Eat more fruits, vegetables, whole grains, fish or other first grade protein sources like soy and dairy products. Don’t skip breakfast as it is the most important meal of the day which gives you energy for whole of your day. Have smaller meals at regular intervals of 2-3 hours. This will keep your metabolism in control. Have enough water and fluids (not cold drinks) throughout the day. Keep the levels of salt and sugar low in your daily diet. Don’t have fried foods. It’s OK to have rich food once in a while but don’t make it a regular thing. Avoid junk food as much as possible. So, make a habit of exercising regularly, even if it is brisk walking for 30 minutes. Of course, it will be good if you can exercise a little more and that’s a must when you are overweight. Choose your exercise as per your interest to remain motivated. If you don’t like gym, don’t go there. Do aerobics or yoga. If not, go cycling, jogging, swimming or dancing. When confronted with a problem, don’t think negative. Think about the best and the worst situation that the problem can get you in. Now, first focus on the worst situation- is it so bad that you need to lose your health by succumbing to the stress? If not, half of your problem is solved. Now focus on the best situation and the ways that can be employed to reach it. Make a list of solutions- mentally or on paper. Now, keep on reviewing and omitting the items (that now don’t look so good a solution) at every repetition. Ultimately, you will be left with one or two options to try for solving your problem. This will definitely help in relieving your stress. If you are not able to relax and your mind wanders around, you might take help of relaxation techniques like meditation. Learn new skills, develop your one time favorite hobbies that you had not been able to pursue due to busy work schedules. Read, write, sing, dance, socialize, party, travel- anything that will make you happy.

Favourite film:
There are many films in Vietnam such as: Co ba Sai Gon, Co gai den tu hom qua,... but I like Chang trai nam ay best. It's a moving film. It was derected by Quang Huy. It stars Son Tung M-TP, Hariwon, Hua Vi Van, Ngo Kien Huy and Pham Quynh Anh. It was made in 2014. It's about the young singer who has a cancer. The ending is moving so that I cried. The film has special effect and very good visuals. It has sweet melody. The critics say it a must see. I agree because the story is moving and the acting is excellent. Go and see it if you can.

Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth. It’s the reason we have Kool-Aid and brilliant blue waterfalls. It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.

Categories of Water Pollution

Groundwater

When rain falls and seeps deep into the earth, filling the cracks, crevices, and porous spaces of an aquifer (basically an underground storehouse of water), it becomes groundwater—one of our least visible but most important natural resources. Nearly 40 percent of Americans rely on groundwater, pumped to the earth’s surface, for drinking water. For some folks in rural areas, it’s their only freshwater source. Groundwater gets polluted when contaminants—from pesticides and fertilizers to waste leached from landfills and septic systems—make their way into an aquifer, rendering it unsafe for human use. Ridding groundwater of contaminants can be difficult to impossible, as well as costly. Once polluted, an aquifer may be unusable for decades, or even thousands of years. Groundwater can also spread contamination far from the original polluting source as it seeps into streams, lakes, and oceans.

Surface water

Covering about 70 percent of the earth, surface water is what fills our oceans, lakes, rivers, and all those other blue bits on the world map. Surface water from freshwater sources (that is, from sources other than the ocean) accounts for more than 60 percentof the water delivered to American homes. But a significant pool of that water is in peril. According to the most recent surveys on national water quality from the U.S. Environmental Protection Agency, nearly half of our rivers and streams and more than one-third of our lakes are polluted and unfit for swimming, fishing, and drinking. Nutrient pollution, which includes nitrates and phosphates, is the leading type of contamination in these freshwater sources. While plants and animals need these nutrients to grow, they have become a major pollutant due to farm waste and fertilizer runoff. Municipal and industrial waste discharges contribute their fair share of toxins as well. There’s also all the random junk that industry and individuals dump directly into waterways.

Ocean water

Eighty percent of ocean pollution (also called marine pollution) originates on land—whether along the coast or far inland. Contaminants such as chemicals, nutrients, and heavy metals are carried from farms, factories, and cities by streams and rivers into our bays and estuaries; from there they travel out to sea. Meanwhile, marine debris—particularly plastic—is blown in by the wind or washed in via storm drains and sewers. Our seas are also sometimes spoiled by oil spills and leaks—big and small—and are consistently soaking up carbon pollution from the air. The ocean absorbs as much as a quarter of man-made carbon emissions.

Point source

When contamination originates from a single source, it’s called point source pollution. Examples include wastewater (also called effluent) discharged legally or illegally by a manufacturer, oil refinery, or wastewater treatment facility, as well as contamination from leaking septic systems, chemical and oil spills, and illegal dumping. The EPA regulates point source pollution by establishing limits on what can be discharged by a facility directly into a body of water. While point source pollution originates from a specific place, it can affect miles of waterways and ocean.

Nonpoint source

Nonpoint source pollution is contamination derived from diffuse sources. These may include agricultural or stormwater runoff or debris blown into waterways from land. Nonpoint source pollution is the leading cause of water pollution in U.S. waters, but it’s difficult to regulate, since there’s no single, identifiable culprit.

Transboundary

It goes without saying that water pollution can’t be contained by a line on a map. Transboundary pollution is the result of contaminated water from one country spilling into the waters of another. Contamination can result from a disaster—like an oil spill—or the slow, downriver creep of industrial, agricultural, or municipal discharge.
