What are the problems caused by non renewable resources and how can we conserve them?

Non-renewable resources are those that cannot be regenerated in a reasonable enough time frame to be reused by human beings. Some examples of non-renewable resources include coal, petroleum, natural gas, etc. Since it takes millions of years for these resources to form, they are in a limited quantity. If our consumption patterns continue, we are likely to run out of them soon. Since our energy requirements are mostly fulfilled by such resources, we will be in trouble. Another, perhaps more significant concern with the use of such resources, is the generation of greenhouse gases such as carbon dioxide and methane. The increased concentration of these gases in our atmosphere has been correlated to an increase in global temperature, commonly referred to as global warming.

The conservation of these resources is possible by either replacing them, minimizing their consumption and/or using such resources more efficiently. Renewable resources such as solar energy, wind energy, hydropower, etc., can be used to replace non-renewable resources. We can also use more efficient energy generation practices and more efficient devices to minimize the consumption of non-renewable resources.

Hope this helps.
