Man kind is responsible for hisself and all creatures and the

wellbeing of the world. For this reason we must also demand of

scientists, the scientific care of the environment as the first

moment of self control. Mankind in all its dealings with all

species of flora and fauna has the duty to take responsibility

for all of life's precious gifts in all its multiple forms.

The representatives of the great religions of the world

(in terra mater, Gubbio 1982)

We all well know that the areas of misery and famine that exists

on our planet could have been handled in a short time if the

enormous investments in arms, that serve only for war and

destruction, had been instead changed for investments in

nutrition and food, that serve life

Pope John Paul II (1979)

It is an arrogant preconception that mankind is the master of all

inferior creatures. On the country having been given the greater

things in life, it must become the educators of all lower animal

What would man be without animals? If all animals disappeared man

would succumb to a state of solitude Since all that happens  to

animals sooner or later happens to mankind. All things are tied

together.

There isn't any animal species on earth that does not constitute,

like you, a part of community.

Mohammed, Koran, VI 38

Nature doesn't take care of possible mistakes; it can do no more

than function equally, in eternity, without taking care of  that

which it can become.

There are precious treasures in the house of the just, but

mankind imprudently wastes them.
