Lorde "peaced out" on social media because she felt like she was "losing her free will".
The singer-songwriter decided to step back from the likes of Twitter and Instagram because she felt "massive amounts of stress" about the planet, racism and police brutality.
Speaking to Cazzie David for US-based Interview magazine about social media, she said: "Part of what made me peace out on social media, apart from feeling like I was losing my free will, was the massive amounts of stress I was feeling about our planet, about systemic racism, and about police brutality in this country."
And the 24-year-old singer loves how it's "cool" to care about the environment in New Zealand.
Asked if she feels less like the world is ending when she's in New Zealand, she added: "That's probably not realistic, but I feel that more is being done. I feel like our government is more proactive about acknowledging that we are living in a rapidly changing climate and legislation has to reflect that.
