We should not stand-out emissions and fuel economy

We should avoid dirty water filter and water

Do not pour too much garbage, dirt and micro-ground insect, Limit pesticide spray or pour directly into the soil chemicals

Planting more trees, go lightly, whispered. Small cell out- turn go- neighbors do not mind. Avoid causing noise to disturb others and hurt the ears.

No burning of forests and cut trees

Marine pollution is a growing problem in today’s world. Our ocean is being flooded with two main types of pollution: chemicals and trash.

Chemical contamination, or nutrient pollution, is concerning for health, environmental, and economic reasons. This type of pollution occurs when human activities, notably the use of fertilizer on farms, lead to the runoff of chemicals into waterways that ultimately flow into the ocean. The increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms, which can be toxic to wildlife and harmful to humans. The negative effects on health and the environment caused by algal blooms  hurt local fishing and tourism industries.

Marine trash encompasses all manufactured products—most of the plastic—that end up in the ocean.  Littering, storm winds, and poor waste management all contribute to the accumulation of this debris, 80 percent of which comes from sources on land. Common types of marine debris include various plastic items like shopping bags and beverage bottles, along with cigarette butts, bottle caps, food wrappers, and fishing gear. Plastic waste is particularly problematic as a pollutant because it is so long-lasting. Plastic items can take hundreds of years to decompose.

This trash poses dangers to both humans and animals. Fish become tangled and injured in the debris, and some animals mistake items like plastic bags for food and eat them. Small organisms feed on tiny bits of broken-down plastic, called microplastic, and absorb the chemicals from the plastic into their tissues. Microplastics are less than five millimeters (0.2 inches) in diameter and have been detected in a range of marine species, including plankton and whales. When small organisms that consume microplastics are eaten by larger animals, the toxic chemicals then become part of their tissues. In this way, the microplastic pollution migrates up the food chain, eventually becoming part of the food that humans eat.

Solutions for marine pollution include prevention and cleanup. Disposable and single-use plastic is abundantly used in today’s society, from shopping bags to shipping packaging to plastic bottles. Changing society’s approach to plastic use will be a long and economically challenging process. Cleanup, in contrast, may be impossible for some items. 

Nonetheless, many countries are taking action. According to a 2018 report from the United Nations, more than sixty countries have enacted regulations to limit or ban the use of disposable plastic items.

Topic 2:Saving energy

Most of the air pollution results from the burning of fossil fuels, motor vehicles, factories, aircraft and rockets. This can cause acid rain which damages water, soil, and vegetation. Air pollution also contributes to the greenhouse effect which can lead to a series of environmental problems such as global warming, polar ice melting, rise of sea levels and loss of land.

Water pollution is a result of dumping pollutants such as detergents, pesticides, oil, and other chemicals in rivers, which makes the water unclean or contaminated. Rubbish blockages in rivers can also cause pollution.

Soil pollution is a consequence of human activities that alter ecological factors that cross the ecological boundaries of the communities living in the soil. The land environment is home to human beings and most of the shallow creatures, the foundations for civil, industrial and cultural constructions. Land is a precious resource, people use land resources for agricultural production to ensure food supply for people. But with the pace of population growth and the pace of industrial development and urbanization, the area of ​​arable land is shrinking and land quality deteriorates, the average land area head drops. Parularly in Vietnam, the actual depletion of land resources is very worrying and serious.  What do we need to do to protect the environment? That is the question that every one of us needs to answer. In my opinion, protecting the environment is the responsibility of the whole community. Everyone must have a sense of protection. The green, clean, beautiful environment will make our lives better. From the house to the alley, from the alley to the school etc. The place is also clean and airy, many trees, air will be fresh, health will be guaranteed. That everyone wants. At present, I see my class, our school where the concentration of people, not very clean, garbage also lunged, trees are still less. On the street, there are public trash but few people put garbage in the bin, you do not throw it, making the street scene is not beautiful. To protect the environment, I feel we must always have a sense of environmental protection in parular: Do not throw garbage indiscriminately, do not discharge dirty water into ponds, do house cleaning, alleys, schools, not breaking flowers ... and propaganda for people always have common sense and responsibility for environmental protection.
