Environmental Issues

Waste Management .

What is waste management?

• Waste management involves the collection, transportation, treatment, and disposal of waste materials that aims to reduce the effects of waste on human health and the environment. Methods include recycling, composting, incineration, and landfilling.

Why is waste management important?

• Waste management is important because it protects the environment by reducing pollution and conserving resources. It also safeguards public health by preventing diseases from spreading and minimizing health risks from improper waste disposal.

Causes and Effects

Real World Examples

• Lebanon: garbage piled up on the streets

• Philippines: dumpsite fire

• Uganda: trash blocking drainage channels

• Germany, Sweden, Netherlands: Recycling programs (the collection and processing of materials like paper, glass, metals, and plastic to create new products, reducing waste and conserving resources

• Sweden, Denmark, Japan: Waste-to-energy (WtE) facilities convert municipal solid waste into electricity or heat through combustion, significantly reducing waste volume and generating renewable energy.

Current Efforts

• Circular Economy: most major industries have recently switched from a linear economy to a circular economy wherein products are designed for reuse, repair, and recycling, to maximize the lifespan of raw materials and minimize waste

• Composting: composting is another highly encouraged way of addressing the waste management issue; it is the natural way organic materials are recycled into fertilizers that enrich soil

Recommended Solutions

• Practicing the 3Rs

• Consumption awareness

• Joining coastal cleanups and other campaigns

Overpopulation .

What is overpopulation?

• Number of people exceeds the capacity of the environment

• Creation of waste and pollution that can degrade the environment

• Difficulty maintaining a healthy balance between human needs and resources

Effects

Environmental Consequences

• Resource depletion

  • Increase in demand for finite resources such as freshwater, fossil fuels, and arable land

  • Forests are cleared for agriculture, housing and industries, leading to deforestation and loss of biodiversity

  • Ex. an example is when there is overfishing in the oceans, which reduces the fish populations faster than can be reproduced

• Loss of biodiversity

  • Extinction of species

  • Ecosystems become imbalanced, reducing their ability to provide services like pollination, water purification, and climate regulation

  • Ex. coral reefs are losing biodiversity because of climate change and pollution, harming marine life and the communities that rely on them

• Climate Change

  • Increased carbon emissions from transportation, industries, and energy consumption

  • Acceleration in global warming and contribution to extreme weather patterns

  • Ex. overpopulation drives climate change by boosting fossil fuel demand, resulting in higher greenhouse gas emissions from transportation and energy use

• Water scarcity and soil degradation

  • Water shortages in many parts of the world

  • Over-extraction causes rivers and lakes ot be depleted

  • Over-farming, deforestation, and urban expansion lead to soil erosion, desertification, and loss of fertile land

  • Ex. the increase of agricultural demand and urban development, which over-extracts water resources and depletes soil nutrients through intensive farming practices

• Increased waste and pollution

  • More waste generation, overwhelming waste management systems

  • Plastic pollution, untreated sewage, and industrial waste contaminated land, water, and air, harming ecosystems and human health

  • Ex. rapid urbanization in densely populated areas often results in increased plastic waste, which clogs waterways and harms marine life, creating significant environmental challenges

Social Consequences

Economic Consequences

Real Word Examples

• With Kenya’s issue of overpopulation, there are informal settlements where millions live in slums with limited access to basic services

• USA shows how overpopulation can cause pollution and the rise of housing cost which ultimately leads to homelessness

• Due to Philippine’s overpopulation, economic pressure, housing shortage, and unemployment rate increases

• Overpopulation in Nigeria is affecting the country through urban overcrowding, strained healthcare and education systems which creates a huge impact for the younger ones

• India’s rapid population growth problem puts strain on the country’s resources, causing things like environmental degradation

• China is an example of overpopulation, (with one of the highest population right now with India) leading to the resource constraints of the country

• Mexico’s overpopulation leads to air pollution, water shortages, and infrastructure strain

Resource Depletion .

Brief Introduction

• Occurs when there is an exhaustion or reduction of natural resources

• Happens due to overconsumption and unsustainable use

• Natural resources are consumed faster than they can be replenished, leading to shortages

• Threatens the balance of the environment, economic stability, and human well-being

Key Concepts

• Environmental sustainability involves making responsible choices that ensure the long-term health of our planet

• Resource depletion is the effect of unsustainability, ultimately caused by the human person and their habits and activities (including but not limited to: deforestation, overfishing, urbanization, etc.)

• It is defined as the consumption of resources quicker than it can be restored

• Being aware of resource depletion is crucial because of its broad and harsh effects on the environment

• This issues puts various resources and ecosystems at risk which will make an impact on the future generations

Causes and Effects

Real-World Examples

• Deforestation in the Amazon Rainforest

• Overfishing in the Atlantic Ocean

• Oil depletion in the North Sea

• Deforestation in Palawan (losing 47,000 hectares annually leading to biodiversity loss and threatening habitats)

• Overfishing in Visayas and Mindanao (leading to lesser marine population contributing to the loss of multiple jobs)

Current Efforts

• Promoting and normalizing renewable energy (solar energy, biomass energy, wind power, geothermal energy, hydro energy)

• Policy, legislation, and regulation (governments must continue to enforce strict rules and regulations designed to lessen and promote certain practices to combat resource depletion) (ex. Banning single-use plastics, offering incentives)

• Various organizations and initiatives (ex. WWF, UNEP, The Pocketbook Agency’s paperless office movement, The Ecovillage movement)

Recommended solutions

• Promotion of sustainable tourism: limiting tourist numbers in vulnerable areas, and prioritizing local communities

• Shifting towards eco-friendly architecture: reducing energy consumption through green buildings built from eco-friendly materials, energy-efficient designs, and rooftop gardens

• Advancement of sustainable agriculture: utilizing biotechnology and developing new techniques that require less land, water, and the creation of healthy ecosystems
