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
