Monterey Bay on California's coast is one of the most diverse marine ecosystems in the world, its giant kelp forest bursting with life, from microscopic plankton to visiting ocean giants. The secret key to success in such a busy microworld is balance. Steve Backshall guides us through the unique geography of the bay and introduces some of its key characters in a quest to find the one species that keeps life in the kelp forest in check.

The aquatic biome is divided into freshwater and marine regions. Freshwater regions, such as lakes and rivers, have a low salt concentration. Marine regions, such as estuaries and the ocean, have higher salt concentrations.

Marine is the largest biome in the world. It takes up a whopping 70% of the Earth and accounts for 90% of the world’s water supply. This biome boasts more than 230 distinct species.

Ocean Conservation

Oceans cover over 70% of the Earth’s surface and contain a diverse array of species, habitats and ecosystems. As many as 100 million species live in our oceans, contributing to a rich biodiversity far exceeding that found on land. Marine extinction risk has ramped up rapidly in the past 50 years, to converge upon the level of risk seen on land.

Biomes exist on land and in oceans and differ according to their location and geographic characteristics.

Topography (the shape of the land), climate and soils mean similar land biomes can have different species of plants and animals.

Food can be produced from different biomes when people change the environment for example by ploughing the land, building greenhouses to grow plants, draining swamps and wetlands, building terraces on slopes etc.
