"Let’s put an end to the transfer of lifestyles and consumer habits to the Third World that ruin the environment. Let human life be more rational. Let a just international economic order be implemented. Let science work toward a sustainable development without contamination".

"The world is facing so many political, military, energy, food and environmental problems that there is no country wanting the United States to return to extremist positions that would increase the risks of nuclear war."

In the face of climate changes, environmental damage caused by other factors, economic crises, epidemics and hurricanes, our material, scientific and technical resources are ever more abundant. The protection of our people will always take first place in our efforts. There could be no higher priority. 
"The farming land and the drinking water will be considerably reduced. The oceans will be contaminated and many marine species will no longer be edible while others will be extinct. This is not simply a logical assertion but the result of scientific research."
“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.”

“We trust in humanity; we trust in man. And humanity won't let itself be annihilated. It won't let its nature, its waters, its seas, its resources be annihilated.”

“It is worthwhile indicating that the main responsibility for the brutal destruction of the environment lies with the consumer societies. They are the offspring of the old colonial metropolises and of imperialist policies that also begot the poverty and backwardness which are today the scourge of the overwhelming majority of humanity.”

"I believe that, rather than weapons the peoples need ideas. They need a change from an inhumane, unsustainable global world that threatens life on the planet, to a just and humanitarian social order that offers humanity an opportunity to survive. The peoples need a world with a bit of drinking water and air to breathe where the necessary food is available and advanced technology can be used to produce housing, schools to educate the children, medicines to preserve human health and medical care indispensable to all, children, adolescents and the elderly".

"Let the ecologic debt be paid and not the foreign debt. Let hunger disappear and not man."
