How the Early Pilgrims Celebrated Thanksgiving - 0 views

  • t is a basic notion that during the 1600's, accurately in the year 1621, the English settlers and the Wampanoag Indians got together and shared a fantastic fall harvest feast to celebrate the bounty from the rich earth. Today this celebratory feast is acknowledged to be one of the first Thanksgiving festivities in the early days of the colonies. While that long ago feast is supposed by a lot of people to be the first Thanksgiving celebration, it was, in fact, part of a long existing custom of celebrating the seasonal harvest and giving thanks for a good bounty of crops that would last through the long hard winter. Many Native American tribes of what would be named America, including the Pueblo, Cherokee, Shawnee, Huron, Creek, Blackfoot and so many others would hold huge harvest festivals, consisting in ceremonial dances, races, games and other cheerful celebrations of gratefulness hundreds of years before the European peoples arrived. If you are like me, you are surely wondering the kind of meals served at the harvest feast. Historians, as usual, are not one hundred percent sure regarding it; however they are sure that pilgrims weren't eating pumpkin pies nor building castle towers with mashed potatoes. However, it is easy to think that the list of meat available during this period of time should surely include venison as well as several types wild poultry such as duck, goose as well as wild turkey. While there are hundreds of manuscripts describing such feast, the most detailed description of this celebration of late harvest date of 1621 and was written by a man called Edward Winslow. It is from his manuscript called "A Journal of the Pilgrims at Plymouth" that historians have gleaned the greatest part of information about this first Thanksgiving celebration:
  • Although the first Thanksgiving dinners were not concentrated on the turkey; today's usual meal primarily focuses around this animal. During the 17th century, vegetables were not as important as of today, so the meal of this period of time included a lot of different meats. The many types of vegetables we take for granted today were not available to the colonists. Freezing methods did not exist; which means that the vegetable consumption was based on seasonal harvests. Because the colonists and Wampanoag tribe had no refrigeration in the 1600s, they dried a lot of their foods to preserve them. They would dry corn, wild boar hams, fish, venison, and many wild herbs.

  • Fewer people have died from bat rabies during the past 40 years than have died from dog bites or bee stings in a single year.
  • Although the bat is not blind, its eyes are best adapted to seeing in the dark, and see in only black-and-white.
  • The thumbs of the forefoot are small, equipped with sharp claws and not connected to the membrane.
  • Bats are very shy creatures and like most wild animals, avoid contact with humans while going about their business of eating, reproducing and avoiding predators.
  • When a bat returns to its roost for its upside-down sleep, it will spend as much as 30 minutes cleaning itself before settling down to sleep.
  • Some species of bats prefer to live alone in trees.
  • Nearly all bats that live in the United States feed on insects.

Coral feefs-Sunscreen - 0 views

  • n experiments, the cream-based ultra-violet (UV) filters -- used to protect skin from the harmful effects of sun exposure -- caused bleaching of coral reefs even in small quantities, the study found.
  • But some 60 percent of these reef systems are threatened by a deadly combination of climate change, industrial pollution and excess UV radiation.
  • The new study, published in U.S. journal Environmental Health Perspectives, has now added sun screens to the list of damaging agents, and estimates that up to 10 percent of the world's reefs are at risk of sunscreen-induced coral bleaching.

Ink & Mess: Starving Dog as Art - Gallery confirms exhibition as hoax - 0 views

  • Back in October 2007 Costa Rican artist Guillermo 'Habacuc' Vargas "paid some children to chase and catch a stray dog, after which he chained up the poor animal in a gallery, telling the viewing public not to feed or water it". Allegedly bowls of water and food were placed near the dog but alas, both items were just out of the its reach. On the wall above the dog the phrase "Eres Lo Que Lees" (translates as "You Are What You Read") was written in dog biscuits. The outcome of the exhibition was that "the dog slowly starved to death and eventually died in the gallery in view of everyone".

