Study Notes
State of Local and International Environment
- The Philippines is recognized as one of the megadiverse countries, housing a significant number of Earth’s species and high levels of endemism.
- In biodiversity rankings, the Philippines holds second place in fish, fifth in plants, trees, and mammals, and eighth in reptiles.
- While global discoveries yield one new species per family annually, the Philippines reports five to six discoveries per taxa each year.
- The Philippines is the "Center of Marine Biodiversity," surpassing the Great Barrier Reef, with extensive coral reefs where 488 out of 800 known species globally are found.
- Geographic diversity contributes to rich water resources: 421 rivers, over 69 natural lakes, and significant freshwater swamps.
- The country has vast agricultural land, with 14.2 million hectares classified as alienable and disposable land, alongside 13 million hectares of agricultural land.
- Mineral resources are abundant, making the Philippines the fifth mineralized country worldwide.
Environmental Crisis in the Philippines
- Despite its rich forests, Philippine forest cover has declined from 70% in 1909 to 18.3% in 1999, continuing to reduce at an average rate of 2% annually, with 25.9% cover reported in 2018.
- Marine biodiversity is threatened by habitat loss, overfishing, and pollution, causing displacement and endangerment of various species due to the destruction of vital ecosystems.
- Freshwater scarcity is a pressing issue, with many areas in Southeast Asia suffering from significant contamination, posing challenges to clean water access.
Environmental Challenges in Africa
- Africa faces severe climate impacts, including droughts, floods, and storms, worsening health and economic conditions.
- The continent is expected to warm up to 1.5 times faster than the global average, complicating agricultural productivity of key crops by 2050.
- Water scarcity issues arise from multiple factors, making it difficult to isolate the direct impacts of climate change.
Climate Change in Antarctica
- Recent record-high temperatures in Antarctica indicate significant climate change implications, including the collapse of ice shelves, impacting global water resources.
Climate Change Impacts in the United States
- Different regions in the U.S. face unique climate change challenges:
- Northeast: Heatwaves and heavy downpours threaten infrastructure and agriculture.
- Northwest: Changes in streamflow and increased wildfires disrupt water supply and ecosystems.
- Southeast: Sea level rise presents ongoing threats to the economy and environment.
- Midwest: Extreme weather affects infrastructure, health, and agriculture.
- Southwest: Heat, droughts, and flooding pose serious concerns for water and health.
Climate Change in Australia
- Australia is predicted to experience dangerous consequences from climate change, including natural disasters and widespread forced migration.
- Political indecision has hindered responses to climate impacts, contributing to increased vulnerability.
Environmental Degradation
- Environmental degradation refers to the depletion of resources like air, water, and soil due to human activities and natural disturbances.
- Major causes include pollution, overpopulation, deforestation, overexploitation, and natural disasters.
Causes of Environmental Degradation
- Pollution: Contaminating the environment via land, water, air; includes light and sound pollution.
- Overpopulation: Exceeds ecological capacity, leading to shortages of food, water, and energy.
- Deforestation: Permanent loss of forests; approximately 18 million acres lost annually worldwide.
- Overexploitation: Unsustainable use of renewable resources, leading to depletion and ecosystem collapse.
- Natural Causes: Events like earthquakes and hurricanes that disrupt ecosystems.
