Posted by Allen Macartney in The RCGS on Saturday, June 30, 2012

The day before leaving on my 1,500-km solo canoe trip, Grant Zazula, Yukon's paleontologist, gave me a lesson on how to toss a deadly atlatl.

What is an atlatl?

It's a hunting weapon that native hunters used to extend the kill zone when out stalking game.

A regular spear can only reach a limited distance, but by using an atlatl (a length of notched wood helps propel the spear) you can extend your range and force. Native hunters used these until the bow and arrow were discovered, but some ...

The air inside a home can be up to 1000 times more polluted than the air outdoors according to Adria Vasil, author of Ecoholic Home. 

Ironically, household cleaning products are to blame. Conventional cleaners—degreasers, disinfectants and even air fresheners—release chemicals that contaminate the air we breathe and affect our immune systems.

So how can we mop our floors and wipe our counters without destroying our germ-fighting capabilities?

After reading this you may want to buy stock in - or stock up on - Kleenex. Ragweed pollen is lingering in the air for more than a month than it did in 1995, says a study published last month in the Proceedings of the National Academy of Sciences.
