"He walked frequently in forests and natural reserves", so he touched grass regularly but still did himself in, literally killed himself in a park which means he wanted the public to find his body in a public space and then wonder why he did it:
Teenager took his own life after ‘losing hope over climate change’

A 19-year-old Greenpeace activist took his own life after “losing hope” over the future of the environment, his family have said.
Theo Khelfoune Ferreras, a film student from Walthamstow, north London, was found dead in Brighton's Wild Park on March 29.
His sister, Lisa Khelfoune, 18, revealed that Theo, who worked as a fundraiser for Greenpeace, grew increasingly despondent about his efforts to tackle climate change.
His is thought to be one of the first deaths linked by loved ones to concern over climate change.
The worsening climate crisis combined with the Covid-19 pandemic and the pressures of being a university student left him feeling anxious, his sister said.
“He wanted to contribute to a change in society and tried to live according to his values,” she told the Brighton Argus.
“He wore mainly second-hand clothes, rode his bike everywhere, he walked frequently in forests and natural reserves.
“I think he had a complete feeling of helplessness. Theo felt like what he was doing was futile and he lost hope in the future and this devastatingly affected his mental health.”
