The Philippines is an archipelago that comprises 7,641 islands with a total land area of 300,000 square kilometers (115,831 sq mi). It is the world's fifth largest island country. The eleven largest islands contain 95% of the total land area. The largest of these islands is Luzon at about 105,000 square kilometers (40,541 sq mi). The next largest island is Mindanao at about 95,000 square kilometers (36,680 sq mi). The archipelago is around 800 kilometers (500 mi) from the Asian mainland and is located between Taiwan and Borneo.
Manila Bay is a natural harbor that serves the Port of Manila, in the Philippines. Strategically located around the capital city of the Philippines, Manila Bay facilitated commerce and trade between the Philippines and its neighboring countries, becoming the gateway for socio-economic development even prior to Spanish occupation. With an area of 1,994 km2 (769.9 sq mi), and a coastline of 190 km (118.1 mi), Manila Bay is situated in the western part of Luzon and is bounded by Cavite and Metro Manila on the east, Bulacan and Pampanga on the north, and Bataan on the west and northwest. Manila Bay drains approximately 17,000 km2 (6,563.7 sq mi) of watershed area, with the Pampanga River contributing about 49% of the freshwater influx. With an average depth of 17 m (55.8 ft), it is estimated to have a total volume of 28.9 billion cubic meters. Entrance to the bay is 19 km (11.8 mi) wide and expands to a width of 48 km (29.8 mi). However, width of the bay varies from 22 km (13.7 mi) at its mouth and expanding to 60 km (37.3 mi) at its widest point.
Laguna de Bay, also known as Laguna Lake, is the largest lake in the Philippines. It is located southeast of Metro Manila, between the provinces of Laguna to the south and Rizal to the north. A freshwater lake, it has a surface area of 911–949 km², with an average depth of about 2.8 meters and an elevation of about one meter above sea level. The lake is shaped like a crow's foot, with two peninsulas jutting out from the northern shore and filling the large volcanic Laguna Caldera. In the middle of the lake is the large island of Talim.
The Pasig River is a water body in the Philippines that connects Laguna de Bay to Manila Bay. Stretching for 25.2 kilometers (15.7 mi), it bisects the Philippine capital of Manila and its surrounding urban area into northern and southern halves. Its major tributaries are the Marikina River and San Juan River. The total drainage basin of the Pasig River, including the basin of Laguna de Bay, covers 4,678 square kilometers (1,806 sq mi).
Executive departments are the largest component of the executive branch of the government of the Philippines. These departments comprise the largest part of the country's bureaucracy.
Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there. The majority of this waste (80%) comes from land-based activity, although marine transportation significantly contributes as well. It is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide.Since most inputs come from land, either via the rivers, sewage or the atmosphere, it means that continental shelves are more vulnerable to pollution. Air pollution is also a contributing factor by carrying off iron, carbonic acid, nitrogen, silicon, sulfur, pesticides or dust particles into the ocean. The pollution often comes from nonpoint sources such as agricultural runoff, wind-blown debris, and dust. These nonpoint sources are largely due to runoff that enters the ocean through rivers, but wind-blown debris and dust can also play a role, as these pollutants can settle into waterways and oceans. Pathways of pollution include direct discharge, land runoff, ship pollution, bilge pollution, atmospheric pollution and, potentially, deep sea mining.
The Metropolitan Manila Development Authority is a government agency of the Philippines responsible for constituting the regional government of Metro Manila, comprising the capital city of Manila, the cities of Quezon City, Caloocan, Pasay, Mandaluyong, Makati, Pasig, Marikina, Muntinlupa, Las Piñas, Parañaque, Valenzuela, Malabon, Taguig, Navotas and San Juan, and the municipality of Pateros.
Today, environmental problems in the Philippines include pollution, mining and logging, deforestation, threats to environmental activists, dynamite fishing, landslides, coastal erosion, biodiversity loss, extinction, global warming and climate change. Due to the paucity of extant documents, a complete history of land use in the archipelago remains unwritten. However, relevant data shows destructive land use increased significantly in the eighteenth century when Spanish colonialism enhanced its extraction of the archipelago's resources for the early modern global market. The Philippines is projected to be one of the most vulnerable countries to the impacts of climate change, which would exacerbate weather extremes. As the Philippines lies on the Pacific Ring of Fire, it is prone to natural disasters, like earthquakes, typhoons, and volcanic eruptions. In 2021, the Philippines ranked the fourth most affected country from "weather-related loss events", partly due to the close proximity of major infrastructure and residential areas to the coast and unreliable government support. One of the most devastating typhoons to hit the archipelago was Typhoon Haiyan, known locally as Yolanda, in 2013 that killed 6,300 people and left 28,689 injured. Congress passed the Clean Air Act of 1999, the Philippine Clean Water Act of 2004, the Climate Change Act of 2009 to address environmental issues. The country is also a signatory to the Paris Agreement. However, research has found that outside of cities, the general public doesn't feel equally informed. Environmental activists and land defenders, consisting mostly of Indigenous communities who have been attempting to bring attention to the environmental issues in the country have been met with violence or murder. As a result, the Philippines has been ranked one of the most dangerous places in the world for environmental activists.
The Laguna Lake Development Authority (LLDA), one of the attached agencies of the Department of Environment and Natural Resources (DENR), is responsible for the preservation, development, and sustainability of Laguna de Bay and its 21 major tributary rivers.
The Philippines' water supply system dates back to 1946, after the country declared independence. Government agencies, local institutions, non-government organizations, and other corporations are primarily in charge of the operation and administration of water supply and sanitation in the country.
The Pasig River Ferry Service (PRFS) is a public water bus service based in Metro Manila, the Philippines. It is currently the only water-based transportation service in Metro Manila that cruises the length of the Pasig River and Marikina River, passing through the cities of Manila, Makati, Mandaluyong, Pasig, Marikina, and Taguig.
The Manggahan Floodway is an artificially constructed waterway in Metro Manila, Philippines. The floodway was built in 1986, with the cost of 1.1 billion pesos, in order to reduce flooding along the Pasig River during the rainy season, by diverting the peak water flows of the Marikina River to Laguna de Bay, which serves as a temporary reservoir. In case the water level on the lake is higher than the Marikina River, the floodway can also reverse the flow.
Pollution is an environmental issue in Canada. It has posed health risks to the Canadian population and is an area of concern for Canadian lawmakers. Air, water and soil pollution as well as the associated health effects are prominent points of contention in modern Canadian society.
The Pasig River Rehabilitation Commission was a state commission in charge of the rehabilitation of the Pasig River. The commission served for 20 years, from 1999 until its dissolution by President Rodrigo Duterte in November 2019. The body's powers and functions were transferred to the Manila Bay Task Force and the Department of Environment and Natural Resources.
The Pasig River is a river in the Philippines running right through the heart of Manila. It flows from Laguna de Bay to Manila Bay through a length of 26 kilometers (16 mi) and an average of 50 meters (160 ft) in width. The average depth of the river in around 4–6 meters (13–20 ft). The river runs through some of the most populated areas in the Philippines.
The Pasig River Expressway (PAREX) is a proposed elevated expressway in Metro Manila, Philippines that will skirt the banks of the Pasig River and connect the cities of Manila, Mandaluyong, Makati, Pasig, Taguig and the municipality of Taytay. The expressway is being proposed to alleviate east-west traffic congestion in Metro Manila. It is a joint venture between the Philippine National Construction Corporation and the San Miguel Corporation. The project broke ground on September 24, 2021, while construction of the expressway has yet to start pending the approval of its Environmental Compliance Certificate (ECC).
