Please read the article above. It discusses and refutes all the arguments by people who say we have lived through worse or are recycling etc
Some extracts from the article -
"cites a study from 2010 that looked at the impact of demographic change on global carbon emissions. It found that slowing population growth could eliminate one-fifth to one-quarter of all the carbon emissions that need to be cut by midcentury to avoid that potentially catastrophic tipping point."
"no amount of conservation gives you a pass. Oregon State University researchers have calculated the savings from all kinds of conservation measures: driving a hybrid, driving less, recycling, using energy-efficient appliances, windows and light bulbs.
For an American, the total metric tons of carbon dioxide saved by all of those measures over an entire lifetime of 80 years: 488. By contrast, the metric tons saved when a person chooses to have one fewer child: 9,441."
Another student asks: "What happens if that kid you decided not to have would have been the person who grew up and essentially cured this?"
Again, great question, says Rieder, but the answer is still no. First, the chances are slim. More to the point, he says, valuing children as a means to an end — be it to cure climate change or, say, provide soldiers for the state — is ethically problematic.
With all that's at stake, he says, we need to shift our cultural attitudes. "It's not the childless who must justify their lifestyle. It's the rest of us."
