Study: humans may cause mass extinction in oceans

A team of scientists, in a groundbreaking analysis of data from hundreds of sources, has concluded that humans are on the verge of causing unprecedented damage to the oceans and the animals living in them.
“We may be sitting on a precipice of a major extinction event,” said Douglas J. McCauley, an ecologist at the University of California, Santa Barbara, and an author of the new research, which was published on Thursday in the journal Science.
But there is still time to avert catastrophe, Dr. McCauley and his colleagues also found. Compared with the continents, the oceans are mostly intact, still wild enough to bounce back to ecological health.
“We’re lucky in many ways,” said Malin L. Pinsky, a marine biologist at Rutgers University and another author of the new report. “The impacts are accelerating, but they’re not so bad we can’t reverse them.”
Scientific assessments of the oceans’ health are dogged by uncertainty: It’s much harder for researchers to judge the well-being of a species living underwater, over thousands of miles, than to track the health of a species on land. And changes that scientists observe in particular ocean ecosystems may not reflect trends across the planet.
The complexity of our planet points to a deliberate Designer who not only created our universe, but sustains it today

The Earth…its size is perfect. The Earth’s size and corresponding gravity holds a thin layer of mostly nitrogen and oxygen gases, only extending about 50 miles above the Earth’s surface. If Earth were smaller, an atmosphere would be impossible, like the planet Mercury. If Earth were larger, its atmosphere would contain free hydrogen, like Jupiter.3 Earth is the only known planet equipped with an atmosphere of the right mixture of gases to sustain plant, animal and human life.
Documentary: Inside the Garbage of the World (Video)
We’re living on a beautiful planet and as a human race we’ve been here for thousands of years. Our planet didn’t need to be protected; life was flourishing on its own, with its own agenda. However for the past 100 years we’ve made a tremendous impact with our footprint due to the growth of world population and the industrialization of our everyday life. Economy, profit and capitalization became more important than respecting our planet and an ancient knowledge to advance a new way of life.

Documentary: Planet Ocean (Video)
An elegantly filmed documentary, Planet Ocean takes us on a beautiful adventure into the strangest domains of our planet – the oceans. Directed by Yann Arthus-Bertrand – the noted environmentalist, journalist, and photographer, whose previous environmental documentary work includes the Home Project – this award-winning documentary pivots around the relationship between the Earth’s oceans and the entire planet’s ecosystem.

Satan the Outcast – From the 7th Heaven to Hell (Video)
Abdullah Ibn Omar, said that the Jinn, the descendants of Jaann, had existed for about two thousand years before Adam. They made mischief and shed blood, therefore God sent army of Angels who expelled them to remote islands. When the angels said, “while we glorify You with praises and thanks (Exalted be You above all that they associate with You as partners) and sanctify You.” means we always worship You and none of us ever disobey You. We worship You day and night. And when God said to the angels, “He said, “I know that which you do not know.” means God told them that He had the best of knowledge about the purpose of their creation which they had no knowledge of it. And He said, “I am setting on the earth a vicegerent.”

Found in all oceans of the world, orcas are most common in the Arctic and Antarctic and are often spotted off the west coast of the United States and Canada. Orcas are found in both coastal waters and open ocean. Orca’s can live for an average of 50 to 80 years. The brain of a killer whale can weigh up to as much as 15 pounds (7 kg). That’s about five times heavier than the average human’s, making it one of the biggest brains on the planet.
LIGHTNING ABOVE LAKE MICHIGAN (IMAGE)
- Lightning is a powerful burst of electricity that happens very quickly during a thunderstorm.
- Lightning is caused by an electrical charge in the atmosphere that is unbalanced.
-
The movement of rain and ice inside a thundercloud creates an electrical charge, with the negative charge (electrons) forming at the bottom of the cloud and the positive charge (protons) forming at the top.
-
Lightning can occur inside clouds, between clouds and from clouds to the ground.
-
Thousands of people are struck by lightning every year.
-
Most lightning occurs over land rather than oceans, with around 70% of it occurring in the Tropics.
-
There are bolts of lightning striking somewhere on Earth every second.
-
Lightning strikes usually last around 1 or 2 microseconds.
-
The average temperature of lightning is around 20000 °C (36000 °F).
- Astraphobia is the fear of thunder and lightning.
