Description
Although there was a time when we treated the oceans as if they were too vast to feel our impact, we now know the truth: we have contributed to global climate change, ocean acidification, and overfishing. The results are potentially catastrophic - both to marine life and to our own health. But there is a bit of light at the end of this tunnel, and it depends in part on our own daily actions.

Description
How and where did life begin on Earth? The existence of both photosynthetic and chemosynthetic food chains points to the possibility that life could have originated through two different paths. While many questions remain unanswered, two things seem certain: Life began in the oceans, and bacteria are the most successful organisms on the planet.

Over and over, humans have behaved as if a given resource were inexhaustible. That was certainly the case with worldwide industrial whaling of the early 20th century, when six species of whales were hunted to dangerously low numbers. In the near future, as their populations continue to recover, some countries are expected to promote a resumption of the commercial whale hunt.

Description
While humans have been fishing for hundreds of centuries, we have only recently had a significant impact on marine food webs. Industrialization has led to problems with by-catch and overexploitation of resources. Today, we are creating trophic cascades with long-term impacts we do not yet understand.

Description
The vast majority of animals on our planet are the gloriously diverse invertebrates. From microscopic organisms to the crab with a three-meter leg span, marine invertebrates exhibit enormous variety in form and function. They include sessile and mobile organisms, free-living and parasitic. They live at the surface and within the ocean floor sediments.

Description
Two things are clear: Almost all marine food webs are based on microscopic photosynthesizers, and only a small fraction of the energy available at any trophic level becomes available to the next level. Adaptations such as baleen, ventral pleats, and unique tooth morphology allows these large animals to meet their energy needs.
