Dropped jaws, and shocked gasps filled the room at Tuesday night’s San Francisco premiere of Death by Design by Sue Williams.

The sold out screening produced by the San Francisco Green Film Festival, as part of Bay Area Science Festival, was a rude awakening for many in the room.

Sue Williams' documentaries are an in-depth look into the past, present, and future.

In her most recent production, Death by Design, she does an in-depth investigation into the electronics and technology companies and the harmful environmental and health effects that come with them on a global scale.

We all love – and live on – our smartphones, tablets and laptops. 

A cascade of new devices pours endlessly into the market, promising ever better communication, non-stop entertainment and instant information.

But can tech be made sustainably?

I've always considered myself pretty green.

Film entries for next year’s San Francisco Green Film Festival are coming in from across the globe.

The Festival may be over but we're planning more screenings of some of your favorite films.

This week, Governor Brown signed historic legislation that will ban the use of single-use plastic bags in California, the first state in the USA to do so. Why is this important? Americans use 60,000 plastic bags every five minutes, disposable bags that they throw away without much thought. But where is "away"? Where do the bags and other plastics end up, and at what cost to the environment, marine life, and human health?
