First here are a few direct quotes from the UN's Agenda 21 (granted it's not the WEF but its all the same people at the top).
"Policies should be designed to address the consequences of population growth built into population momentum, while at the same time incorporating measures to bring about demographic transition."
"5.31. National population policy goals and programmes that are consistent with national environment and development plans for sustainability and in keeping with the freedom, dignity and personally held values of individuals should be established and implemented."
Second, I take some issue with the APNews article because they gloss over the main point... Jane Goodall herself does believe in population reduction. This is nothing new, she has been saying this for decades. For example she is a member of the Population Matters Group in the UK (formerly Optimum Population Trust). This group and many like it are actively advocating for governments to implement policies that will put earth's human population into decline for the express purpose of climate change. So I will defend my use of that clip because it makes the point I was trying to make. Important people in power desire to reduce the population to reduce carbon emissions.
To expand my point here are other Jane Goodall quotes from the Population Matters website:
“Educating and empowering women and girls and providing family planning information enables more people to choose the size of their families. These are the kind of positive actions governments can take, and must take if we’re to address the biodiversity loss we’re facing.”
“It’s our population growth that underlies just about every single one of the problems that we’ve inflicted on the planet. If there were just a few of us, then the nasty things we do wouldn’t really matter and Mother Nature would take care of it — but there are so many of us.”
“This organisation, Population Matters, is so very important, because this is one of the most important issues that we face today. We can’t go on like this, we can’t push human population growth under the carpet. It’s been shown all around the world that as women’s education improves, family size tends to drop. I would encourage every single conservation organisation, every single government organisation, to consider the absurdity of unlimited economic development on a planet with finite natural resources.”
“The climate crisis that now threatens life on Earth as we know it results from a combination of different human activities, including the pollution of land, air and water, our reckless burning of fossil fuels, the destruction of forests, extreme poverty, and the unsustainable life styles of so many of us. And all of this is impacted by the relentless growth of human populations and their livestock. Educating and empowering women and girls and providing family planning information enables more people to choose the size of their families. And choosing to have fewer children is one of the most important choices we can make.”
As you can see she is quite outspoken on this topic and has been for a long time. Long enough for the people at the WEF to invite her her to speak knowing her position.
