Subject: A lake that reveals our impact
Interesting article about a lake whose sediments tell a story...and not a pretty one.

In just seven decades, the scientists say, humans have brought about greater changes than they did in more than seven millennia. Never in Earth's history has the world changed this much, this fast. Never has a single species had the capacity to wreak so much damage ' or the chance to prevent so much harm.

Simpletons say 'the earth's climate has always been changing'. Yes, true. But it's the pace of change now that is alarming.
