Earth is a sustainable planet which produces life, sustenance, and shelter to billions of its residents, but the climate of the planet is changing and we must also change with that. To continue to get in the advantages of this planet's nourishment we have to discover ways and solutions to grow food that is able to brave the storm of climate change. Different solutions have presented it selves, but one stand out opposite the others as a possible fix to food that affected by climate change problem. That solution would be foods or crops which are genetically modified.

GM crops or foods are plants created by the latest technology in agricultural science and microbiology. Much in the similar way that certain pets breed to continue specific characteristics, GM crops and foods create to increase certain traits that formulate them modified to specific areas, constructs, and situations. For instance, different benefits of GM foods are that these can make to disease resistant, pest resistant, extra nutritious, herbicide tolerant, and most definitely can stand up to consequences created by climate change. This is relevant to the global warming debate because by producing crops that can defend Mother Nature from Mother Nature we can use, produce, and consume food that can outlast any change in climate.

There has been a fast growth in genetically engineered foods and crops in the US. It can connect to companies and organizations investing in GM crops as the prospect of food consumption and production. For instance, US biotech companies such as Monsanto have started testing drought tolerant and water efficient engineered crops which can continue to produce and survive in case of flood or drought cause from climate change.
Through the application of no-and low-till farming methods, CO2 emissions and fuel use can reduce thanks to less tillage. This led to reductions of global emissions of 17.7 billion kg CO2, comparable to 7.7 million cars on road for one year.

GM crops can assist farmers combat climate change in following ways:

• Less fuel use on farms because of a reduced requirement to spray crops.
• Better C sequestration: With less plowing or tillage, over the time soil quality improve and becomes C-enriched since more crop remainder can left on the lands. Additionally, since the soil is not tilling, less carbon in soil will emit into the atmosphere.
• Less fertilizer apply and Nitrous oxide emissions: N2O has a global warming possibility 300 times greater than C2O. And it resides in the atmosphere for 100 years or more. These emissions can restrict by reduced fertilizer use that will also show less water pollution.

Every year, between 20,000 -50,000 km2 of cultivable land is projected to be lost worldwide through degradation, particularly erosion of soil. GM crops are able to protect soils from erosion by less plowing, preserving soil moisture. GM herbicide tolerant crops lessen the need to plow lands in preparation for planting various crops. This saves fuel cost because less tilling is needed. Insect resistant GM crops need less treatment with pesticides, which also reduces the need for use of tractor.

Water use has tripled during the last five decades globally. On average, it requires about 2,900 liters of water for every person to produce our daily ingestion of food. GM technology can aid to lessen water loss from agricultural use and to develop drought tolerance. Several GM crops cut the need for plowing. This indicates the soil is not cultivated as much that helps to hold soil moisture. Under drought circumstances, this can mean the variation between containing a crop to yield and crop failure.

Although these were not basically developed to improve our environment, a lot of GM crops help to conserve water, prevent erosion, reduce carbon emissions, and produce more crops on less land area. All GM crops which are presently on the market have established to safe for the environment and health.
Presently, insect-resistant and herbicide-tolerant plants make up more than 90% of the GM crops; both contribute to decline in farmer's usage of plant protection products.

Sure, GM foods do have its detractors who dispute that the chemically modified food hurts biodiversity and isn't safe, however the positives outweighing the negatives. GM foods are an obvious solution to the outcomes of climate change and can aid support food production stable in an unsteady climate.
