First time posting on this forum. I just recently started reading Ayn Rand, and as I consider myself an environmentalist, I wanted to hear some Objectivist views on the non-human parts of this planet we inhabit and our relationship with those parts. I read most of this thread and have some things I would like to bring up. First, please stop denying the reality of anthropogenic climate change. There is a broad scientific consensus. Please find me a few peer-reviewed articles from the last two years that support your position. Not Rush Limbaugh or Anthony Watts, but peer-reviewed articles from real scientific journals. As I mentioned, I'm new to Objectivism, but it appears that the central tenet is that objective truth is out there, and that “subjective truth” has been used to justify a whole variety of harmful and abusive actions. Members of the climate change denial movement seems to be so obviously in this latter camp, denying mountains of evidence in order to maintain a position that allows for them to continue behaving destructively, at the expense of fellow humans. As will all ecological destruction, those humans at the bottom of the economic ladder are hardest-hit. Poor people have the most direct relationship with and the greatest dependence on the natural world in order to survive. I live in Tanzania (in East Africa), and maize is a staple crop here. Maize is going to be one of the hardest-hit crops by rising temperatures; those little stringy bits that hang out of of fresh (un-husked) corn are what collect pollen and bring it to each individual grain under the husk. These strings (forgive me, I forget the term for them) are sensitive to temperature; too hot, and the strings dry up, fertilization doesn't happen, and the crop fails. It is predicted that East Africa is going to be among the parts of the world hardest-hit by climate change, largely due to increasingly common failed maize harvests. (source: “The World on the Edge,” which I'll just refer to as WotE when I cite it again, published by the Worldwatch Institute in 2011. Wonderful book, highly recommended.) So here's my question: do I have a right to emit as much greenhouse gas as I want, when those actions contribute to food insecurity in many places around the world? Do I have the right to fly around the world, have a huge house, drive a Hummer, or eat nothing but factory-farmed beef, when those actions contribute to famine in East Africa or rice farmers in coastal Bangladesh losing their paddies as the seas rise? A few of my libertarian friends have told me that humans have the freedom to do whatever the want, as long as they don't deprive other humans of that freedom. I can partially agree with that belief, but only if we expand that vision beyond a local context. Our actions have regional and global consequences. Unsustainable consumption of resources is misanthropic, ultimately depriving the poor and future generations of the ability to meet their basic needs. Studies (Wackernagel 2002, for example, cited in WotE) have shown that humanity has exceeded the natural carrying capacity of the planet. I am glad that Ed admitted earlier in this thread that we are part of nature; indeed, even with our technological arrogance we still depend on many of earth's natural processes for our survival. We harvest natural resources and use the natural world to absorb our wastes. A recent guess puts our factor of unsustainability of 1.5; we require the natural processes of 1.5 earths for long-term sustainability. Right now we're exhausting natural resources beyond the replenishment rate (including many aquifers (for example, unsustainable overpumping in India currently feeds 175 million people), soils, and forests) and creating wastes faster than their absorption rate (carbon dioxide is an easy example). Eventually this will catch up to us, and the human population will be forced down. How can we get to a sustainable human presence on this planet? It is possible (though difficult) to calculate what sustainable level of inputs and outputs would be. How much carbon dioxide we can emit, how much fresh water we can pump from aquifers, how much nitrogen we can extract from the air for fertilizer. The Worldwatch Institute has started doing this (check out “State of the World 2013: Is Sustainability Still Possible?” Another recommended read!). We could take those numbers, divide by 7 billion, and say each human is only allowed to consume what would be sustainable if we were to multiply that consumption by 7 billion. The logistics of this are extremely tricky, perhaps impossible, but let's just say it's possible for the purposes of this thought experiment. Each person gets 1000 “sustainability credits” that they can spend however they want. You have the freedom to do whatever you want, provided that freedom doesn't end up drowning Bangladeshis or starve Tanzanians. This seems totally in line with Objectivist thinking. What do you all think? Regarding the “intrinsic value” argument. I believe that all life has the right not just to exist, but to thrive, humans included. In the pursuit of happiness, why does one have to take into account the rights of other humans? Why can't I kill people and steal their property? Is it just because we're members of the same species? Why is that special? Why not respect the right to exist of other primates? We share 96% of our genome with them, after all. And then why not other mammals? Why not all life?
