Due to oceans taking up more than 70.8% of Earth’s surface, humans depend on oceanic resources for water, food, products, and most importantly, air (Boeuf, 2011). Without biodiversity, ecosystems cannot thrive and become unbalanced causing every species on the Earth to suffer. In the 1960s, Rachel Carson was one of the first marine biologists to inform the public about the need for marine conservation. According to Marine conservation biology: The science of maintaining the sea 's biodiversity, Carson began a movement that led to “a flood of new and strengthened environmental laws in the United States and beyond” (Norse and Crowde, 2013, p.1). By creating the start of marine conservation funding and support, it changed the public 's point of view and help them understand that the ocean is not as vast and resilient as we once …show more content…
The increase of water traffic for trade creates a way for invasive species to stow away on ship ballasts when traveling to different ports. This hitchhiking can easily be done when the ships take in the water to counterbalance cargo weight and release the water when they reach their destination. (Sala, 2008) Nonnative species can either die from being introduced into the new environment, or they take over the native species and ruin the ecosystem. A local example of how marine invasive species affects an ecosystem is the zebra mussel, originally from the Black Sea, that found their way into the Great Lakes from European ship ballasts. The Minnesota Department of Natural Resources (2016) reports that the zebra mussel ‘attaches and smothers’ native mussels. In order to thrive, this invasive species eats tiny food particles that were originally eaten by other species. Invasive species can change the food web, decrease biodiversity, and alter living conditions, but nonnative species can be stopped if countries can work together to monitor ports and ship
