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:

  • Pollution is one of the biggest global killers, affecting over 100 million people.
  • Over 1 million seabirds and 100,000 sea mammals are killed by pollution every year.
  • The Mississippi River carries an estimated 1.5 million metric tons of nitrogen pollution into the Gulf of Mexico each year, creating a “dead zone” in the Gulf each summer.
  • 40% of the freshwater lakes in the US are too polluted for fishing, aquatic life, or swimming.
  • 1.2 trillion gallons of untreated sewage, storm water, and industrial waste are dumped into US water every year.
  • In 2010, recycling and composting prevented 85 million tons of pollution.
  • Cleanups can save animals lives and discourage people from littering in the future.
Cleaning up Ocean Pollution

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. Read about conservancy and restoration – and then share what you have learned.Reduce your family’s use of chemicals. Use fertilizer minimally, buy organic fruits and veggies, and choose non-toxic cleaning products.Trash doesn’t disappear. Moving water can carry loose trash to the ocean.Invest in reusable bags, beverage cups, and non-plastic containers. Always recycle.Never litter and be a part of the solution by participating in beach cleanups.Only buy products that you can guarantee were sustainably harvested. Demand sustainable seafood at the grocery store and in at favorite dining spots.On this little blue planet, we are but one species and we are the most dangerous to all the others. Our oceans and sea life are not replaceable. We can and must do our part to clean, conserve, and improve the conditions in our planet’s oceans.Without the oceans, we put our lives in jeopardy. Let’s do the smart thing and take care of our oceans.

        If I were the principal, I would change a lot of things about my school. As a student, I understand well the feeling of being criticized and scolded by the teacher before the flag salute, feeling very uncomfortable, so if I were the principal, I would change my attitude towards the students. born to make them as comfortable as possible. In addition, I will improve your skills, including school rules, which are very important for learning and also for the daily life of both students and teachers. In addition, I will not force students to adhere to the uniform excessively, there will be days when I can wear clothes that are free but also suitable for studying. All of the above is just my opinion, of course it contains many shortcomings, hope everyone, especially teachers, will correct them.

If I could I would make one day per week a non-student day devoted to teacher growth and learning. This would provide generous time to think, plan, assess, reflect, work with colleagues, examine student work repeatedly, learn more about learning, learn about student trauma, learn more about teaching, learn more about content. Right now because teachers supervise the students, time for teacher growth is limited and often placed at the end of a long, tiring day; or teacher-time is created by using guest teachers (who are not always predictable in capacity or attendance); or teacher learning happens in the summer which is like getting a blast of thinking and learning without any opportunity to try it out and make it stick  . I would hire a team of camp counselors to be available for all student free time on campus to lead games, activities, and supervise student fun. Right now we hire campus supervisors who mostly act as clean-up people and overseers and so interaction with students is very authoritarian. A more camp like environment would help students to interact in a positive manner and enjoy their time in school to a greater extent. Having folks on campus trained as camp counselors could provide flexibility in the school day where teachers could excuse part of their students to have fun with counselors while others work on something specific with the teacher .Classrooms (and class numbers) would be flexible in space, seating, and furnishings. So we would have larger theater like lecture halls as well as small books and crannies for small group tutoring. Classes in most schools that I have been part of have been very inflexible. Each class is assigned between 25–35 students in room of about 2–300 square feet. Once desks and students are in the room, there is little space for any movement, small group areas, quiet spaces, etc.

The classroom is a place where we play and learn so protecting it is something every student must know. So what do we need to do to keep it clean. First we need to clean, sweep the house, wipe the table cleaning table ..., next we should not throw garbage indiscriminately, but throw it in the trash. Put more trees in the classroom to keep it cool and educate your friends about how to stay clean in class. I criticize some of you for not knowing how to keep your classroom clean. The above actions can help us to protect the environment in which we study in a cool, hygienic way so that we always learn to keep a happy spirit in every class.

If I were the principal, I would sit up straight like a student guided by a teacher. I will always smile at everyone and not talk when I'm angry. The principal doesn't let students play soccer at the school gate, she has to build a place for students to play soccer… and I will build a classroom for music, because there are students who love to study music but do not have their own classroom.

We all know that climate change is getting more complicated. Scientists say that humans are one of the major contributors to environmental pollution.

It can be seen that environmental pollution has caused global warming, sea level rise, bipolar, ice storms, storms and floods, droughts, accidents, Conflict and war, causing the Earth to lose biodiversity and destroy the ecosystem.

Evidence for these issues has been reflected in a number of recent extreme climate impacts, such as the 250 million people affected by floods in South Asia, Africa, and Mexico.

Southern European countries face the risk of serious drought that can lead to bushfire and desertification. Western European countries are threatened by major floods, rising sea levels as well as severe freezes.

Major storms that have occurred in the United States, China, Japan and India ... have been the cause of global warming for decades. The data obtained by satellite each year shows that the number of storms has not changed, but the number of hurricanes, hurricanes, intense intensity and destructive power has increased, especially in North America, South-West Pacific Ocean, Indian Ocean, North Atlantic Ocean.

A 90% probability study shows that at least 3 billion people will suffer from food shortages by 2100, due to warming of the Earth.

In our country of Vietnam, the environmental pollution is also worse than ever: consecutive days in May 2016, Buoi River (in the area of ​​Thanh Hoa and Hoa Binh provinces There is a phenomenon of dead fish emerging on the water, drifted to the shore as a source of polluted river water, causing concern for many households living on both sides of the river.

That is not to say, serious marine environmental problems causing seafood died in the four coastal provinces of Central Vietnam (Ha Tinh, Quang Binh, Quang Tri, Thua Thien-Hue) occurred in early April 2016.

Then in the morning of October 2, in the West Lake area, Thanh Nien road, people discovered large amounts of dead fish, white floats on the lake. The bodies of thousands of fish, aquatic animals floating on the water, carrying a foul smell very unpleasant.

In addition, environmental pollution has also led to a series of people with cancer, the appearance of cancer villages more and more. That is the big impact from environmental pollution and climate change.

Dear Mr. Antonio Guterres,

Protecting the environment and combating climate change is an urgent task for all nations of the world to protect our own lives. I am very hopeful, in a new position, that he will take decisive action to prevent environmental pollution and climate change not only in my country but in all countries of the world. The world is full of green.

I don't agree that opinion. If you just learn Math ,Literature and English ,you just good at 3 of these. You have to learn another subject to know about  what happen to the world. You learn Geography to know geographical location , this  subject can help you capture the place easily . You learn technology to know how to fix electricity. So you have to learn all subjects because it can help you in your life and your job in the future

The most important subject is writing. Not literature, but writing. This will be critical no matter what you do, whether you’re a nurse, an administrative assistant, or the president of the free world. And the understanding of maths must be considered the criterion for intelligence as well. Maths is life and no subject can run without maths. All the problems in the world required maths to solve it. Same way, anything requiring calculations is dependent on maths like every step even you make. Without proper calculations one may succeed accidentally in getting something but to continue getting the same results one surely has find what calculations made the success possible. Futhermore, English is an universal language, once you know how to speak, write and read English, you can talk to whoever and whenever, it especially good for your higher education like when you go to the college or university because some books are written in English. In conclusion, I think that students must study many things including Maths and Literature and English in order to succeed in the modern world.
