Became of today’s humanity. Replaced/displaced all other humans.

Before the rise of humanity and industrial agriculture, the interplay of life, climate, and land masses created the that fed oceanic ecosystems. However, during the Cambrian Explosion the land was largely barren, as life had yet to significantly invade land. Also, have always been key hosts for oceanic ecosystems, as sunlight could reach the seafloor and nutrients were closer to the surface. When supercontinents broke apart or formed as the tectonic plates danced across Earth’s crust, shallow seas were often created, which were usually quite life-friendly. Those ancient shallow seas and swampy continental margins have great importance to today’s humanity, as our fossil fuels were usually created there. Earth’s were created in swampy floodplain conditions, usually near coasts, and the oil deposits were created by and that . The and its predecessors (, ) had a half-billion-year history that began in the Ediacaran, and the Tethys finally disappeared less than 20 mya. The shallow margins of those tropical oceans, and the anoxic events that dotted the eon of complex life, formed most of today’s oil deposits, and . Numerous shallow tropical seas .

Mass extinctions always have critical geophysical aspects to them, and often geochemical. Continental shelves under shallow seas, which are home to most marine life, are vulnerable to sea level and oceanic current changes. Stagnant waters, or waters that have too many nutrients dumped into them, can lose their oxygen, which triggers anoxic events that kill complex life. A continental shelf exposed to the atmosphere by a falling sea level would obviously lose its marine life, and that marine life might have had nowhere else to go. Sea levels can rise or fall for different reasons. The most obvious reason has been advancing and retreating ice sheets, as water is removed from or added to the oceans, but the aggregate continental landmass has always grown (possibly sporadically), continents can rise and can fall during the journeys of their tectonic plates, and the ocean’s collective basin has fluctuated in size, as water was hydrated into rocks, and also falling when and rising again as they fragmented. Generally, when , the continental shelves lost their marine life, and , anoxic conditions often accompanied them. There is evidence that the ozone layer has been periodically damaged, which stressed all plants and animals that the Sun directly shined on. The positions of the continents, both in relation to each other and their proximity to the equator or poles, can have dramatic effects, including impacts on global climate. Global climate changes and moving continents can turn rainforests into deserts and vice versa.

This relates on how we see the world and see if it is reflected on them.

The USA’s Civil War was not only a watershed event in American history, but it also became a pivotal event in world history. It marked the transition from a largely rural nation, , to quickly becoming an industrial juggernaut that Earth had never before witnessed, with consequences both salubrious and catastrophic. The final chapters of the USA's imperial history have yet to be written. With the Civil War, the . What I call phase two of the Industrial Revolution began, and the rise of oil and electricity dramatically transformed industrial civilization.

I do think Canadians can be stewards of the planet by solving our own problems.


Earth Day: Ten facts that prove our planet is dying a …

There are too many scientific disciplines that state that the earth is more than 10,000 years old. Astronomy, genetics, linguistics, geology, plate tectonics, and archeology all say it is a lot older. The probable figure is about 4 billion years for planet Earth, and roughly 3 billion for life itself. We base our conclusions on appearances and scientific observations. The weight of evidence from all these disciplines is too much for me to dismiss. I do not find at all credible the assertions that the earth is only 10,000 years old and all the natural processes occurred within that time. (Bishop Ussher calculated 6,000 years old, and the Flood at 2348 BC.)

Actually, we’re about there already. Since 1980, the planet has experienced a 50-fold increase in the number of places experiencing dangerous or extreme heat; a bigger increase is to come. The five warmest summers in Europe since 1500 have all occurred since 2002, and soon, the IPCC warns, simply being outdoors that time of year will be unhealthy for much of the globe. Even if we meet the Paris goals of two degrees warming, cities like Karachi and Kolkata will become close to uninhabitable, annually encountering deadly heat waves like those that crippled them in 2015. At four degrees, the deadly European heat wave of 2003, which killed as many as 2,000 people a day, will be a normal summer. At six, according to an assessment focused only on effects within the U.S. from the National Oceanic and Atmospheric Administration, summer labor of any kind would become impossible in the lower Mississippi Valley, and everybody in the country east of the Rockies would be under more heat stress than anyone, anywhere, in the world today. As Joseph Romm has put it in his authoritative primer , heat stress in New York City would exceed that of present-day Bahrain, one of the planet’s hottest spots, and the temperature in Bahrain “would induce hyperthermia in even sleeping humans.” The high-end IPCC estimate, remember, is two degrees warmer still. By the end of the century, the World Bank has estimated, the coolest months in tropical South America, Africa, and the Pacific are likely to be warmer than the warmest months at the end of the 20th century. Air-conditioning can help but will ultimately only add to the carbon problem; plus, the climate-controlled malls of the Arab emirates aside, it is not remotely plausible to wholesale air-condition all the hottest parts of the world, many of them also the poorest. And indeed, the crisis will be most dramatic across the Middle East and Persian Gulf, where in 2015 the heat index registered temperatures as high as 163 degrees Fahrenheit. As soon as several decades from now, the hajj will become physically impossible for the 2 million Muslims who make the pilgrimage each year.

The Pinta eventually rejoined the Niña, with its captain’s gold quest profitably concluded. The captain claimed that he was innocently separated from the other ships, which may have been true. Columbus felt that the explanation was a lie, but could do nothing about it, so he did not punish the Pinta’s captain. On January 16, 1493, the ships were sailing back across the Atlantic, soon after they murdered two natives while trading on January 13th. Columbus described those murdered natives and their people as “evil, and I believe they are from the island of Caribe, and that they eat men.” That characterized the attitude that prevailed during the second voyage and beyond. If the natives were friendly and welcoming, they were the gentle Taino. If they were less than welcoming or were unfortunate enough to be murdered by the Spaniards, they were cannibalistic savages that deserved whatever fate that the Spaniards inflicted on them.
