is the degradation of Earth's land surfaces often caused by human activities and their misuse of land resources. It occurs when waste is not disposed properly. Health hazard disposal of urban and industrial wastes, exploitation of minerals, and improper use of soil by inadequate agricultural practices are a few factors.

Urbanization and industrialization are major causes of land pollution. The Industrial Revolution set a series of events into motion which destroyed natural habitats and polluted the environment, causing diseases in both humans and other species of animals.

 Some of the major contributors to land

pollution include:Oil refineriesHuman sewageMiningLitteringHerbicidesIndustrial factoriesDeforestationConstruction debrisOvercrowded landfillsChemical and nuclear plantsOil and antifreeze leaking from cars

one family a day can make two – three plastics of trash in a day. There are around eighty million Filipinos in our country; therefore, 16 million families exist, creating 32 million plastics of trash in a day. Can you imagine where all those waste will go? This is the very reason why the Philippines cannot help but have dumpsites where all our mountains of trash set off. One popular example for this is the Smokey Mountain. These dumpsites are not healthy for these are where germs and bacteria love to stay. Flies and mosquitoes are very much attracted in these kinds of areas as well. These also create smells that are not good for the body. There are many people living nearby these sites and unfortunately, they are the ones greatly affected and they are left with no choice.

Aside form Metro Manila , the city of Meycauayan and the town of Marilao in Bulacan province share a slot in the list of the world’s 30 most polluted places dubbed as the “Dirty Thirty” . Industrial waste is haphazardly dumped into the Marilao, Meycauayan and Obando. These places were polluted due to wastes received from tanneries, gold and precious metals refineries ,the largest lead smelter in the Philippines, and numerous municipal dumpsites

The term "street foods" describes a wide range of ready-to-eat foods and beverages sold and sometimes prepared in public places, notably streets.

The most common Philippine street foods include fried squidballs, fishballs, kikiam—a type of processed chicken, which is served on a stick, with a variety of dipping sauces.

Environmental Health RisksRapid population growth and urbanization

have serious environmental and health implications. With the emergence of modern environmental hazards (e.g., improperly disposed hazardous substances from industries and households, vehicular and industrial emissions) and the persistence of traditional hazards (e.g., lack of access to fundamental resources such as safe water, sanitation and housing).

Page 10: Land Pollution (Power Point)

Filipinos face the burden of both communicable diseases, which are closely linked with traditional hazards, and diseases, which are associated with modern hazards. Under these circumstances, impoverished communities that have yet to acquire the basic needs essential for healthy living like water, food, shelter and sanitation facilities experience greater difficulties and risks.

Food SanitationFood-borne diseases are usually caused by

infectious organisms like viruses, bacteria and parasites and, in most instances, manifest as diarrhea. These diseases are transmitted from person to person by means of soiled hands and food contaminated by human waste through the oral-fecal route. The incidence of food-borne diseases peaks during the rainy season and is usually high in areas where sanitation and hygienic practices are poor.

• Although improvements in morbidity and mortality rates for food-borne diseases have been noted, the burden of diarrheal diseases is still high and reflects poor access to safe water supply and sanitation facilities by the more susceptible population groups. While the number of water and sanitation facilities has increased, the availability of these facilities in the rural areas and among the poorer sector of the urban population has not significantly changed.

An emerging issue relative to food safety in the country is the issue on street foods. With the rapid urbanization of the country and the fast-paced lifestyle of the urban population, comes its inevitable popularization. In a study conducted by Barth, it was found that the purchase of non-household food preparations accounted for about 30 percent of all food expenditures. These purchases were usually from the immediate neighborhood selling street foods. In a study conducted by the Food and Nutrition Research Institute (FNRI), selected street foods have been found to have significant nutritional value, but the public has to be guided on the choices and be educated on the danger that these foods can pose to health if they are not prepared well. Several other studies have shown the presence of microorganisms in the commonly vended street foods.

• The problem at the moment is that there is no local standards upon which microbial levels in street foods may be assessed and even provide basis for monitoring efforts.

• There has to be a nationwide attempt to require registration or licensing of street food vendors. The street food industry needs a recognized body that will coordinate efforts by various agencies relative to this sector and at the same time serve as anchor in policy formulation and provision of technical assistance.

• Training courses provided by LGUs to street food vendors have yet to be reviewed and regulated. The government has already recognized the economic contributions of this informal sector. It needs to come up with a comprehensive package of services to address problems and uplift its status as a major source of food for people.

• The occurrence of food-related issues with the recent emergence of diseases like the avian influenza and bovine spongiform encephalopathy (BSE) and the perennial presence of food and water-borne diseases in the top ten causes of morbidity and infant mortality prompted the DOH to create in 2003 the Food Safety Committee.

Philippine Street Foods• During breaktime from work, you can see people

in all walks of life who are in tight budget are crowding food stalls along the main streets in many cities in the Philippines (just like any crowded cities in Asia or other parts of the world) to eat street foods. It varies from viands or entree, snacks and finger foods. Street foods are the alternative food if you want to be a spend thrift. The taste of the food can be compared to the food being prepared at famous fast food and restaurants. The only difference is the price; it's more cheaper. Tourists, local and foreign, are also enjoying this kind of food setting. Eating along the street, can be relaxing, but there are also dangers that can cause health problems for me and you.

Eating food along the street is dangerous• Now that many pollutants are everywhere,

eating street food is dangerous. Even in many progressive countries, street vendors are selling newly-cooked food that lure the palate or taste buds of bystanders. I didn't have any grudge with the vendors but authorities should issue health warnings and certificate to ensure people of the safeness of the food they are selling. Even we're selling food at home, we must ensure the safety of the ingredients we are using.Food Poisoning can cause fatal effects or even death to people who are at risk when eating street food. Street vendors serve their food hot but are we sure it's safe?
