The retention capacity of global resources is gradually being pushed to its limits and will continue with a population expected to increase by 70% by 2050. While As the world's population continues to increase, so does the consumption of large amounts of natural resources, including the depletion of non-renewable products such as fossil fuels. A combination of alternative energy sources and a reduction in dependence on fossil fuels can reduce the effects of global warming. To combat this problem, scientists have turned to biofuels. Biofuels are energy sources produced from living organisms that can reduce greenhouse gas emissions into the atmosphere. Proponents of biofuels argue that they can reduce greenhouse gases by growing plants or biomass that remove carbon dioxide emitted by crude oils from the atmosphere. However, critics say biofuels pose a threat of global food shortages and unpredictable environmental changes. The necessary measures must be put in place to counteract the damage caused by oil to the environment and the coming energy crisis surrounding it. Biofuels require urgent global priority due to the upcoming energy challenges in the coming years and cellulosic biomass has the potential to meet future energy needs through higher production yields. Growing demand for energy is expected to increase by at least fifty percent by 2050, while crude oil resources are rapidly declining. without possibility of replacement. Abandoning the world's dependence on fossil fuels is another step forward in managing greenhouse gas emissions. The U.S. Department of Energy has set a goal of replacing thirty percent of its liquid petroleum with biofuels in an effort to encourage a movement...... middle of paper ... sustainable energy. The environmental impacts are more appealing to those that oil refining releases into the atmosphere. Biofuels are exceptional for replacing oil since the biomass that creates the biofuel removes carbon dioxide from the atmosphere. Biomass can also be planted in poor agricultural conditions, making the production and conversion process billions of dollars cheaper while increasing income yield. Without being in direct competition with cultivated land, biofuels could not influence food demand. Unlike biofuels, oil lacks the sustainability and ability to end dependence on foreign oil, thereby creating higher economic income. The benefits of biomass converted to cellulosic ethanol are endless. Failure to invest in this new technology will have detrimental effects on the global environment while plunging the world into an energy crisis..
