[00:08] From our homes to our vehicles, nearly everything we possess holds some kind of value, be it monetary or sentimental. We take pride in making sure they last. But do we hold the same appreciation for nature's services that sustain us here on Earth?

[00:24] The fish we take from our waterways, the timber we use to build our homes, the purification of the air we breathe and the water we drink, and the pollination of crops and natural vegetation are just a few examples of the services our planet's ecosystems provide.

[00:39] Because we have long taken for granted Earth's most fundamental life support services their value often goes unappreciated.

[00:47] Imagine that you were planning to live on the moon. Which species from Earth would you need to take with you to sustain human life? Which ones are crucial for food, drink and air, and what do those species need to survive?

[01:00] No one knows exactly which species are needed to sustain human life. Many of nature's services were developed by billions of years of evolution.

[01:09] As we alter our landscape for the betterment of society, we must ask whether current benefits draw down nature's capital leaving an impoverished future, and whether benefits for some come at the expense of others.

[01:21] Each of us has a responsibility to preserve Earth's life support systems for ourselves, as well as for our children and grandchildren.
