Definitive outline of our work

At meeting of 30 April, we´ve decided to include a new point in our work: "Causes and consequences of dissapearance of species".
The reason is that we only had four points for the presentation and we are five people in the gruop.
We were thinking about dividing a point to two people but, finally, we´ve added a new point.
This is the definitive outline:
1."Introduction"
2."Causes and consequences of dissapearance of species"
3."Most endangered species in the world"
4."Endangered species in our region: Extremadura"
5."Measures to prevent the disappearance of endangered species"
