Marine and Conservation Careers

Although they cover over 70% of our planet’s total surface, our seas and oceans remain largely unknown. Humans have explored less than 5% of our global oceans, and to this day new species are discovered daily. It is estimated that we are still yet to discover around 75% of species.

Even though our oceans are largely undiscovered, they are vital to life on earth in a variety of different ways; they control global temperatures based on oceanic currents, drive weather systems, provide transport, whilst also providing food and habitats for its extremely diverse inhabitants.
