    Experts continue the search for safer and cleaner sources of energy to transition from the use of fossil fuel. Farmlands are also increasingly being devoted to the production of bioethanol. There is an issue though when it comes to using land crops for fuel as this might affect the supply of food in the long run and might increase costs.

    A team of experts at the Zoology Department of the Tel Aviv University and scientists from the Israel Oceanography Institute, and Ben Gurion University have explored the seas to find a renewable source of energy which will not endanger biodiversity, natural habitats, and food sources of human. According to them, marine macroalgae can easily be grown faster than land crops and be harvested for fuel without compromising the usage of land. Seaweeds is a great source of bioethanol which has not been explored much yet.

    The team of researchers is trying to develop methods to cultivate seaweeds and harvest them as a source of our renewable energy. The seaweeds can grow without any problems along coastlines and they can also help clean the waters of excess nutrients brought about by aquaculture or human wastes.

    Biomasses produced on land imposes problems like damage to our environment while experts sees the use of seaweeds for biofuel as a good solution to some marine problems. A lot of coastal regions like the Red Sea near Israel is suffering from pollution caused by humans.

    The scientists developed CAMUS or Combined Aquaculture Multi-Use Systems, a way to grow seaweeds and convert it to biofuel. This system takes into consideration the realities of the water environment and the activities of human in it.

    CAMUS will be tapping multiple species to make sure wastes in the marine environment can be converted to resources which will be productive like biofuel and at the same time help decrease the effects of pollution.
