NILES — Chikaming Open Lands and Fernwood Botanical Garden will host an environmental film festival featuring two powerful films, “Death by Design” and “Five Seasons with Piet Oudolf.”

“Death by Design” will be presented at the Vickers Theatre in Three Oaks at 7 p.m. July 11. Consumers love — and live on — their smartphones, tablets, and laptops. A cascade of new devices pours endlessly into the market, promising even better communication, nonstop entertainment, and instant information. In an investigation that spans the globe, filmmaker Sue Williams investigates the underbelly of the electronics industry and reveals how even the smallest devices have deadly environmental and health costs.

“Five Seasons with Piet Oudolf” will be presented at the Vickers Theatre in Three Oaks at 7 p.m. July 25. An immersive and meditative documentary, “Five Seasons” reveals how the revolutionary landscape designer, Piet Oudolf, upends conventional notions of nature, public space and, ultimately, beauty itself.

Registration is required, as seating is limited for both screenings. Cost is $10 (Fernwood and COL Members $8) per movie or $15 (Fernwood and COL Members $12) for both movies.
