Ladies and gentlemen,

 

   “We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity”. So said E. O. Wilson.

   Today we celebrate the International Day for Biological Diversity, a day dedicated to raising awareness about the importance of preserving the diversity of life on Earth.

   Biodiversity is the variety of species, ecosystems and genetic diversity, and maintains the dedicate balance of our planet. Nature provides us food, medicine, clean air and water. Yet, we seem to be destroying everything arround us, jeopardizing natural resources.

   According to the United Nations, one million species are at risk of extinction, many whithin our lifetimes. This loss of biodiversity has far-reaching consequences for Earth.

   On this International Day, let us dedicate ourselves to the task of protecting and preserving the rich tapestry of life on our planet, for there is still time.

   Thank you.

Speech “Biological Diversity Day”

Hello everyone,

Today, 22^nd of May, we are promoting biological diversity, in order to draw attention to how our society is impacting this diversity.

But first, what is Biodiversity? Well, it is the variety of living species in the world. Flora and Fauna. Without it, living in this planet wouldn’t be possible, despite all our technological advances. But how is biodiversity connected to our current actions?

It happens that nowadays humans are constantly destroying habitats, leading to an extinction of many species. Deforestation, cattle activity, even the greenhouse gases emissions are related to this problem. We are changing the balance of nature and decreasing the number of species. We are devastating nature in order to live a “better” life. But how long it will be possible for us to live like that?

We now need solutions that tackle the climate and biodiversity crisis. We need to build a shared future for all life. More than that, we need society to build a better future.

Thank you.

Ladies and Gentlemen,

 

Today, we gather to talk about a current and truly influential issue.

As a matter of concern, we should warn you about the impact of the Ozone Layer in our lives. Because of it we need you not just to hear, but to listen!

The ozone layer, a delicate layer of gas that protects our planet from harmful UV rays, has been under threat for decades due to the release of harmful chemicals such as chlorofluorocarbons (CFCs).

The Montreal Protocol, signed in 1987, called for the reduction of CFC production and eventually led to the complete elimination of these chemicals. As a result, the ozone layer has slowly started to recover, and we can expect it to return to its pre-1980 levels in the coming decades.

But our work is far from done. New threats to the ozone layer, such as the release of hydrofluorocarbons (HFCs), continue to emerge and must be addressed if we are to protect this vital shield. We need to act. And we need to do it NOW!

The Ozone layer is just like our mother Earth. It protects us from harm, and we should protect it from suffering. Play your part!

A message to the planet

     Imagine if you suddenly stop existing. Do you know how many species there are in the world? There are about 8.7 million species. However, 87 thousand go extinct per year. This rate of extinction would be similar to the death of all inhabitants of New Zealand by 2050.

     You probably think that this will not affect you, right? Well, you are wrong, mate. If the planet is affected, so are we. The planet is an ecosystem and so every single form of life is connected. For example, if a planet vanished, that would cause a chain reaction regarding the death of its consumers which includes ourselves. If you think about it, the world is like a big machine where everyone works towards the same goal. This shows how attached we all are.

     Pollution. Deforestation. Wildfires. Overhunting. Greenhouse gas emissions. All of this have the same origin: US. We are the problem, we are killing our home and thousands of innocent species.

     We have to change our behavior to save New Zealand and the entire world. To save all the Wildlife.  It’s totally in our hands. We are the problem and the solution. We have to save the same planet we hurt.

Remember, it´s all in your hands!
