Oceans and the life they sustain are vital to humankind. Unfortunately, overfishing, climate change, and pollution threaten these habitats.
The oceans are one connected body of salt water that covers more than 70 percent of the Earth, and we depend on these waters for human survival. They influence everything from the weather to the food supply to the health of seaside communities. Yet, we are the greatest offenders when it comes to pollution.
The oceans are also teeming with creatures that are critical to our ecosystems. Fish, dolphins, squid, octopuses, eels, and whales populate the open ocean, while lobsters, starfish, oysters, crabs, and snails scurry about the ocean bottom. Mammals like walruses, otters, and polar bears depend on the ocean for their survival as well. Coral reefs are a biome of colorful activity found in shallow, tropical waters.
All areas of the ocean are impacted by human activities. Lost or discarded nets, spilled oil and garbage, runoff, and sewage are all creating dead zones in the oceans. Excess carbon dioxide turns ocean waters acidic, and freshwater from melted glaciers will alter the weather-driving currents.
Heartbreaking Ocean Pollution Facts
Scientists estimate how much floating garbage is out there, but not even oceanographers can tell us exactly how much – the oceans are just too big. In 2002, Nature magazine reported that, “…during the 1990s, debris in the waters near Britain doubled; in the Southern Ocean encircling Antarctica the increase was a hundredfold. And depending on where they sample, oceanographers have found that between 60 and 95 percent of today’s marine debris is made of plastic.”
Where does all this garbage come from?
Plastic and other garbage enters the ocean when people throw it from ships, leave it in the path of the tide, when rivers carry it there, or when sewage systems and storm drains overflow. In spite of the Ocean Dumping Reform Act, “…the US still releases more than 850 billion gallons of untreated sewage and storm runoff every year,” according to a 2004 EPA report.
This problem is significant because plastics do not degrade in seawater. Rather, they accumulate daily, and, thanks to ocean currents, the plastics travel thousands of miles.
As of April of 2017, scientists estimated that about 19 billion pounds of garbage are currently present in the world’s oceans.
“We’re being overwhelmed by our waste,” said Jenna Jambeck, an environmental engineer who led the 2015 study that determined this staggering number. According to Jambeck, ocean waste amounts will double by 2025 unless we do something on a global scale to reduce ocean waste.
Plastics are the top type of garbage found in the ocean. Ocean Conservancy, a nonprofit that organizes an annual coastal cleanup event in more than 150 countries worldwide, estimate that plastic debris makes up around 85 percent of all the trash collected from beaches, waterways and oceans.
Because plastics don’t biodegrade, they simply break down into smaller and smaller pieces as they are exposed to sunlight. These microplastics are shorter than 5 millimeters long, and some are microbeads.
The United Nations Environment Program note that, “…there could be as many as 51 trillion microplastic particles in our seas.” What is particularly alarming is the five, enormous swirling garbage convergences called “gyres”. These large garbage islands are the subject of new and innovative ocean cleaning efforts and technology.
One of the most troublesome sources of ocean garbage is litter from single-use plastic products ― plastic bags in particular. These plastics are threatening at least 600 marine life species, including leatherback turtles, whales, and seabirds. These animals mistake the plastics for food and cannot digest them, and the plastics eventually kill the animals.
People need to be educated about how widespread ocean pollution is and how it not only affects marine life, but people and the environment as well.
For example:
It is critical that we, as residents on this planet, join together to fight ocean trash. There are multiple agencies, nonprofits, and corporations who are joining the fight, and we can support them.
The International Coastal Cleanup organization started more than 30 years ago, when communities came together to collect and document the trash along their Texas coastlines.
The organization connected with the Texas General Land Office, local businessmen and women, and other ocean-lovers, and planned what would be Ocean Conservancy’s first Cleanup. Volunteers didn’t just pick up trash; they recorded each item collected on a data card in order to help find ways to eradicate ocean trash moving forward.
The Cleanup has grown vastly in 30 years. Volunteers from states and territories across the US and more than 100 countries participate in a Cleanup event every year.
Renee Tuggle, the Texas State Coordinator for the International Coastal Cleanup, said, “What I have learned from the Cleanup experience, is that even though the Cleanup started in Texas with a small number of 2,800 volunteers… it has grown into a massive cleanup that involves both national and international volunteers all pitching in for the same common goal of cleaning up our coastal waters and taking care of our beaches. I am proud to be a part of this global movement and I appreciate all of the help and support I get from the Ocean Conservancy staff.”
At a former naval air station in Alameda, California, across the bay from San Francisco, workers are welding a football field length black tube together. It is a single piece of a larger system designated to attack the Great Pacific Garbage Patch.
Boyan Slat, the innovator behind the idea, presented his science at a TEDx talk and The Ocean Cleanup idea began. At just 18-years-old, Slat had discovered that cleaning up microplastics and microbeads currently in the ocean could take almost 80,000 years. Now, his organization is poised to clean up a huge majority of the Great Pacific Garbage Patch in just five years.
There are also things individuals or small groups can do to help:Be conscious of your energy use at home and work. Switch to compact fluorescent light bulbs, take the stairs, and avoid oversetting your thermostat.When you are grocery shopping or dining out, reduce the demand for overexploited species by choosing sustainably sourced seafood.Plastics kill tens of thousands of marine animals every year. Carry a reusable water bottle, use cloth totes for shopping, and always recycle whenever possible.Always clean up after yourself and participate in a beach cleanup. Explore the ocean but don’t interfere with wildlife or remove rocks and coral.Avoid buying items like coral jewelry, tortoiseshell hair accessories, and shark products.Read pet food labels and consider seafood sustainability when choosing food for your pet. Don’t stock your aquarium with wild-caught saltwater fish, and never release aquarium fish into natural bodies of water.Consider giving financial support or offering your time at volunteering.Research the ocean conservation positions of public officials before voting. Patronize restaurants and markets that offer only sustainable seafood.Practice responsible kayaking, boating, kayaking, and other activities on the water. Don’t ever litter and be aware of marine life in the water.The more you learn about this critical system, the more you can share that knowledge to educate others.The threats to our ocean ecosystems seem overwhelming. The oceans experience pollution, overfishing, climate change, and other issues. How can we make a difference as individuals? We can make a big difference starting here:Learn about the ocean and how you impact the ecosystem.

