Called by some the Blue Eye of Siberia and by others the Sacred Sea, Lake Baikal, at more than 5,000 feet ( 1,620 meters ), is the world’s deepest lake. The lake has many other interesting features also. For example, more than 330 rivers flow in but only the Angara flows out.

Even the potential for oil-related environmental disaster along the Eastern Siberia–Pacific Ocean pipeline was enough to get that project moved farther away from one one of UNESCO's world heritage objects.

What do you do when Mother Nature herself starts leaking the oil?

Is something better than nothing while society adjusts to the impact of pollution and climate change? Or is a "band-aid" approach just making people feel better and wasting time? It depends on which environmental group you ask.

The Royal Society for the Protection of Birds issued a withering attack on the British government, calling its policy on tackling climate change too myopic to be effective after the publication of another Westminster report detailing additional restrictions that should be in place.

The report, by the Joint Scrutiny Committee, said aviation must be included in climate change planning.

Every 62 million years there is a mass extinction on Earth. No one is sure why but, since the solar motion through the Milky Way has been computed for the past 600 million years, we know it is too long a cycle for it to be a product of our solar system. A new paper theorizes this is because the earth begins to ... wobble ... due to solar oscillations and that wobbling happens on a predictable timetable.

They call it galactic shock due to cosmic ray modulation and its presence at those times impacts biological diversity - that means extinction and origination. The physicists, Mikhail V. Medvedev and Adrian L. Melott of the University of Kansas, say this has happened for the last half billion years. How much impact? As much as 10% of life on earth.

Why a wobble?

A recent UN study, Livestock's Long Shadow, basically says you can help the environment more by driving than walking.

A long-held belief in theories of human behavior is that people want to feel good and avoid feeling bad.

Nothing in that principle explains why people enjoy horror movies or, additionally, why they pay for the privilege of being scared.

Investigators generally use one of two theories to explain why people like horror movies:

1. It's excitement, not fear. People aren't actually afraid, they get a surge from the action and suspense.

2. Terror now brings euphoria later. Think you had a bad day at the office? Imagine being chased by zombies. It always feels better to know someone else is being chased by zombies.
