I really want to go on an around-the world- trip because I will see a lot of interesting things, it will broaden my mind. I will gain more knowledge about the world, experience different cultures. I think the country I want to go the most is Singapore.

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 PollutionGroundwater
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.

Reasons for making environment-friendly products are:
- Protecting the environment: Making environment-friendly products helps to protect the environment by reducing negative impacts on the environment, such as greenhouse gas emissions, pollution, and resource depletion.
- Protecting human health: Environment-friendly products are typically made from natural, non-toxic ingredients that are safer for people to use.
- Saving money: Environment-friendly products can often be more cost-effective over the long-term than conventional products.
Reasons for starting a competition on making environment-friendly products are:
- Promotes creativity and innovation: By creating a competition on making environment-friendly products, students will be encouraged to come up with innovative and creative ideas for products that are both sustainable and eco-friendly.
- Raises awareness about environmental issues: The competition can help raise awareness about the importance of environmental sustainability and environmental protection.

I agree with all the ideas.
- I agree with the petition “Say NO to orca shows”.
Because keeping orcas in small tanks and training them to perform tricks is cruel and inhumane. Moreover, they are highly intelligent and social animals that require a large and complex environment to thrive.
- I agree with the petition “SAVE sea turtles on CON DAO island”.
Because sea turtles play an important ecological role in marine ecosystems, they are valuable and endangered species that deserve protection. Commercial hunting and pollution are serious threats to sea turtle populations and their natural habitat.
- I agree with the petition “We love ugly fruit!”.
Because I believe that food waste contributes to environmental and social issues. Rejecting imperfect fruits and vegetables is wasteful, meanwhile, selling ugly produce at a lower price can reduce food waste and make healthy food more accessible to low-income households.
