Question

How can the resources be managed and conserved?

Answer 1

Natural resources are materials or substances from the Earth that are utilized to support life and meet people's needs. Any natural substance that humans use is often considered a natural resource. Oil, coal, gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil, water, plants, animals and fossil fuels.

Complete answer:
Natural resources are accustomed to make food, fuel and raw materials for the production of goods. Every food that people eat comes from plants or animals. Natural resources like coal, gas and oil provide heat, light and power. Natural resources are also the raw materials for creating products that we use every day from our toothbrush and lunch box to our clothes, cars, televisions, computers and refrigerators. There are two types of resources, Renewable and non-renewable resources.
Renewable resources are those natural resources such as trees, water, sun and wind that can be replenished at about an equivalent rate at which they're used. Renewable resources, however, are often depleted if not properly managed or conserved. Nonrenewable resources are those natural resources that are depleted more quickly than they can regenerate. Fossil fuels like oil and gas were formed over many years. Extracting, processing and using natural resources can cause environmental problems such as: air, land and water pollution; disruption or destruction of ecosystems; and a decrease in biodiversity.
For example, carbon dioxide – which is produced from burning coal, oil and gas (fossil fuels) – may be a critical greenhouse gas. Greenhouse gases absorb and retain heat from the sun. Examples of greenhouse gases include methane, ammonia, sulfur dioxide and certain chlorinated hydrocarbons. Many scientists believe that the build from greenhouse gases within the atmosphere can cause global climate change. Resource recovery may be a practice that conserves natural resources by extracting material (e.g., paper, glass, aluminum and steel) from the waste stream and recycling it into other materials or using it to supply energy. There are some ways each of us can conserve natural resources. Reducing our consumption – that's reducing what we buy, buying products with less packaging, reusing what we will, composting and recycling – is one among the simplest ways.

Note:
Recycling or reuse of 2,000 pounds of paper saves 7,000 gallons of water and 380 gallons of oil. Using recovered aluminium cans saves 95 percent of the energy required to make the same amount of aluminium from bauxite ore. For every ton of recovered glass (cullet) used to make new glass, more than 2,000 pounds of raw materials are saved. For every ton of recovered glass (cullet) used to make new glass, more than 2,000 pounds of raw materials are saved.
