"They have poisoned oceans and rivers and contaminated the air; they have weakened and opened holes in the ozone layer and saturated the atmosphere with gases that impair climate conditions with catastrophic effects that we are starting to feel".

"An important biological species is endangered due to the accelerated and progressive destruction of its natural living conditions: man".

"World politics and economics moved forward at such a blind and chaotic pace that concepts like the environment, biological diversity, the preservation of nature, dessertification, holes in the ozone layer and climatic changes were barely known or even mentioned a few decades ago. Under a system of anarchic and chaotic production, which eventually gave rise to the current state of imperial, hegemonic and unipolar control, enormous amounts of resources were squandered, nature was significantly damaged, and absurd and unsustainable models of consumption were established, which constitute really unattainable dreams for the immense majority of those who living on the planet today and those who will live on it tomorrow".

"The crisis will have an especially negative impact on the struggle for sustainable development, the preservation of the environment and the protection of nature from the merciless destruction to which it is being subjected, and which is causing the poisoning of the waters and the atmosphere, the destruction of the ozone layer, deforestation, desertification, and the extinction of animals and plants. How could this possibly not be taken into the slightest account?"

"Hardly 30 years ago, few people in the world discussed the environment. Ideas or themes linked to the destruction of the forests, soil erosion and salinity, climate change, the disappearing ozone layer, melting icecaps, whole cities and nations doomed to fatally disappear beneath the sea, polluted air and water; overexploited oceans seemed to be inventions of doomsday scientists and not pressing realities".

“Men do not make history. Subjective factors can accelerate or delay major events, even for relatively long periods, but they are not a decisive factor, nor can they prevent the final outcome. Extremely serious accidents of human or natural origin, a nuclear war, the accelerated destruction of the environment and a relatively abrupt change in the climate can alter all estimates and forecasts made by the most visionary talents of our species. All of these things could still be avoided.”

"(...) many things threatening the life of the planet today, aside from war, like climate changes, the destruction of the ozone layer, global warming, the poisoning of the air, the rivers and the seas. These things threaten the life of the entire planet, thus all of the peoples have a common cause with the people of Latin America, North America and Europe".

"[...…]let the poor countries receive some financing to produce ethanol from corn or any other foodstuff and very soon not a single tree will be left standing to protect humanity from climate change.."

“The idea of global warming hanging over our species’ life like a sword of Damocles was not even known by the immense majority of the inhabitants of our planet thirty years ago; even today there is great ignorance and confusion about these issues”

The accelerated pace of scientific research in all fields of material production and services, under the economic order imposed on the world following World War II, has led humanity towards an unsustainable situation. 

It is our duty to demand the truth. The populations of all countries have the right to know the factors causing climate change and the current scientific possibilities to reverse the tendency, if indeed we still really have any.
“Peoples must struggle to protect not just their economy, their rights; they must struggle to defend their very survival.  The environment is being swept away, it’s being destroyed.  Only one year ago, Mitch went through Central America with devastating results, and now we see pictures of colossal floods, a visible climatic change that nobody can deny any more.  Who does this hit before anybody else? The poorest countries, the countries of the Third World.”
“Today, the world is facing serious and pressing problems. The entire humanity is threatened by climate change. (...) The Third World countries are rightly claiming from the richest and most developed nations hundreds of billion dollars a year to pay for the climate battle”.
