Al Gore gave an inspiring talk last night at Harvard University titled “Healthy Planet, Healthy People” in honor of the late Dr. Paul R. Epstein, the brilliant scientist who shared the Nobel Peace prize with him in 2007.

Gore started the night by acknowledging Dr. Epstein’s work in connecting the dots between climate change and its impact on global human health.

Warming temperatures will allow disease carrying mosquitoes to spread out of the tropics, bringing malaria, dengue fever, and other currently tropical diseases to higher latitudes. “Global warming will also prolong mosquitoes reproductive and life cycles, and enable deadly viruses to survive in places that were too hostile for them before” Gore explained.

Gore also mentioned the connection between the uprising of diseases like cholera and global warming. “Communities have learned to deal with cholera by investing in infrastructure and building better sewer systems. The last thing they would have done is turn their streets into an open sewer. But that is exactly what we are doing to our atmosphere. We are using it as an open dumping ground, dumping over 35 billion metric tones of carbon per year”.

Gore quoted James Hansen, head of the NASA Goddard Institute to illustrate the severity of the situation “the amount of extra heat being trapped in our atmosphere is like exploding 400,000 Hiroshima atomic bombs per day 365 days per year, that is insane”.

He continued by explaining how the weather patterns are also being severely disrupted by global warming. “We will have more floods, stronger hurricanes, and more intense droughts in the upcoming years. Communities all around the world are experiencing one in a hundred, one in a thousand events every two or three years. Extreme weather will become the new normal.”

The audience broke into laughter when Gore mentioned that “When Inconvenient truth came out I repeatedly heard from my detractors that I was exaggerating when I talked about water flooding the World Trade Center memorial site. After Sandy, I don’t get that anymore”.

Gore explained how democracy and capitalism, the two pillars supporting the weight of our society have been degraded over time and turned into a corrupted and intertwined mess.

“Our democracy has been hacked, our operating system has been turned into something very different our founders intended. What our founders gave us was amazing, and I’ve watched it degrade over time.” Gore said.

Gore also said that “our elected representatives today are not worried about their constituents, they spend their time begging for money, it’s a race of who can put more ads on TV. This deeply affects the way they think and make decisions.”

Even if corruption is evident, Gore remains optimistic in our democratic system. “I am hopeful because of the internet. Not today, not tomorrow but soon the internet will replace TV and people will have an open space for debate and conversation, internet is the public square for democracy”.

Gore also explained that our economic system needs to be redefined. One of the main problems our current system faces is our definition of growth. “The definition we are using for growth is literally insane” Gore said.

Gore argued that GDP, the main tool for measuring a country’s economy is terribly flawed.

Simon Kuznets, the economist who first developed GDP in 1934 warned that it should not be used to measure a country’s wealth. But of course, nobody listened.

Since GDP was implemented in 1937, almost 95% of the US income goes to the top 1% of the country.

Gore, like Kuznets and many others believe that GDP fails to take into account major aspects of a country’s economy, such as externalities, depreciation of resources, positive externalities or distribution of income.

Costs related to pollution or environmental degradation are not accounted for (externalities), and contributions to science, mental health or arts (positive externalities) are also ignored in this economic model.

“Our GDP tells us, hey we are doing great, the US is just fine, but in reality we are not. Only the top 1% is doing well. We must be more accurate, or this economic model will drive us over the edge of the cliff.” Gore said.

But despite all this, Al Gore remains hopeful. “I am optimistic because President Obama in his acceptance speech addressed Global warming in an urgent manner, more than any other president before him. Obama now has no choice but to address global warming and act. And I know he welcomes this challenge”.

Al Gore is hopeful that renewable energies will pick up soon as the cost reduction and increased implementation will make them more accessible. He also recommends putting a price on carbon and regulating CO2 emissions from power plants.

Gore ended his talk praising young people’s passion and desire for change. “Young people that don’t succumb to the temptation of being cynical, and are passionate about what they do is what gives me hope for the future”.
