In this program after the questions they talked about the many words and phrases that they learnt in their program.

Feifei and Rob, discused about the expression "dead as a dodo" they make reference about the extincted bird, and can be used this expression to describe something that was completely dead or no longer working.

they said that some experts were predicting a global 'extinction crisis'. So it's an extremely urgent stop this situation because this problem was increasing. They took a references with Mary Rice from the Environmental Investigations Agency and David Shukman, BBC correspondent. She said that the function how some people organised this illegal trade like the people never been intercepted because they taken many precautions, and he said that exist many things for made like having an international agreement clearly together a police co-operation and political will to halt the killing.

I really love this program because it open a vision about this big problem, because the people threaten with life of the most vulnerable. This situations make me think that this world is very sad, because the people kill animals for its skins, horn, etc, or for enjoyment, instead of made it for save them life or because they need something to eat.

This situation wasn't unusual because since that the humans made weapons that they killed any thing that they see and thay can killed, inclusive other people, always the most vulnerable.
