So far a lot of articles I have read about biodiversity and climate change, have been about the poles (mostly the Arctic) or about coral reefs and oceans and how they are being affected. If you have read my previous blog posts they summarize these topics and talk about how the slight change in the arctic will majority affect the food chain from the top to the very bottom (generalized single-celled organism, invertebrate, amphibians). Also how the acidification of the ocean is going to ruin the coral reefs of our ocean. If you haven’t read these blog posts yet, you should!

The newest article I have read, “A Little Climate Change Goes a Long Way in The Tropics, ” by, Susan Milius, is not about either of these zones, but one that has gone under the radar in recent publicity about climate change; The Tropics.

Little do we know that the slightest change in temperature in the tropics is going to do big damage to the animals that warm and cool with their surroundings. As there surroundings warm up their metabolism speeds up. Resulting in an all around increase in the pace of life in the tropics. While reading this article I asked myself why is that such a bad thing, as I read on, it explained.
access “Caiman Lizard is one animal that will adapt to increasing temperatures.”

If the environment around these animals heat up then the animals and organisms are going to increase the rate of their metabolism. With an increase in their metabolism they need an increase in the amount of food that they eat in order to turn it into energy. This article goes onto explain that it might result in starvation if the ecosystems can not keep up with the increase of the metabolisms.I personally have never thought about animals in the rainforest running out of food, this amazes me. It makes sense, with the increase of metabolism requiring more food and a decrease in food, animals really will face starvation.

I like reading and writing about the problems that fly under the radar. I like brining them to peoples attention because they will not see it on t.v. or in the newspaper.
Most people just write off the tropics as something not to worry about because scientist point out that they are highly adapted to heat. But it has come to my attention that it is completely the opposite. We should be paying a lot more attention to the tropics because it requires half as much heat as the Arctic does to see equal amount of change in the ectotherms. The tropics are so vulnerable because it has such a vast biodiversity. The temperature increase is going to harm the Tropics and we are slowly destroying it by cutting down much of it for paper manufacturing and oil.

“An example of deforestations”

I don’t think that the tropics deserve more attention than other areas on earth, I think every area deserves more attention that they are getting. The world needs to get the word out to more people on how our earth is being destroyed slowly by every single one of us on the planet.

Our Disappearing Beauty

This week I found an article about biodiversity that really hit me hard. I am a person who loves to travel the wonders of our world. I especially love traveling to places with beautiful warm blue oceans, I love to scuba dive and snorkel around the great coral reefs that are usually so abundant. The places that I love seeing are disappearing with the increase of pollution in our world. Not only are we not going to be able to see beautiful waters with amazing coral and biodiversity but it will change our lives more than we think.

In the article written by Ricmak, “Not good enough: Copenhagen accord may doom coral reefs”, Ricmak talks about how our plans to reduce our emissions by 50% by 2050 which will limit increasing temperatures to 2 degrees, will not be enough. In a previous article that I published I spoke about the Copenhagen meeting with the strong world powers and this author is referring to that meeting. He argues that if we do not use a more aggressive reduction that limits our global emissions, a global temperature increase could rise 4.2 degrees by 2100 instead of a 2 degree change if nations agree to a 50% reduction. That means so much to our earth.

It means polar ice caps melting because of an increase in our hole in the stratospheric ozone, causing sea levels will rise and oceanic temperatures will rise also. Which means that there will be more coral bleaching and the acidity levels in the ocean will rise due to the Carbon dioxide in the sea water. There are so many different aspects of our world that this is going to affect, but the scariest one that I want to talk about is how it is going to affect our diversity. I agree with the author that we need to use a more aggressive approach to solve our pollution problems faster. All these horrible things are going to hurt our ocean and our planet beyond measures that a normal citizen may realize. Not only are we not going to be able to see the beautiful ocean like we do today, but it is going to affect what we can eat out of the ocean.

The reefs that we find so beautiful are home to more than 25% of the oceans species and healthy reefs provide the primary source of protein to over one billion people globally. So what do you think is going to happen to all those people that need that protein to survive? Also not only do we need the reefs for a source of food, but it also provides beneficiary chemical compounds for cancer that are isolated in the species found in healthy coral reefs. Destruction like this is happening all over the world, our ocean is just one of them. Another horrible destruction that is happening is the destruction of our forests. Forest supply just as much if not more to our world. Important chemicals are taken from the rain forest as well for beneficiary medicines for medicines.

We need to inform more people that this destruction is going to harm us ALL. I think it is a just a lack of knowledge amongst most of the people in this is world that is stopping us from making significant progress. I want to make everyone think, “what can we do about it? what will we do about it?”

I found it really interesting that when I went to hawaii this summer there was a beach that went through a special procedure to preserve their coral beach. Before you were allowed to enter the beach you had to pay a fee, the money went to preserving the nature of that specific beach. Also before you were allowed to enter the beach you had to watch a video on how to properly act around the beach and in the water because of the beautiful coral it had. The video pointed out what we can do to help preserve the life of the coral and prevent further human destruction by contact. I think that is one great way to inform people that is going on.
