In recent years, people throughout the country have witnessed a continuous socio-economic development, the living standards of people in many places are markedly improved. The urban areas, factory factories are built more and more to meet the needs of people and create jobs for workers. However, in parallel with the socio-economic development, the problem of environmental pollution in our country has been becoming a hot issue causing a lot of pressing for public opinion and cause Harms to humans, organisms and nature. So what is the cause of environmental pollution in our country today?

It is due to the following reasons:
Because of emissions from industrial and biological activities.
Because of the radioactive agents.
Due to the solid waste.
Due to noise, dust, smoke ...
Due to pathogenic organisms ...
And many other reasons.

So we can do some of the following to protect the environment:
plant many green trees
do not throw waste indiscriminately
Propagate the people to protect the environment...

Environmental pollution harms the lives of humans and other organisms, allowing pathogenic microbes to grow ... For example, transportation dust and industrial production cause lung disease. Improper use of pesticides adversely affects the whole ecosystem, affecting human health. Atomic energy and radioactive waste are likely to change in humans and organisms, causing some genetic diseases and cancer.
Environmental pollution also contributes to the degrading ecosystems and habitats of humans and organisms.

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.

Environment is an essential part of our life. A clean environment is necessary for a peaceful and healthy life. An environment is the natural surroundings which helps human beings, animals and other living things to grow and develop naturally. But nowadays, our environment is disturbing in many different ways. Any type of disturbance in the nature’s balance affects the environment totally. It does not only ruin human lives but also affects on all living beings. We can save our environment with the little step taken by everyone on the earth. We should reduce the amount of waste, throwing wastes properly to its place only…and many other simple ways. It is very important to save environment for human existence. When we protect the environment, we are protecting ourselves and our future as well.

Spring vacation is just around the corner, and the dreaded state tests are inching ever closer. It is a time of year when you may be running out of ideas, patience and energy, and so is everyone around you (or so it seems). You have gone through three different behavior plans, but Madison is still acting out, and Sam continues to come late despite an untold number of phone calls home, detentions, planning sessions and positive reinforcement programs. The faculty room is rife with a combination of boring tasteless food, stale conversation and annoying complaints about you-name-it. You try to remind yourself that "no news is good news" because, although you are working your butt off, rarely if ever does anyone seem to notice.

It's easy to feel unimportant, ineffective and taken for granted. While that may appear obvious, it seems almost human nature to notice when things go either exceptionally well or horribly wrong, and to pay little attention when things simply go right. Virtually nobody pays attention when they flip a switch and the light goes on, but everybody notices when the lights go out. In a crowded supermarket, parents respond rapidly to a child's tantrum, but are far less likely to recognize compliance to a spoken request in a normal tone. At a sporting event, we might remember the great catch or the boneheaded error, but rarely do we recall the many routine plays that happened so effortlessly. How often do customer service centers hear from satisfied customers? Most people don’t write thank-you letters when the car, refrigerator or stove works. Rarely do we think about acknowledging or thanking a doctor when he gives us the right medication. Almost never do we read news stories about positive race relations or how well people are getting along.

Is it possible that you are focusing primarily on the negatives and missing the more mundane, smooth-sailing events? Might that be affecting your view of your school’s "climate?"

It Begins with You

School climate is hard to quantify but very palpable when you are in the same place every day. It is such an integral part of the daily experience and is largely determined by the leadership, your colleagues and a host of other influences, but it is primarily about feeling appreciated for what you do -- and it begins with you. Too often we fail to see how crucial each of us can be to improving our own well being and the school's climate simultaneously. Begin by seeking positive feedback for yourself and noticing the positive contributions made by others. You’ll feel better, and so will they. Here are some strategies:

  1. Give your students a class assignment to write at least two specific things about you that they like the most and that help them be successful. You can also have your students do this with each other to help improve the classroom climate.
  2. Ask parents to write down at least one positive thing they have heard or seen from their child about your class. You can make this into an extra credit assignment that requires students to return a written answer from their parents. This will give kids an incentive to interact with their parents.
  3. Ask a colleague or two to visit your classroom and observe your teaching, and then ask them to share specific things they saw you do really well, along with any suggestions they think might help you get even better.
  4. Keep a daily record or log of your and your students' accomplishments for one or two weeks. This will force you to notice when things are going well.
  5. If you are getting little notice and appreciation but deep down you know that you're a good teacher, there's a strong possibility that nobody around you is getting much, either. Be generous in your recognition of others. Notice when things are smooth sailing, no matter how rare. How often have you shared positive feedback with a colleague about how well his class passed by your room? When was the last time you thanked an administrator for her organizational effort on a day when things went smoothly, or a parent who signed the permission slip on time? Dale Carnegie once said that you could make more friends in two months by showing an interest in them than you could in two years by trying to get them to be interested in you.
  6. Create a "troubles-free" zone at your school where only good, upbeat news about faculty, students and issues can be shared. A table or two set aside in the faculty lounge can be a good place, since too often the lounge becomes an unpleasant chamber for griping and complaining.

Getting and giving positive feedback is the most direct way each of us can create a school climate conducive to high achievement and happiness. You won't be able to influence everyone or affect everything, but you may have more power than you think to make your school more of what you want it to be for yourself and others.
