Methods of Conserving Marine Life

More than 70 percent of Earth's surface is covered by ocean. Ocean ecosystems offer diverse life forms, ranging from mammals to plankton. Ocean life supports our food supply, jobs, economy, environment and health. However, marine habitats have become threatened and been destroyed by pollution, overfishing and global warming. Many species have already been lost or are currently endangered. In order to help save ocean life and preserve this valuable resource, we must reduce our negative impact and put simple actions and solutions into effect.

Reduce Your Plastic

• Plastic debris is very dangerous to sea life because animals can mistake it for food or become entangled in it. As plastic pollution breaks down, it dispenses toxic chemicals into water, contaminating marine life and the seafood we eat, therefore negatively affecting human health. To keep plastic out of our oceans, reuse and recycle. Cut down on plastic waste by eliminating disposable plastic products and using reusable shopping bags, lunch bags, water bottles, mugs and sandwich containers. Always cut up plastic cans and bottle six-pack rings that can be harmful to ocean animals. 

Choose Sustainably Caught Seafood

• Overfishing is depleting our fish populations and disrupting ocean ecosystems. This threatens our food supply and can cause devastating job losses. Studies have shown that 90 percent of large predatory fish species, including shark, tuna and swordfish, have already diminished. In order to save marine life and keep enjoying fish as a healthy food, always ask where your seafood comes from and how it has been caught. Buy fish that are certified sustainable and whose capture has the lowest impact.

Reduce Carbon Emissions

• Oceans are absorbing an excessive amount of carbon emissions, disrupting the pH balance and causing oceans to become more acidic. This increased acidification jeopardizes the biodiversity of the oceans by weakening shellfish and coral and changing microscopic organisms. The effects could negatively impact food chains within the ocean ecosystems, human food supply and the economy. It could also reduce the ocean's ability to absorb more carbon dioxide, leading to extreme climate change. Contact government officials and the EPA to promote stricter carbon emission laws and to advocate for alternative energy. Reduce your own carbon emission footprint by driving less, carpooling and seeking out fuel-efficient vehicles. Buy local products to cut down on the energy used for transportation. Shut off lights, install water-conserving shower heads, use energy-saving light bulbs, buy products made with recycled materials and always reuse and recycle.

Participate in a Beach Cleanup

• A large amount of trash reaches our oceans through sewer systems and drains and is carried by ocean waves from shorelines. Some ships, although it is illegal, still dump waste into the sea. Trash endangers the health of marine animals, humans and the environment. Organize or volunteer a beach cleanup in which you can pick up trash along ocean shorelines or clean the ocean's surface by boat. Also, if you enjoy scuba diving, join a scuba organization that participates in trash removal from under the ocean's surface.

Watch Your Chemical Use

• Oceans are becoming polluted with chemical waste from households and industry, including sewage, pharmaceuticals, motor oil, pesticides, herbicides, and household cleaners. These toxins get into our oceans through drains and sewer systems. They can also be carried by wind, rain and currents. These toxins not only threaten the health of sea life but also the health of humans. Some of these pollutants are even believed to cause immune problems and disease, including cancer. To keep the oceans clean, always dispose of any chemicals properly. Bring used motor oil to a local gas station or auto shop that is certified to remove auto waste. Never dump household chemicals, medications or expired pharmaceuticals down toilets or drains. Never flush kitty litter. Use eco-friendly, natural cleaners and household products. Boycott pesticides by growing and eating organic produce. Fertilize lawns with organic, fertilizer and clean up pet waste from lawns and trails.
