About Us

Transition Earth advocates for a thriving world through supporting the empowerment of people by linking population, health and environment.

 

We engage with people - especially global youth - on issues related to population growth, such as sexual and reproductive rights, climate change and overconsumption of resources. We do this through blogs, social media, webinars, and public events.

 

Transition Earth is a project of Earth Island Institute.

Earth Island Institute, a 501(c)(3) organization, provides fiscal sponsorship, resources, training, technical assistance, and peer relationships to environmental activists looking for an organizational home and institutional leverage for their work. Becoming a fiscally sponsored project is a strategic decision Transition Earth made in order to increase our effectiveness, organizational durability, and greater capacity to do our work. Earth Island leverages the power of a network of diverse projects, the invaluable knowledge and influence of renowned leaders in the environmental movement, and the track record of a 35-year old organization and experienced staff. They are home to projects on the forefront of the environmental movement utilizing strategies that are responsive to the social, economic, and political realities of our time.

Karen Gaia Pitts

Karen Gaia Pitts has lived in California most of her life. Her professional career was in information technology and web development.

She started traveling the world in 1995, with a trip to China, where she saw that every piece of land, except in the mountains, was in use by the population. Karen has traveled to most of Asia, parts of Africa, and Central and South America. She found her travels were most enjoyable in rural areas and everywhere she went she studied sustainability, women’s empowerment, family planning, and girls education.

In 1997 she started a website called World Population Awareness.

In 2016 Karen’s partner went to Tanzania and visited a former student he had once sponsored, who lived in a remote Maasai village. There, a woman stood up in front the assembly of villagers, and asked for several things, including education and family planning. Upon hearing that, Karen got hooked into supporting the Maasai project and helping them meet their many challenges.
