Answer:
War, contagious diseases,and overpopulation. All of these lead to environmental degradation, poor nutrition and pollution. If a solution is not found quickly, these problems caused by the human race will cause humanity's end.
Answer:
It is striking how often people now speak of “a common humanity” in ethically inflected registers, or ethically resonant tones that express a fellowship of all the peoples of the earth, or sometimes the hope for such a fellowship.
It is also striking how often we speak of our humanity as something that is not given to us once and for all, as species membership is, but something towards which we are called upon to rise – not until such time as we achieve it, which could be different from one person to another – but unendingly, until we die.
The two seem interdependent: to recognise the humanity of others we must rise to the humanity in ourselves, but to do that we must at least be open to seeing fully the humanity of all people.
In a similar way, the acknowledgement of human rights – rights that all people are said to possess merely by virtue of being human – appears to be interdependent with the acknowledgement of a common humanity with them.
The same is true for the recognition of the “Dignity of Humanity” to which, we are told in preambles to important instruments of international law, an unconditional respect is owed, as it exists, inalienably, in every human being.
More often than not, we refer to the idea of a common humanity when we lament the failure of its acknowledgement. The forms of that failure are depressingly many: racism, sexism, homophobia, the dehumanisation of our enemies, of unrepentant criminals and those who suffer severe and degrading affliction.
As often as someone reminds us that “we are all human beings”, someone will reply that to be treated like a human being you must behave like one.
There are two kinds of explanations for this. Each has its place. One assumes that we retain a firm hold on the idea that all peoples of the earth share a common humanity, but for various psychological, social, moral and political reasons fail to live up to our acknowledgement of it.
The other suggests that the very idea of a common humanity waxes and wanes with us and at times – when we dehumanise our enemies or are vulnerable to racism, for example – becomes literally unintelligible to us.