Oil Remains - 0 views

  • largest and most productive estuaries in North America.  
  • However, in 1993 the EVOS Trustee Council funded an additional survey that estimated 7 km of shoreline were still contaminated with subsurface oil.
  • Because a significant survey of Prince William Sound had not been conducted since 1993 and the cumulative extent of the remaining oil was unknown, concerns were generated by the public and scientific communities about the oil’s possible continuing effects on humans and fauna potentially exposed to the oil directly or indirectly.
  • ...14 more annotations...
  • Without an accurate assessment of the extent of the remaining oil, subsistence food-gatherers, consumers of commercial fish products from the area, and tourists have used mostly anecdotal evidence as the basis for economic decisions regarding resource utilization in the affected area.
  • Consequently, the Auke Bay Laboratory (ABL) with funding from the EVOS Trustee Council, took on the task of assessing the remaining oil along the shorelines of Prince William Sound during the summer of 2001
  • The primary objective of the project was to measure the amount of oil remaining in the intertidal zone of Prince William Sound.  Secondary objectives include determining the rate of decline of oil on these beaches, estimating the persistence of the remaining oil, and correlating the remaining oil with geomorphological features.
  • heavily and moderately oiled
  • The 2001 survey adopted a stratified random/adaptive sampling (SRAS) design. Two random pits were excavated to a depth of 0.5 m (1.6 feet) in every stratified block (0.5-m verticle drop in tide height) within a grid system established at each site. If subsurface oil was discovered in any of the randomly stratified origin pits, then additional adaptive pits were excavated above, below, to the right, and to the left of the origin pit until the extent of the oil patch was determined.
  • Buried or subsurface oil is of greater concern than surface oil.
  • Subsurface oil can remain dormant for many years before being dispersed and is more liquid, still toxic, and may become biologically available.
  • A disturbance event such as burrowing animals or a severe storm reworks the beach and can reintroduce unweathered oil into the water.
  • The toxic components of this type of surface oil are not as readily available to biota, although some softer forms do cause sheens in tide pools.
  • 1) Surface oil was determined to be not a good indicator of subsurface oil. 2) Twenty subsurface pits were classified as heavily oiled.  Oil saturated all of the interstitial spaces and was extremely repugnant. These “worst case” pits exhibited an oil mixture that resembled oil encountered in 1989 a few weeks after the spill - highly odiferous, lightly weathered, and very fluid. 3) Subsurface oil was also found at a lower tide height than expected (between 0 and 6 feet), in contrast to the surface oil, which was found mostly at the highest levels of the beach (Table 3).  This is significant, because the pits with the most oil were found low in the intertidal zone, closest to the zone of biological production, and indicate that our estimates are conservative at best.
  • The possibility of continuing low level chronic effects of the Exxon Valdez oil spill seem very real now, although measurable population effects would be very difficult to detect in wild populations.
  •  Sea otters and harlequin ducks fall into this category
  • such as sea otters, harlequin ducks, and their intertidal prey.
  • The last beach assessment was completed in September 2001. Supporting chemical analyses will be completed in fall 2002, and a final report with statistical analyses and conclusions will be completed by April 2002.

  • prey of wolves are large hoofed mammals, including deer, moose, elk, caribou, bison, musk-oxen, and mountain sheep. Beaver is eaten when available. In summer a variety of smaller foods, such as small rodents and berries, supplement the diet. Animals killed are usually young, old, or otherwise weaker members of their populations because they are easiest to capture.

Thoughts on Global Warming: Top 5 Worst Effects of Global Warming - 0 views

  • 1. Polar ice caps meltingThe ice caps melting is a four-pronged danger.First, it will raise sea levels. There is 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 230 feet. Luckily, that’s not going to happen. But sea levels will rise.Second, melting ice caps will screw up the global ecosystem. The ice caps are fresh water, and when they melt into the ocean, they make it less salty, or desalinize the ocean. The desalinization of the gulf current will screw up, to put it simply, the current. It will cool the area around north-east America and Western Europe. Luckily, that will slow some of the other effects of global warming in that area. But with the stream shutdown, the whole Atlantic ecosystem could be warped.Third, all the animals in the Arctic will be in danger because of a changing habitat.Fourth, global warming will accelerate with the ice caps gone. Ice caps are white, and reflect sunlight. Some of that sunlight is reflected back into space, further cooling Earth. If the ice caps are melted, only the dark-colored ocean will be there. Darker colors absorb sunlight, further warming the Earth.

  • After rodents, bats are the most numerous mammals on earth.
  • Males have a bright orange ruff and wings are black, which contrast with the tawny body fur.
  • African bats fall into two major categories large fruit bats and smaller, insect-eating bats, none of which attack people.
  • ...4 more annotations...
  • Bats are primarily found in forests and savannas. Colonies of bats roost together in tall trees.
  • In some parts of Africa straw-colored fruit bats are considered a delicacy. Elsewhere they are considered pests and killed to prevent the destruction of fruit crops. Studies, however, have shown that bats only eat very ripe and unmarketable fruit and may even help reduce fungi and fruit flies in commercial plantations. Bats are also slaughtered because of superstitions and the musky odors and noise emanating from their roosting places.
  • Bats, like most wild animals, will bite if handled, but if left alone they normally will avoid contact.
  • Bats are versatile. The insect-eating type is a natural pesticide. Bat excrement, called guano, is sold as fertilizer. And seed dispersal and pollination activities of certain bats help tropical forests survive.
