A Quote by Jared Diamond

Why were there far more species of domesticated animals in Eurasia than in the Americas? The Americas harbor over a thousand native wild mammal species, so you might initially suppose that the Americas offered plenty of starting material for domestication.
Eurasia's main axis is east/west, whereas the main axis of the Americas is north/south. Eurasia's east/west axis meant that species domesticated in one part of Eurasia could easily spread thousands of miles at the same latitude, encountering the same day-length and climate to which they were already adapted.
Measles and TB evolved from diseases of our cattle, influenza from a disease of pigs, and smallpox possibly from a disease of camels. The Americas had very few native domesticated animal species from which humans could acquire such diseases.
Eurasia ended up with the most domesticated animal species in part because it's the world's largest land mass and offered the most wild species to begin with.
I think there are a lot of opportunities in the Americas that matter deeply to 45 million Latinos in this country, and I would hope to be able to work to maybe elevate the profile of the Americas in our discussion about American global leadership.
Thousands of years ago, humans domesticated every possible large wild mammal species fulfilling all those criteria and worth domesticating, with the result that there have been no valuable additions of domestic animals in recent times, despite the efforts of modern science.
Even to this day, no native Australian animal species and only one plant species-the macadamia nut-have proved suitable for domestication. There still are no domestic kangaroos.
Livestock adopted in Africa were Eurasian species that came in from the north. Africa's long axis, like that of the Americas, is north/south rather than east/west. Those Eurasian domestic mammals spread southward very slowly in Africa, because they had to adapt to different climate zones and different animal diseases.
Increasingly, we will be faced with a choice: whether to keep the oceans for wild fish or farmed fish. Farming domesticated species in close proximity with wild fish will mean that domesticated fish always win. Nobody in the world of policy appears to be asking what is best for society, wild fish or farmed fish. And what sort of farmed fish, anyway? Were this question to be asked, and answered honestly, we might find that our interests lay in prioritizing wild fish and making their ecosystems more productive by leaving them alone enough of the time.
I have four relatively small children, and around fourth grade, they start doing big projects on Native Americas: everything is Native Americans in elementary school. Do you know how many Native American dresses I've sewn, on and on; it's a full yearlong study. And then never again. As journalists, we never even cover Native Americans.
I'm not encouraged by the silence. I can think of no benign reason for it. I'm afraid we may expect something closer to Christopher Columbus's arrival in the Americas than a scene from Close Encounters, and we all know how that turned out for the Native Americans.
The history of the Americas is one of constant warfare over salt.
For millions of years, on average, one species became extinct every century.... We are now heaving more than a thousand different species of animals and plants off the planet every year.
What worries me is that 'post-racial' America is not that different from the Americas that have preceded us, and it might not ever be.
There's still racism. Western Europe... has taken the native cultures of the Americas, the African cultures, the Asian civilization and lumped them together into The Others.
I know the value and significance of trading opportunities and have seen myself from Americas to the Far East the power of trade and open markets.
By 2050, at bio-extinction's current rate, between 25 per cent and 50 per cent of all species will have disappeared or be too few in numbers to survive. There'll be a few over-visited parks, the coral reefs will be beaten up, grasslands overgrazed. Vast areas of the tropics that have lost their forests will have the same damn weeds, bushes and scrawny eucalyptus trees so that you don't know if you're in Africa or the Americas.
