The dividing line between natural and artificial resources is unclear. Hydropower is not a natural resource, as people use turbines to convert energy from moving water. Oil and iron ores are natural, but must be processed to make them usable in refined petroleum and steel. Nuclear energy comes from metallic nuclear fuels such as fissile uranium and plutonium, but natural rocks require engineering work to transform them into these nuclear fuels. Most natural resources are limited. This means that they will eventually run out. An eternal resource has an endless offer. Some examples of perpetual resources are solar, tidal and wind energy. [1] There may be a limit to the amount that can be taken on a given day or year, but this amount can be taken again the next day or the following year. Non-perpetual resources include fossil fuels such as oil, coal, etc.[2] They have a limit on use. The demand for resources can change with new technologies, new needs and new economies (e.g. B, changes in resource costs).
Some materials can be completely out of order when people don`t want them anymore. The demand for many natural resources is very high, but the availability of some, such as precious metals, is very low. A natural resource is what people can use that comes from the natural environment. Examples of natural resources include air, water, wood, oil, wind, natural gas, iron and coal. Renewables are the fastest growing energy source and, by 2040, are expected to account for a share of energy production equivalent to that of coal and natural gas, or about 15% of global energy consumption. [6] Natural resources such as sunlight, wind, rain, tides, waves, and geothermal energy provide renewable energy that does not require large amounts of fresh water. [18] The United States is the world`s largest producer of natural gas, but we consume even more natural gas than we produce. As of June 2015, the United States produced 89.5 billion cubic feet of natural gas per day. [5] Different places have different natural resources. If people don`t have a particular resource they need, they can either replace it with another resource or trade with another country to preserve the resource.
People sometimes fought for them (e.g., spices, water, farmland, gold, or oil). The energy industry is the third largest industry in the United States, but in 2014, energy production in the United States covered only about 89% of the country`s consumption needs. [2] U.S. energy consumption comes from the following sources: 35% oil, 28% natural gas, 18% coal, 10% renewable energy and 8% nuclear. [3] The responsible use of the Earth`s natural resources is essential to our long-term security and sustainability. At present, the United States currently accounts for only 4.4% of the world`s population, but 18% of the world`s total primary energy consumption. [1] Non-renewable resources such as coal and natural gas take millions of years to recover for the planet to recover, and renewable resources must be replaced when used. The scarcity of these resources can have both economic implications and risks to U.S.
security. The responsible use of renewable resources and the reuse of products made from non-renewable energies such as recycled steel and plastic ensure our independence and can reduce greenhouse gas emissions from fossil fuels. [7] Natural resources are those that the planet provides without human intervention. They are vital for survival, but if consumed faster than their natural regeneration, as is currently the case, they can be depleted. Next, we review the consequences and possible solutions to this problem. There are two types of natural resources: renewable and non-renewable. The former are inexhaustible, like solar radiation, or their renewal is relatively rapid, as is the case with biomass. Non-renewable resources are those that exist in nature on a limited scale, as their regeneration requires the passage of many years, such as minerals and fossil fuels – oil, natural gas and coal.

So people are protecting resources. If they can`t get clean water, people can get sick; If there is not enough wood, the trees will be cut down and the forest will disappear over time (deforestation); If there are not enough fish in a sea, people can starve to death. .
