2010 is the International Year of Biodiversity; world leaders failed to stem the decline of biodiversity

I chose that title because summarize the main problem in the ecosystem. It appeared in this news: “Carnivorous fish blamed for grebe's extinction in Madagascar” (http://www.guardian.co.uk/environment/2010/may/26/grebe-extinct-birds).

I feel so confused. I don’t know what I do when I read this kind of news about extinction, abuse animals and ecosystem problems. What I can understand is why we don’t anything significant for change the situation. I think is our responsibility to take care of the planet. We are humans, we guess we are the only animal thinking. However; we are the most destructive living being.

In this case, the problem is about the extinction of birds. If you read the title of article you know that a carnivorous fish is the blame. However; this fish didn’t use to live in this lake but humans introduced it there place so years ago.

I completely agree with the following: “world leaders failed to stem the decline of biodiversity. We cannot fail again." Humans have introduced a lot of animals where didn´t use to live, consequently; ecosystem has been changed by our actions. Besides, we can forget that contamination and global warming is our responsibility. We have to use the knowledge of the science for take care of the planet and we stop to damage it.
