Natural resources are derived from the environment. Biotic natural resources also include fossil fuels such as coal and petroleum which are formed from organic matter that has decayed. Abiotic: these resources come from non-living and non-organic material.

Plants/trees play a very important role in our life. They fulfil our food, fodder fuel, timber, fibre and medicinal needs. Plants/trees are helpful in mitigation of environmental pollution. Trees are helpful in the maintenance of ground water level.

Natural resources are materials created in nature that are used and usable by humans. They include natural substances (e.g., soil, water) and energy supplies (e.g., coal, gas) that serve to satisfy human needs and wants (Barsch and Bürger 1996; Minc 1976).

The sun is a natural, renewable resource.

Natural resources are materials from the Earth that are used to support life and meet people’s needs. Any natural substance that humans use can be considered a natural resource. Other natural resources are air, sunlight, soil and water. Animals, birds, fish and plants are natural resources as well.

Humans use natural resources for everything they do: for example, they use soil and water to grow food, wood to burn to provide heat or to build shelters, and materials such as iron or copper extracted from Earth to make cooking pans.

1. Water. Like soil, water is one of the most important natural resources for the existence of life. Fresh water is considered a renewable resource, but most of the water humans drink comes from groundwater sources that are being depleted faster than they can be replenished.

The truth is, any of the fossil fuels that are usually in the discussion, like oil and natural gas, probably won’t be running out for generations, if ever. Some resources are able to be recycled, and others can be recovered. So as our reserves dwindle down, they’ll just start becoming more expensive to produce.

Conclusion: how long will fossil fuels last? It is predicted that we will run out of fossil fuels in this century. Oil can last up to 50 years, natural gas up to 53 years, and coal up to 114 years. Yet, renewable energy is not popular enough, so emptying our reserves can speed up.

Technically speaking it is actually unlikely that we will ever ‘run out’ of oil. Oil, and all other fossil fuels are finite resources by their very nature, but as easier reservoirs of oil are exhausted other more complicated reservoirs become economically viable.

We will no longer need oil by 2050 — if we no longer need food, medicine, or transportation fuel. Petroleum is used for other purposes besides fuel — such as making drugs, heart valves, and other medical products.

Saturated (mostly animal and coconut oil), monounsaturated (olive oil), and polyunsaturated (omega-3 & -6 oils) fat are all associated with increase in new atherosclerotic lesions[4]. All kinds of oils, including olive oil, are found to contribute to arterial damage and also the progression of heart disease[5].

7 ways oil and gas drilling is bad for the environment

• Drilling disrupts wildlife habitat.
• Oil spills can be deadly to animals.
• Air and water pollution hurt local communities.
• Dangerous emissions contribute to climate change.
• Oil and gas development ruins pristine landscapes.
• Fossil fuel extraction turns visitors away.

What are the disadvantages of using crude oil?

• Oil is a non-renewable source of energy.
• Burning oil produces carbon dioxide gas.
• Burning oil can pollute the air.
• Much of our oil has to be imported and it is becoming more and more expensive as reserves reduce and imports increase.
