Children and young people today are growing up in an increasingly urban, technical, virtual and ecologically precarious world, leaving many feel disconnected from nature yet anxious about its degradation at the same time. Two distinct bodies of knowledge -- namely youth human-nature relationships and youth eco-anxiety -- are concerned with the former and the latter respectively. Through a narrative literature review, we bring these fields together and explore their interaction. We demonstrate that the dominant responses of facilitating nature exposure and encouraging environmental action risk counteracting each other and ultimately fail to address the root cause of children and young people's experiences. We further show that emerging responses in both fields are overcoming these limitations by turning towards a reimagination of humanity's relationship with nature, providing a holistic way forward. We conclude by discussing barriers restricting the expansion of such approaches and opportunities for future research to contribute to dismantling these barriers.
