In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators – absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. How well a room absorbs sound is quantified by the effective absorption area of the walls, also named total absorption area.

transcending concern means the very existence of earth is endangered. earlier the people were worried about their on existence but now their problem is more serious. the natural resources of the earth are eroding fast and the planet is likely to be extinct so human must conserve the planet.

transcending concern – a concern that surpasses generation, boundaries. It is not only about the present but also about future; not only about people but also about the planet.

Due to the insensitive exploitation by humans for their survival and development, the earth has lost almost all its vital/important resources. With drying rivers, depleting and polluted environment and deteriorating forests and greenery, the earth is now breathing hard for its survival and thus it is an ailing planet.

There are four principal biological systems of the earth. These systems are fisheries, forests, grasslands and croplands. In addition to supplying our food, these four systems provide virtually all the raw material for the industry.

They form the foundation of the Global economic system. They supply us food. They all provide all the raw materials for industry accept minerals. Human demands on these systems are increasing to a point where there productivity is impaired .

Examples of biological systems at the macro scale are populations of organisms. On the organ and tissue scale in mammals and other animals, examples include the circulatory system, the respiratory system, and the nervous system.

The excessive demand results in deterioration and depletion of these resources. A country where protein is consumed on a large scale, over-fishing is common, which leads to the collapse of fisheries in that area. Grasslands have been turned into deserts and production of crops is decreasing.

The earth’s principal biological systems are being depleted by excessive use. Over . fishing is quite common. Forests are being cut to obtain firewood for cooking.

There are four principal biological systems of the earth. They are fisheries, forests,grasslands and croplands. They form the foundation of the Global economic system. Human demands on these systems are increasing to a point where there productivity is impaired.

Forests , grasslands , croplands and fisheries are the four systems that sustain life on earth. They are being cleared aggressively due to various reasons like fisheries are being cleared as people have become preotein conscious.

Our planet is under attack- here are 6 environmental threats facing it now:

• Climate change.
• Deforestation.
• Pollution.
• Loss of biodiversity.
• Oceanic dead zones.
• Overpopulation.
• Over-fishing.

Lester R. Brown, there are four principal biological systems of the earth. These systems are fisheries, forests, grasslands, and croplands. However, due to the increasing demand of human beings to such an ‘unsustainable’ extent, the productivity of these systems is being hampered.

What causes the depletion of our natural resources?

• Overpopulation.
• Overconsumption and waste.
• Deforestation and the Destruction of Ecosystems leading to loss of biodiversity.
• Mining of Minerals and Oil.
• Technological and Industrial Development.
• Erosion.
• Pollution and Contamination of resources.

Answer: Sustainable development can be defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

10 Solutions for Natural Resource Depletion

1. Make Electricity Use More Efficient.
2. Use More Renewable Energy.
3. Promote Sustainable Fishing Rules.
4. Avoid Single-Use Plastics.
5. Drive Less.
6. Recycle More and Improve Recycling Systems.
7. Use Sustainable Agriculture Practices.
8. Reduce Food Waste.

The six natural resources most drained by our 7 billion people

1. Water. Freshwater only makes 2.5% of the total volume of the world’s water, which is about 35 million km3.
2. Oil. The fear of reaching peak oil continues to haunt the oil industry.
3. Natural gas.
4. Phosphorus.
5. Coal.
6. Rare earth elements.
