The key to understanding overpopulation is not population density but the numbers of people in an area relative to its resources and the capacity of the environment to sustain human activities; that is, to the area’s carrying capacity. When is an area overpopulated? When its population can’t be maintained without rapidly depleting nonrenewable resources.... By this standard, the entire planet and virtually every nation is already vastly overpopulated
Learning, like love, death and eating, are fundamental human activities. It's at the core of human existence and its character has a resilience of continuity that is part of what makes up human nature. That is not fundamentally going to change.
Ever since the beginning of modern science, the best minds have recognized that "the range of acknowledged ignorance will grow with the advance of science." Unfortunately, the popular effect of this scientific advance has been a belief, seemingly shared by many scientists, that the range of our ignorance is steadily diminishing and that we can therefore aim at more comprehensive and deliberate control of all human activities. It is for this reason that those intoxicated by the advance of knowledge so often become the enemies of freedom.
The human condition comprehends more than the condition under which life has been given to man. Men are conditioned beings because everything they come in contact with turns immediately into a condition of their existence. The world in which the vita activa spends itself consists of things produced by human activities; but the things that owe their existence exclusively to men nevertheless constantly condition their human makers.
Peace and the survival of life on earth as we know it are threatened by human activities which lack a commitment to humanitarian values. Destruction of nature and nature's resources result from ignorance, greed and lack of respect for the earth's living things.
Art is one of man's few serious activities.
I'm human. That's how humans spend their time, doing shitty things.
No longer can we consider what the artist does to be a self-contained activity, mysteriously inspired from above, unrelated and unrelatable to other human activities. Instead, we recognize the exalted kind of seeing that leads to the creation of great art as an outgrowth of the humbler and more common activity of the eyes in everyday life. Just as the prosaic search for information is "artistic" because it involves giving and finding shape and meaning, so the artist's conceiving is an instrument of life, a refined way of understanding who and where we are.
I believe technology serves us best when it gives us more time to do things that are uniquely human. This includes activities that are enjoyable, creative, and productive.
The family only represents one aspect, however important an aspect, of a human being's functions and activities. A life is beautiful and ideal or the reverse, only when we have taken into our consideration the social as well as the family relationship.
The activity of God, which is transcendent in blessedness, is the activity of contemplation; and therefore among human activities that which is most akin to the divine activity of contemplation will be the greatest source of happiness.
Ultimately, all human activities have as their goal the realization of happiness. Why, then, have we ended up producing the opposite result? Could the underlying cause be our failure to correctly understand the true nature of happiness?
During these last ten thousand years, we have made massive, unprecedented changes to the environment, creating problems for ourselves that we may not be able to solve.
The fact is that gardening, more than most of our other activities except sometimes love-making, confronts us with the inexplicable.
Any educated person recognizes that curiosity and creativity aren't just important; they are among the essential human activities.
The city of Chandigarh is planned to human scale. It puts us in touch with the infinite cosmos and nature. It provides us with places and buildings for all human activities by which the citizens can live a full and harmonious life. Here the radiance of nature and heart are within our reach.
When cities were first founded, an old Egyptian scribe tells us, the mission of the founder was to 'put gods in their shrines.' The task of the coming city is not essentially different: its mission is to put the highest concerns of man at the center of all his activities.
We do not know how much of the environmental change is due to human activities and how much [is due] to long-term natural processes over which we have no control.
In the whole range of human activities, war most closely resembles a game of cards.
We have never been in danger of running out of resources, but we have encountered considerable dangers from people who say we are running out of resources and who say that human activities need to be constrained.
If we continue to set human borders and the economy as our highest priorities, we will never come to grips with the destructiveness of our activities and institutions.
Relative to most of the energy and material flows on Earth, the machinations of humankind are puny. The planet's powers are much, much bigger than our own. But in a few sensitive places, we're making an impact on a planetary scale, and that impact is not a good one.
How many people eat, drink, and get married; buy, sell, and build; make contracts and attend to their fortune; have friends and enemies, pleasures and pains, are born, grow up, live and die - but asleep!
There is scientific evidence that demonstrates there is some impact from human activities. However I don't think the evidence is conclusive.
Is civilization progress? The challenge, I think, is clear; and, as clearly, the final answer will be given not by our amassing of knowledge, or by the discoveries of our science, or by the speed of our aircraft, but by the effect of our civilized activities as a whole have upon the quality of our planet's life-the life of plants and animals as that of men.
