A Quote by Mikhail Gorbachev

If current technological processes continue without change, the environment will change, and we, the human species, will either have to mutate or even die, to disappear, as many species have disappeared.
Actors will change their face, will change their hair, will change their voice, will disappear into the role. A movie star doesn't disappear.
I want to challenge all of you as people of deep conscience, people who are environment stewards of the earth and oceans ... By changing what you eat, you will change the entire contract between the human species and the natural world.
The facts of microevolution [change within the species] do not suffice for an understanding of macroevolution [theorized change from one species to another].
Biology is a science of three dimensions. The first is the study of each species across all levels of biological organization, molecule to cell to organism to population to ecosystem. The second dimension is the diversity of all species in the biosphere. The third dimension is the history of each species in turn, comprising both its genetic evolution and the environmental change that drove the evolution. Biology, by growing in all three dimensions, is progressing toward unification and will continue to do so.
It's possible that we'll screw up the climate so badly that most of us will die and a few breeding pairs will remain somewhere in the arctic. What's more likely is that we'll continue remaking the planet, driving many species to extinction, killing millions of people through the indirect effects of climate change, making life even harder for the poor and powerless than it is now, and making it a little more difficult for the global middle class to live the lives to which they have become accustomed - in other words, business as usual, only worse.
All the things that we've done as a species have had a limited scope. We're talking about melting the ice caps, raising the level of the seas dramatically, changing the distribution of every other species on Earth, perhaps wiping out one-third or half of them. The changes at work are geologic in scale. The level of change required to deal with it is enormous, too. It will require change in every country. It will require a degree of global cooperation that we haven't seen before.
I recognize thart even you, yourself, will change. Your ideals will change, your tastes will change, your desires will change. Your whole understandings of who you are had better change, because if it doesn't change, you've become a very static personality over a great many years, and nothing would displease me more. And so I recognize that the process of evolution will produce changes in you.
Species evolve to meet the environment. An intelligent species changes the environment to suit itself. As soon as a species becomes intelligent, it should stop evolving.
Our species is on the verge of changes that will fundamentally alter what it means to be human... and we are the people driving that change.
The human species took a crucial step forward when its vocal musculature came under operant control in the production of speech sounds. Indeed, it is possible that all the distinctive achievements of the species can be traced to that one genetic change.
We are the most dangerous species of life on the planet, and every other species, even the earth itself, has cause to fear our power to exterminate. But we are also the only species which, when it chooses to do so, will go to great effort to save what it might destroy.
I think when you work on fossils, and you realize that a species is there, and it's abundant for quite a long period of time, and then at some point it's no longer there - and so, when you look at that bigger picture, yes, you realize that either you change and adapt, or, as a species, you go extinct.
Clearly, we are a species that is well connected to other species. Whether or not we evolve from them, we are certainly very closely related to them. A series of mutations could change us into all kinds of intermediate species. Whether or not those intermediate species are provably in the past, they could easily be in our future.
When biological technology becomes further advanced, human beings as we know them, will become a modified species. If we as human beings fail to include the possibility of this development in our overall, social evolution we will witness the decline of our species
Not one change of species into another is on record ... we cannot prove that a single species has been changed.
I don't think we have learnt to keep within the limits. They are quite elastic but there is a point beyond which they will break and then you will get a complete and massive change in the climate in which the survival of human species might not be compatible.
