Natural Resources

Should we change the way we use non-renewable resources? We should focus on our renewable resources such as sunlight, air, wind, etc., they are continuously available and their quantity is not affected by human consumption. The way we are using our non-renewable resources is proven that it is effecting our economy in a bad way, maybe the cause of global climate change. Natural resources such as coal, petroleum, oil and natural gas take thousands of years to form naturally and cannot be replaced as fast as they are being used. Eventually natural resources will become too costly to harvest and we will need to find other sources of energy. The main energy sources used by humans are non-renewable because they are cheap to produce.
