"According to the UNEP study, an annual investment of $45 billion to biodiversity conservation worldwide could safeguard about $5 trillion in ecosystem services – a benefit to cost ratio of 100 to 1." -Bill Jones "Economic Value of Lake Ecosystem Services"
I was doing some research for my socioeconomic and lake ecosystem services project the other day when I came across this 2010 article by Bill Jones. It's a great (and short!) read on the economic value of ecosystem services that is absolutely worth checking out if you're interested in the subject. The above quote is my favorite from the article. And, just for kicks, below is a link to an infographic of exactly how much one trillion dollars is (now keep in mind, above he's talking about five trillion dollars). Enjoy!
