I hope you don't mind my comments here:

Back in 1987 when the Montreal Protocol was ready for international signatures, scientists were mainly concerned with the harmful effect of UV radiations on human and other life forms on the planet. The control and banning of ozone depletion substances (ODS) had little to do with Global Warming then (now called Climate Change).

Climate Change measures agreed at the 1992 Rio Convention and subsequent Conferences of the Parties (COP) annual meetings will only protect the ozone layer from the harmful effect of some but not all ODS. The Montreal Protocol is still needed to manage the risk posed by those ODS that are not Green House Gases (GHGs).

Haricot thank you for your comment on my blogger.
Yes, we must always be open-hearted by environmental causes, all that nature gives us we can not dim the fault of men ...
The Discussion of 1992 and 2002 were important but currently there seems to be backsliding on environmental diplomacy presssionada by environmental economics. The negociaçõessão always marked by resistance to the limits set for various forms of pollution effects with local, regional or Global ...

Manuela:

It is always good to find someone who shares the same passion about our environmental. You are right: We must not take Mother Nature for granted.

I agree with you that there has been backsliding in environmental protection at the local, regional and global levels. I hope people understand that Sustainable Development is like a 3-legged stool. Its equilibrium is dependent on:
* health/environment,
* economic development
* social development

Too much emphasis on economic development without due regard for health/environment and social wellness will send everything crashing down sooner or later.

I too enjoy reading your blog (I love pictures of those colourful birds). Let's keep in touch !!
