Most likely, mass extinction isn't something you want to think about every day. But eventually there may come a time when there won't be a chance to do something about it if we don't think about it.

Due to population growth, climate change, pollution, and other problems, scientists predict that we're heading down a path towards doom, with human extinction predicted by 2100.

French star Mélanie Laurent and environmental rights activist Cyril Dion took on this premise in their documentary Tomorrow (Demain) to how people around the world are taking action to help us avoid an apocalyptic fate.

The filmmaking duo visited 10 countries to spotlight everyone from teachers and urban farmers to city planners and activists to show what they are doing to address issues like global warming, food security, agriculture, ecology, and clean energy.

Interviewees include Indian writer and activist Vandana Shiva, Danish architect and urbanist Jan Gehl, permaculture teacher Rob Hopkins, and Detroit Black Community Food Security Network founder Malik Yakini.

The film will screen in Vancouver at the Rio Theatre (1660 East Broadway) at 3:30 p.m. on Saturday for Earth Day (April 22). Tickets are $10 in advance, or $12 at the door.

B.C. Green Party candidate for Vancouver–Mount Pleasant Jerry Kroll present a talk after the film.

Next week, Reel Causes will hold Climate Revolution, an event in honour of Earth Day and in support of the Vancouver-based environmental law non-profit Ecojustice.

The event will offer a screening of the documentary How to Let Go of the World and Love All the Things That Climate Can't Change.

In this film, Gasland director Josh Fox traveled to 12 countries to examine and reveal the destruction that climate change has wrought, and what people are doing to try and counter the impact. He captures everything from solar power in impoverished communities to health problems caused by perpetual smog in China.

It'll be held at 6:30 p.m. on April 27 at SFU Woodward's (149 West Hastings Street). Tickets are $5 (plus $10 for membership).

A post-screening panel will include Ecojustice lawyer Larry Wruck and four local changemakers. 

Information about the event is available at the Reel Causes website.
