Listen to an audio podcast from the USGS explaining the use of Light Detection and Ranging, or LiDAR. “USGS scientists use high-resolution LiDAR data to create virtual 3-D landscapes, similar to the wireframe worlds found in movies and video games. With these virtual surfaces, investigators can now manipulate, measure, model, calculate, and examine the landscape in a whole new way and discover things previously unseen.”

Home – human impact on the environment

From the web site:

We are living in exceptional times. Scientists tell us that we have 10 years to change the way we live, avert the depletion of natural resources and the catastrophic evolution of the Earth’s climate.

The stakes are high for us and our children. Everyone should take part in the effort, and HOME has been conceived to take a message of mobilization out to every human being.

For this purpose, HOME needs to be free. A patron, the PPR Group, made this possible. EuropaCorp, the distributor, also pledged not to make any profit because Home is a non-profit film.

HOME has been made for you : share it! And act for the planet.