Let’s do the smart thing and take care of our oceans.
Environment is a set of natural factors that serve human life. These factors interact together to form an association that has a positive or negative impact on people's life.
People are facing many risks because of the imbalance of the environment. It causes serious harm to human health: It causes terrible diseases such as cancer, dermatitis, eye inflammation, diarrhea, epidemics that are difficult to control, ... Not only that, air pollution also indirectly causes water pollution, emissions such as carbon dioxide, sulfur dioxide will combine with water vapor to form dangerous acid rain, both polluting water sources, harming human health, and destroying construction works. Causing consequences such as forest fires, causing ecological imbalances, destroying the habitats of many wildlife species, making them close to the brink of extinction. The amount of smoke emitted from factories and factories is also one of the main reasons for destroying the ozone layer, causing ultraviolet rays to shine on the earth, seriously affecting human life.
Therefore, we have to actively plant trees to cause forests, consciously dispose of garbage at the right place. In industrialization activities, it is necessary to involve the state in strictly managing the standard waste treatment process, before discharging it into lakes, rivers and streams. Actively clean and clean the residence, keep the living environment fresh, clean and beautiful, actively propagate with everyone and every house about the harmful effects of environmental pollution, mobilize people to actively participate and have awareness of environmental protection. Please use energy saving, turn off lights when not needed.
Let's join hands to save energy, protect the environment - our invaluable resource.
Energy is very important to our life.Today I want to talk you about some easy ways to save energy.Firstly,we should save energy by turning off all the appliences such as: lights bulb,fans,.......Secondly,we should take shower instead of bath,use as enough water as need,.....Finally we should go to school by bike or on foot if the distance between our house is short,....We should save our energy to protect the natural resources of the earth

We are trying to find solutions to environmental pollution problem. People should stop cutting trees for timber, Instead, they should plant more trees and forests. They should reduce using cars and motorbikes that cause noise and air pollution. We should prevent farmers from using fertilizers and pesticides that damage the soil. People should not litter on the land and in the water. We should prohibit factories from dumping industrial wastes into rivers and lakes. It is high time governments over the world had measures that require companies and individuals to stop or cut down on polluting activities.

My house primarily relies on electricity and gas for energy. Electricity powers most appliances and lighting, offering convenience but contributing to high consumption. Gas fuels the heating system, providing warmth efficiently but releasing emissions. To save energy, I've adopted simple habits: switching to LED bulbs, unplugging devices not in use, and using energy-efficient appliances. I've also improved insulation and sealed drafts to minimize heat loss. Moreover, I'm conscious of water usage, opting for efficient fixtures and practicing conservation. These steps not only save energy but also reduce environmental impact, aligning with my commitment to sustainability.
I think we can do many things to improve the environment around us. Firstly, we can reduce the amount of rubbish we produce for example glass, paper and plastic, etc. Secondly, we reuse as many things as we can for example shopping bags, old clothes, old books, … Finally, we can recycle used things around us such as plastic bags, water bottles, old paper, glass and so on.

Since several environmental problems have been caused by humans’ forces, we need to act responsibly to reduce the damage that we are doing to the Earth. This essay will explain environmental problems and what governments and individuals can do to address these problems.
Two of the threats to the environment are air pollution and waste. Global warming, which is well-known as a global issue because of its devastating effect on the environment, is a result of gas emissions from factories and exhaust fumes from vehicles. In addition, the increase in human population comes along with a huge quantity of waste, which contaminates the earth and pollutes rivers and oceans.
On one hand, governments could reduce air pollution in many ways. First, they could introduce laws to put a limit on factories’ gas emissions or force companies to use renewable energy in production. Second, they could also innovate the public transport system to become more convenient and greener. In this way, governments can encourage people to take public transport instead of driving, therefore reducing emissions.
On the other hand, individuals should also be responsible to lower down pollution levels in their surroundings. They can take buses and subways or other means of public transportation rather than driving, which could reduce the number of exhaust fumes from vehicles. Also, people should purchase reusable products and recycle as much as possible to avoid releasing too much waste. For example, Vietnamese people are recommended to use reusable or paper bags when going shopping instead of plastic bags to cut down on plastic bags consumption.
In conclusion, both national governments and individuals must understand the harmful impact they have on the environment and be responsible to ease the damage.
