Study Notes
Climate Change and Resources
- High greenhouse gas emissions and unabated global warming may lead to catastrophic consequences
- Renewable natural resources include those that can be replenished naturally over time
- Fossil fuel is a non-renewable resource, meaning it takes millions of years to form and cannot be replenished quickly
Ecosystem Services
- Plants, animals, and microorganisms provide ecosystem services, including climate regulation and water purification
- Ecosystem services also provide benefits such as food, water, and air
Water Resources
- Only 2.5% of the Earth's water is available for use
- Malaysia sources most of its water from rivers and lakes
- The Bakun Dam is the biggest dam in Southeast Asia
- Hydropower contributes 17.4% of Malaysia's energy
Food and Agriculture
- Rice is the main source of food for Malaysians and many other Asian societies
- The FAO estimates that there are over 30,000 edible plant species, but only 150 are cultivated as food
Forests and Habitats
- Peat swamp forests are a unique habitat characterized by acidic and oxygen-poor conditions
- A forest is defined as an area of land dominated by trees and other woody vegetation
- Mangroves are characterized by the presence of Rhizophora trees and are found in coastal areas
- Estuaries are habitats where freshwater rivers meet the sea
Conservation and Protected Areas
- Only about 1.3% of Malaysia's waters are designated as marine protected areas (MPAs)
- Marine parks in Peninsular Malaysia and the Federal Territory of Labuan cover a total area of 13,433 hectares
- In Sarawak, marine protected areas cover a total area of approximately 11,484 hectares
