I have been pondering the trumpet judgments as I proceed through my outline of Revelation.
I spent some time a few months ago researching the 1st trumpet – what is the impact on the world with losing 1/3rd of the trees? My first thought is that there will be a dramatic increase in CO2 – carbon dioxide. Depending on where the trees are wiped out, I think it is safe to say that many people will die from lack of oxygen. In addition all the green grass is burnt up. I also theorize that it may cause a lot of erosion – similar to what happened in the Dust Bowl of the 1930’s in the Midwest. Farmers plowed up so many fields for grain and cut down so many trees, in addition to several years of drought, that almost the whole midwest became a desert.
So, that moves me on to the second trumpet. What could be the ecological impact of 1/3 of the ocean becoming blood? The scripture tells us that 1/3rd of sea creatures die and 1/3 of ships are destroyed. I assume in some sort of Tsumani effect from the mountain that falls into the ocean that causes it to become blood. The ocean has around 1300 million cubic kilometers of water – so imagine around 400 million cubic kilometers of blood! Ick! And since the oceans cover around 64% of the earth’s surface – 20% of the earth’s surface will be blood!
Here is a map of the oceans of the world. Can you imagine 1/3rd of them blood?!
Here is another picture – detailing the water cycle.

I am not sure how the judgment will impact the water cycle and therefore rain, snow, ice, irrigation of land and springs and so on. I imagine the change will be drastic and not good. Probably resulting immediately in drought, but who knows for sure.
So, just a few thoughts about the second trumpet judgment. I don’t have any conclusions, but I find it fascinating to think about what it will be like and what may happen.
