BigAnimals expeditions travels the world to find the most memorable underwater adventures, and we find so much passion about the value of the nature and the importance of ocean conservation among our guests. Of course, we aren’t the only ones thinking about the human connection to nature, both with what we do to help nature and, unfortunately, what we might do to hurt it. Filmmakers have looked at this also.

Here is some of their work about the human connection with oceans that are worth catching on DVD.

Bag It traces the journey of a plastic bag. It may seem like a small thing, but when you consider how many plastic bags we use and throw away, it becomes a huge factor in the health of the earth and its oceans. Bag It shows how these bags eventually end up in landfills, get stuck in trees, and pollute the ocean. An area of the Pacific Ocean has been nicknamed the Great Pacific Garbage Patch; parts of this “garbage patch” contain concentrations of plastic that are 40 times greater than that of plankton. Plastic is not biodegradable in water. It gets broken down into smaller and smaller pieces causing fish to confuse this plastic with food. The result – many species of fish have been found with large amounts of plastic in their stomachs.

Tapped follows a similar storyline, but instead focuses on plastic water bottles. Many people rarely think about the environmental impact of grabbing a fresh bottle of water. But that impact is huge – there is an equivalent to 9 million football fields of plastic in the ocean – and chemicals in plastic, like BPA, have adverse effects on humans.

While Tapped and Bag It relate indirectly to the ocean, two films, The End of the Line and A Sea Change, are more directly significant. They explore the devastating consequences to marine life of overfishing and ocean acidification.

The End of the Line investigates current fishing methods and dramatically shows how, if we continue fishing as we do and eating unsustainable fish, scientists estimate that we will run out of fish by 2048. However, there is a silver lining in this film, and that is – the solutions to overfishing are simple and doable. They include:

• reducing the number of fishing boats across the world
• protecting large areas of the ocean through a network of marine reserves off limits to fishing
• educating consumers that they have a choice by purchasing fish from independently certified sustainable fisheries

A Sea Change hones in on ocean acidification and the effects of excess carbon dioxide and global warming on our oceans, fish, and marine life.

Each of these films are eye-opening portraits of human activities leading to the demise of our oceans, the animals and fish that live in them, and eventually the circular effect these practices will have on humans in the future. Have a look at them and see why people have learned to love the world’s oceans and all the animals that inhabit them.
