By the late 1970s poaching and deforestation had reduced the gorilla population to 250.
Global climate change, driven by fossil fuel use and deforestation, is undermining the livelihoods of millions of people.
Overfishing and deforestation have been some of the main causes for the reduction in the number of threatened species.
Mr Fasanando says that this ambiguity encourages land grabs, migration and deforestation.
ECONOMIST: A scramble for land sets investors against locals
Indiscriminate logging and deforestation have caused the exposed soil to run off into the river, silting it up and reducing its water-flow capacity.
But as Brazil has come to take the issues of both climate change and deforestation more seriously, so its opposition to such a programme has moderated.
The day's focus was on environmental protection and the need for Latin America to do more to protect the natural environment, despite the pressures of population growth and deforestation.
There were once hundreds of elephants roaming this area, but hunting and deforestation have almost wiped out the population, with as few as one or two elephants remaining in the wild.
There are also some ecosystems, such as the boreal forests of Canada and Siberia and the Amazon rainforest, which are huge absorbers of carbon dioxide, but which are changing rapidly because of temperature increases and deforestation.
ECONOMIST: Two new satellites will monitor carbon-dioxide emissions
There have been movements for land rights and formation of states on the basis of language spoken by its people and against deforestation and commercial forestry in Himalayas and big dams.
At the intergovernmental level, Reducing Emissions from Deforestation and Forest Degradation (REDD) is a UN initiative to create a financial value for the carbon stored in forests, offering incentives for developing countries to reduce emissions by slowing deforestation and to invest in low-carbon paths to sustainable development.
The major threats are from coastal development, destructive fishing practices, overexploitation of marine resources, marine pollution and sedimentation from inland deforestation and farming.
For example, expanded credits for forestry-based offsets, including reforestation, afforestation and avoided deforestation, would give the rural poor a critical source of income to manage and sustain their landscapes.
ECONOMIST: On climate change, Bretton Woods, the Pope's speech | The
And that's at the same time that we're going to be hitting them with a lot of other challenges besides climate change - pollution and land use change, deforestation and fragmenting of the landscape.
The research was possible only because Brazil has good data on human development and on deforestation, which these days is measured by satellites.
But developing countries have no incentive to stop cutting down their forests, and tropical deforestation accounts for around 20% of total annual greenhouse-gas emissions.
In 1992 Mr Gore asserted that 20% of the Amazon had been deforested and that deforestation continued at the rate of 80m hectares a year.
For example: if a company somewhere in Africa chops down a forest to grow food destined for Europe, and that deforestation wrecks the water supply used by villagers, who's to blame - the Africans or the Europeans?
GHGs have risen from around 280ppm two centuries ago to around 370ppm today, thanks chiefly to mankind's use of fossil fuels and, to a lesser degree, to deforestation and other land-use changes.
Failure to ensure land rights for indigenous peoples and particularly women, will impede efforts to stop deforestation and mitigate climate change, say the authors.
We will take steps nationally and internationally, including under the Convention, to reduce emissions from deforestation and forest degradation and to enhance removals of greenhouse gas emissions by forests, including providing enhanced support to developing countries for such purposes.
Further insurance to ensure that greenhouse gas reductions from biofuels are significant can come from giving incentives ("the carrot") to developing countries to reduce deforestation and providing a stick of banning biofuel (and maybe all agricultural exports) from countries that don't meet deforestation reduction targets.
Large-scale defences are now being marshalled by governments, NGOs, scientists and investors, chief among them an international endeavour known as Reduced Emissions from Deforestation and Forest Degradation, or REDD.
The NGO made fresh allegations: that SMART, a palm-oil producer, a member of the RSPO and a part of Sinar Mas, an Indonesian conglomerate, was involved in illegal deforestation and clearance of peatland.
The effects of retreating glaciers on mountains and in polar regions, deforestation in South America and forest fires across sub-Saharan Africa are also shown in the atlas.

An important decision was to include in the new regime emissions from deforestation and land degradation.
Deforestation and habitat loss in Virunga because of illegal charcoal production continue to threaten key gorilla habitat.
Who cares about deforestation and melting polar ice caps, when it means God is just around the corner?
This will provide competition to the underlying causes of deforestation and reward those who implement sustainable forestry management.
But international money may start to flow through the UN's REDD (Reducing Emissions from Deforestation and forest Degradation) scheme.
