A savanna or a grassland biome is home to a number of natural resources, including water, livestock and lumber in tropical savannas, and coal, oil, wheat, gas, oats and livestock in temperate savannas. Some grasslands are also found to have mineral deposits, such as iron, mercury, nickel and uranium.
Northern Australia is home to the largest savanna in the world. It stretches 1,250 miles across the continent and accounts for more than a quarter of all the remaining grasslands that once thrived over Asia, Africa and South America. The Australian tropical savanna is rich in metal deposits, making it the largest money generator in that part of the country. Metal resources mined in the tropical grassland include silver, gold, tin, nickel, copper, bauxite, magnesite, uranium and manganese. Phosphate rock, diamonds, limestone and silica are also mined in the savanna, as are petroleum and coal.
The vast expanse of grassy vegetation in eastern South Africa supports nearly 2 million herbivorous mammals and over 500 species of birds. The grassy landscape is also the location of large deposits of gold and coal. The Eurasian and North American savannas are known for having shale formations of petroleum and natural gas. The ever-increasing human habitation, extensive mining and natural energy explorations threaten to irreversibly modify and damage the natural ecosystem of savannas around the world.Learn More
Coal is formed in a swampy depositional environment that includes the remains of trees and shrubs. This swampy environment is able to bury plant life quickly before it rots. Once buried, the plant life is heated and compressed to form coal.Full Answer >
Examples of biodegradble things are paper, cotton, human and solid waste. When disposed, biodegradable materials are broken down by microorganisms and other living things in a reasonable time period.Full Answer >
Deforestation can generate income for farmers, land developers and national economies, but deforestation can have a negative impact on local and global ecologies and ecosystems. The population in most countries is increasing, which puts pressure on local economies to produce more food or clear more land for urban development priorities such as housing and commerce. Cutting down forests not only generates income from the sale of timber, but also clears land for use in development. On the other hand, forests are vital parts of local and global ecosystems. Cutting down forests, especially jungles and rain forests, often threatens species of wildlife and ultimately contributes to dangerous trends such as global warming.Full Answer >
Exhaustible resources, or nonrenewable resources, include fossil fuels, mineral ores and uranium. Use of these natural resources leads to their depletion. Inexhaustible resources include solar, wind and hydroelectric power, which naturally replenish, or timber and corn, which can be replenished through proper management.Full Answer >
