Excerpt from a story I'll never write

Ten years ago the ocean started to dry up. It happened slowly at first, global warming being the main cause. Within a year the ocean had dropped 300 feet.
The government kept telling us it was under control, each nations leader fighting to keep their citizens calm. All the weather channels promised rain, stories of hurricanes were being told, everyone hoping they would fill the ocean back up. People began to pray for them to occur.
By the second year, entire species of fish were beginning to go extinct. Dead sea creatures were being found washed up on the shores all over the world. Once this started, every country started to rally together to figure out how to contain the fish that were still living in order to preserve the species. After 300 billion dollars and 3 more years they finally figured out a way to do that.
In that time we had lost 250 more species of sea animals, and what was left was the types of fish we were unfamiliar with. The kind that hung out in the very depths of the ocean, hiding from the light. Scientists began to experiment with the fish trying to figure out which ones were safe to eat and which ones weren't. People became upset. They began boycotting the companies and holding marches to stop them.
Conspiracies were forming saying scientists caused the ocean's water to reside just so they can get a better understanding of the fish that lived down below. Countless murders and bomb threats were happening all over the world at every laboratory and science clinic there was. The world was thrown into a chaos that distracted them from the still diminishing ocean.
By year 6 the tops of trees started to appear from under the water. The brush was thick and as you got deeper into what was once the ocean the trees started to get more tight. There were millions of them, hundreds of feet tall. Everyone was overjoyed at this sudden forest that appeared. More and more volunteers were venturing into the forests to see what there was to find. Maybe there was secret treasures to be found.
Ideas began to form of building a train to connect all the countries together to make it easier and safer for travel. The fighting shrank as the excitement grew. For the first time in a long time everyone felt hope. They stopped worrying.
Blueprints were being drawn up on how the trains would connect and how many tracks there would need to be. Engineers came up with ideas of leisure cabs for vacations and travel cabs for the commuters. People worked on how much it would cost to start chopping down the trees to make way for the tracks, but oh, how they would be set on wood for life. There were enough trees to fuel their train for centuries. Everything was finally starting to work out for the best.
That is, until people began to go missing in the forests. Everyday more and more cases of missing persons were reported. Search teams were sent out to retrieve them only to get lost as well. Theories were formed that there were creatures in the forests. With the deep ocean there to hide them before, they were now well exposed to the light and the world above them. How much longer would it be before they began to move closer inland instead of hide away like they were so accustomed to before?
In a panic, new plans were drawn up in place of the train plans. With this new threat to the world everyone began to build a wall that would be so huge that nothing could get in, and no one could get out.
