Legislation in the Philippines that regulates and protects the environment, covering various aspects like pollution and resource management.

Combined efforts of governments and businesses to address environmental issues through regulation, sustainability practices, and conservation.

Problems related to the degradation or pollution of the environment, impacting ecosystems, human health, and climate.

Three main approaches to managing resources: conservation, preservation, and utilization. Conservation aims to use resources sustainably, preservation focuses on protecting resources from harm, and utilization prioritizes using resources for economic benefit.

The Philippine government mainly utilizes its natural resources, often prioritizing economic development over conservation or preservation. This approach can lead to environmental degradation in the long run.

Businesses employ various strategies to manage their resources, including:

1. Sustainability: Addressing environmental and social impacts
2. Social Responsibility: Acting ethically and considering stakeholders
3. Circular Economy: Reusing and recycling materials to minimize waste
4. Greenwashing: Misleading marketing to portray a company as environmentally friendly
5. Stakeholder Engagement: Collaborating with stakeholders on environmental and social issues
6. Environmental Compliance: Adhering to environmental regulations

The Philippines has various environmental laws, such as the Clean Air Act or the Wildlife Act. These laws aim to protect and conserve the environment, but enforcement and effectiveness can vary.

The Philippine Environmental Policy reflects a mix of social and state ethics. It promotes sustainable development while prioritizing economic growth, sometimes emphasizing state control over resource management rather than individual or corporate responsibility.

Tiny particles in the air can harm developing fetuses, leading to infant deaths, birth defects, and functional problems.

Chemicals like benzene, arsenic, and asbestos released by factories and vehicles cause serious health issues, including cancer, birth defects, and organ damage.

Lead, found in gasoline, paint, and coal, is highly toxic, especially to children. It can cause mental retardation, seizures, and damage to kidneys and blood.

Acid rain forms when pollutants like sulfur dioxide and nitrogen oxides combine with water vapor in the air.

The pH scale measures how acidic or basic a substance is. Lower numbers mean higher acidity.

Acid rain can be more acidic than vinegar, harming plants, animals, and water sources.

Burning fossil fuels releases pollutants that cause acid rain, impacting both the environment and our health.

Different products obtained by breaking down crude oil through refining processes, each having specific uses, such as gasoline for vehicles, naptha for the petrochemical industry, and bunker fuel for ships and power stations.

Oil spills have devastating effects on the marine environment, causing immediate death through smothering, long-term developmental defects, and harm to seabirds due to oil's impact on their plumage.

Oil tankers, after delivering crude oil, must fill their empty tanks with seawater for stability. However, they are not allowed to discharge this oil-contaminated water at loading terminals and often do so at sea, creating harmful oil slicks.

Human activities release toxic industrial and radioactive wastes into the sea, adding to naturally occurring radioactivity. These contaminants pose significant risks to marine life, especially those that accumulate and concentrate the wastes.

The accumulation of radioactive wastes by marine organisms, like algae and bottom-dwelling fish, can lead to genetic and health problems, highlighting the threat posed by radioactive contamination.

Plastic pellets and fragments, often found in beaches worldwide, indicate widespread plastic pollution in the oceans. This arises from accidental spills and deliberate dumping, posing dangers to marine life.

Plastic pollution in the ocean stems from unintentional spills and deliberate dumping, indicating a lack of responsible waste management and a need for better control of plastic waste.

Plastic pollution threatens marine life through ingestion and entanglement, harming individual organisms and disrupting marine ecosystems.

Effective plastic waste management is crucial to prevent pollution and protect marine life. This involves reducing plastic usage, recycling, and proper disposal, to curb the harmful flow of plastic into the oceans.

Burning fossil fuels like coal, oil, and natural gas releases carbon dioxide (CO2) into the atmosphere, contributing to climate change.

Cutting down trees removes their ability to absorb CO2 from the atmosphere, increasing levels of this greenhouse gas.

A monitoring station in Hawaii that measures CO2 levels in the atmosphere, showing a steady increase since 1958.

Rising CO2 levels in the atmosphere contribute to global warming and climate change, affecting weather patterns and ecosystems.

Methane (CH4), another greenhouse gas, comes mainly from biological sources, like livestock and waste, but some also from fossil fuels.

Human activities can be adjusted to decrease CO2 emissions, helping to stabilize or reduce greenhouse gas concentrations in the atmosphere.

A gas in the atmosphere that traps heat from the sun, contributing to global warming and climate change.

Long-term changes in global weather patterns, including rising temperatures, extreme weather events, and sea level rise.

The process plants use to convert sunlight, water, and carbon dioxide into food (sugar) and oxygen.

The natural process where greenhouse gases trap heat from the sun, keeping Earth warm enough for life. However, too much greenhouse gas can lead to global warming.

As global temperatures rise, diseases currently limited to warm areas may spread to new regions, potentially affecting more people.

Diseases spread by insects like mosquitoes, potentially becoming more common with warmer temperatures.

Overgrowth of algae, often triggered by warm temperatures and pollution, which can lead to disease outbreaks.

Climate change alters where animals and plants can live, affecting their spread and populations.

Warmer temperatures thaw permafrost in tundra regions, allowing trees from warmer areas to move in.

Climate change leads to less snow in mountains and earlier snowmelt, impacting ecosystems.

Coral reefs are at risk due to warmer waters and ocean acidification, making it hard for them to grow.

Rising sea levels threaten low-lying islands and coastlines, causing flooding and erosion.

Climate change affects crop production, potentially impacting food supply.

Changes in climate affect various aspects of our planet, including disease spread, ecosystems, and agriculture.

Governments directly set environmental standards like limits on pollution or resource use. They enforce these with laws and penalties for violators.

Managing natural resources in a way that is morally responsible and sustainable, considering future generations.

These are the COMBINED efforts of governments and businesses to address environmental issues through laws, sustainability, and conservation.
