“our future depends on our actions as a species.”

Listen, Little Man! (1948)
Context: Every physician, shoemaker, mechanic or educator must know his shortcomings if he is to do his work and make his living. For some decades, you have begun to play a governing role on this earth. It is on your thinking and your actions that the future of humanity depends. But your teachers and masters do not tell you how you really think and are; nobody dares to voice the one criticism of you which could make you capable of governing your own fate. You are "free" only in one sense: free from education in governing your life yourself, free from self-criticism.

Letter to the minister of a church in Brooklyn (20 November 1950), p. 95. The minister had earlier written Einstein asking if he would send him a signed version of a quote about the Catholic church attributed to Einstein in Time magazine (see the "Misattributed" section below), and Einstein had written back to say the quote was not correct, but that he was "gladly willing to write something else which would suit your purpose". According to the book, the minister replied "saying he was glad the statement had not been correct since he too had reservations about the historical role of the Church at large", and said that "he would leave the decision to Einstein as to the topic of the statement", to which Einstein replied with the statement above.

Context: The most important human endeavor is the striving for morality in our actions. Our inner balance and even our very existence depend on it. Only morality in our actions can give beauty and dignity to life. To make this a living force and bring it to clear consciousness is perhaps the foremost task of education. The foundation of morality should not be made dependent on myth nor tied to any authority lest doubt about the myth or about the legitimacy of the authority imperil the foundation of sound judgment and action.

The statement "The future of all life, including our own, depends on our mindful steps." and much of the theme of this essay also occur later in his writings, including The World We Have : A Buddhist Approach to Peace and Ecology (2008), Ch. 1 : The Bells of Mindfulness, p. 3
The Sun My Heart (1996)
Context: All life is impermanent. We are all children of the Earth, and, at some time, she will take us back to herself again. We are continually arising from Mother Earth, being nurtured by her, and then returning to her. Like us, plants are born, live for a period of time, and then return to the Earth. When they decompose, they fertilize our gardens. Living vegetables and decomposing vegetables are part of the same reality. Without one, the other cannot be. After six months, compost becomes fresh vegetables again. Plants and the Earth rely on each other. Whether the Earth is fresh, beautiful, and green, or arid and parched depends on the plants.
It also depends on us. Our way of walking on the Earth has a great influence on animals and plants. We have killed so many animals and plants and destroyed their environments. Many are now extinct. In turn, our environment is now harming us. We are like sleepwalkers, not knowing what we are doing or where we are heading. Whether we can wake up or not depends on whether we can walk mindfully on our Mother Earth. The future of all life, including our own, depends on our mindful steps.
