I just had the once in a lifetime opportunity to see David Suzuki talk at one of his stops in his â€œIf YOU were Prime Minister…â€? tour in my home city. David Suzuki is a very passionate and inspiring speaker; he spoke of humanityâ€™s origins and how we have lived on this planet for the last 150,000 years and what our current effects are on the planet. He went over the current issues surrounding global warming as well as some of the data and research backing it up. He discussed a very important study by a prominent economist which presented evidence that the cost to the world of preventing global warming would only be 1% of our GDP, but the cost of doing nothing would be more than world war 1 and 2 combined and it would put us into a depression like weâ€™ve never seen in human history.
