admittedly, there are many challenges facing sustainable use of tropical
rainforests. In arriving at a solution many issues must be addressed, including the resolution of conflicting
claims to land considered to be in the public domain; barriers to markets; the assurance of sustainable development
without over-exploitation in the face of growing demand for forest products; determination of the best way to use forests; and the
consideration of many other factors.
Almost none of these economic possibilities can become realities if the rainforests are completely stripped. Useful
products cannot be harvested from species that no longer exist, just as eco-tourists will not visit the vast stretches
of wasteland that were once lush forest. Thus some of the primary rainforests must be salvaged for sustainable
development to be at all successful.

Peru delays oil drilling in the Amazon to consult with indigenous peoples
(05/20/2013) Peru has delayed auctioning off 27 oil blocs in the Amazon in order to conduct legally-required consultations with indigenous groups in the region, reports the Guardian. Perupetro S.A., Peru's state oil and gas company, has announced it will auction 9 blocs off the Pacific coast, but will hold auctioning off the controversial oil blocs in the Amazon rainforest at least until later this year.
Canadian government drops over $16 million on advertising its tar sands
(05/16/2013) The Canadian government has nearly doubled its advertising spending to promote the Alberta tar sands in an aggressive new lobbying push ahead of Thursday's visit to New York by the prime minister, Stephen Harper. The Harper government has increased its advertising spending on the Alberta tar sands to $16.5m from $9m a year ago.
Is it possible to reduce the impact of oil drilling in the Amazon rainforest?
(05/02/2013) Oil extraction in the Amazon rainforest has been linked to severe environmental degradation — including deforestation and pollution — which in some areas has spurred violent social conflict. Yet a vast extent of the Colombian, Peruvian, Ecuadorian, Bolivian, and Brazilian Amazon is currently under concession for oil and gas exploration and production. It seems clear that much of this hydrocarbon development is going to proceed whether environmentalists and human rights groups like it or not.
Ten U.S. cities pledge to kick fossil fuel investments to the curb
(05/01/2013) The cities of San Francisco and Seattle have pulled their money out of fossil fuel companies, taking a climate divestment campaign from college campuses to local government. The campaign group 350.org said on Thursday it had won commitments from a total of 10 cities and towns to divest from 200 of leading fossil fuel companies.
Citizen group finds 30 toxic chemicals in air following tar sands oil spill in Arkansas
(04/30/2013) Independent air samples by locals have yielded "a soup of toxic chemicals" in Mayflower, Arkansas where an Exxon Mobil pipeline burst on March 29th spilling some 5,000 barrels of tar sands oil, known as bitumen. Chemicals detected included several linked to cancer, reproductive problems, and neurological impacts such as benzene and ethylbenzene. Air samples were taken by community leader and University of Central Arkansas student April Lane a day after the spill. However, the Environment Protection Agency (EPA)'s and Exxon Mobil's air samples have yielded chemical levels below harm except in the direct clean-up area, according to the Arkansas Department of Health (ADH).
