Crop Biodiversity is a very important to the world we know. As populations grow around the world people are going to consume more food. This can cause a problem without crop biodiversity. Crop biodiversity is the outcome of the interactions among genetic resources, the environment and the management systems and practices used by farmers. This is the result of both natural selection and human interventions and human inventive developed over millennia. Crop diversity helps when trying feeding growing populations with smaller amount of cropland. Crop biodiversity is used in several different ways like pest control, pollination, pollution and sediment regulation, maintenance of the hydrological cycle, erosion control, and climate regulation and carbon sequestration.
Crop diversity in pest control has made a big impact on growing crops in areas that are dominated by pests that would eat up a crop as soon as it flowers. Crop biodiversity has made crops able to withstand roundup and different types of pesticides, which keep pests off the crops while they are growing. Thus letting crops grow to their full potential in area of the country that before crop diversity wouldn’t have been able to happen. This helps in utilizing land for growing crops to feed growing populations when good land is being utilized for building structures.
Crop biodiversity is also used to keep food safety obtainable in the growing world of food safety programs like the FDA. The FDA ensures every crop being
Agronomists have been working on these problems for years, but the rapid population growth of humans makes overcoming these challenges increasingly urgent. If we can’t feed the world, it will eventually feed on us.” (Newsweek/United Nations) Scientists find a way to add “medicine” to plant genes, which help it withstands pest attacks and drought problems.“Some GMO corn crops can protect harvests in water-limited conditions better than conventionally produced crops. Other GMOs can also promote use of no-till farming, which keeps more moisture in the soil. No-till also enables farmers to make fewer passes through the field using machinery, which means less fuel used and greenhouse gases emitted.”(Monsanto) GMOs are useful for helping with planting crops in any area of the world.
Most times this view refers to insects or plants being harmed by the crops. herbicide, fungicide, and pesticides. All of these could be used in reduced amounts with the use of more GMOs. This would keep herbicide, fungicide, and pesticides out of our rivers, creeks, and streams. Which helps the environment.
Secondly, increased shelf life of genetically modified foods will enable it to be shipped to distant locations and cut costs as well as minimize waste to consumers. These foods are modified to be pesticide and herbicide tolerant, resulting in less use of chemical sprays; reducing soil contamination and pollution. In addition, genetically modified crops are more resilient, weather tolerant and capable of surviving in adverse climates such as droughts and extremely cold weather (Whitman, 2000).
“As biological novelties to the ecosystems, GM crops may potentially affect the fitness of other species, population dynamics, ecological roles, and interactions, promoting local extinctions, population explosions, and changes in community structure and function inside and outside agro-ecosystems” (Gertsberg, 2011).
“Biological diversity is of fundamental importance to the functioning of all natural and human-engineered ecosystems, and by extension to the ecosystem services that nature provides free of charge to human society ”(Lloyd, 2014). Biodiversity is very important to both plants, animals and humans on Earth and if one species is destroyed it throw the balance off .
Over the past decades, agriculture technology and productivity has been changing drastically to fit the needs of the world population. The largest agricultural production country, the United States, has been experiencing these changes more rapidly just to meet these agricultural demands. This in turn has lead to serious controversies over the ethics and morals of some agricultural practices, namely Genetically Modified Organisms (GMOs). With the US population increasing every year, US farmers had to develop some way to meet the high demands of the people, therefore, GMOs were developed to help increase crop yields while also helping farmers financially by using less pesticides and herbicides.
The capability to withstand water shortages and the havoc caused by the harvest passes makes the plants to mature early with its productivity level being high. Regions suffering from food shortages can only undergo starvation for short period before it can start to enjoy the food. On the other hand, the abovementioned advantages make farmers engage in profitable farming business with the low level of costs of farm inputs and high outputs. This aspect benefits not only the farmers but also the population that stands to enjoy a large variety of food stuff at their disposal.
Biodiversity is the variety of spices within plants and animals in the environment, it is an indicator of ecosystem health.
An issue in today's society is that they genetically modified foods. Is genetically modified give us the same nutrients as the original food or does it take away nutrients. In the Article "Are GM Foods Destroying Biodiversity" by Ian Murnaghan he states "One of the main controversies around GM foods is the potential of these products to affect biodiversity. In the article Murnaghan explains that If you want a farm and crops that you must make sure about that because animals might eat the crops and If you have GM crops the crop with already have pest-control if animals intend to consume.
One of the biggest advantages of agricultural biotechnology lies in its economic efficiency. GM crops are financially beneficial to both the farmer and the consumer. Due to their resistance to pests, viruses, and adverse climates, genetically altered crops produce much larger yields than organic or conventional crops. For example, studies show that if no insecticide is used, a GM crop known as Bt maize has a 48% higher yield than non-modified maize varieties
The issue of producing and consuming genetically altered foods is controversial. Changing the natural content of plants and animals has negative impacts. For instance, genetically altering the DNA of plants or animals have a possibility to create allergens into a food, which results in allergic reactions. Environmentally, genetically modified crops have disadvantages. Plants can be modified to be pesticides and herbicide tolerant. Hence, when plants are sprayed with chemicals, those chemicals contaminate the surroundings. Besides, the chemicals are toxic to some pollinators, this results in the reduction of pollinators, which contributes to the decrease in genetic diversity in crops. The reduction in genetic diversity of plants disrupts the
Most public concern has been focused on human health and safety regarding the use and consumption of these foods, but potential environmental impacts are important to consider as well. Many varieties of genetically engineered crops are intended to decrease the need for chemical pesticides and fertilizers, but the scope of environmental impacts does not stop at chemical usage. Common concerns about GM crops include the effects of cross-pollination, so-called “genetic contamination,” and the escape of GM crops from cultivation and their interactions with native species. Conversely, the environmental benefits of GM crops range from reducing dependence on chemical pesticides to the ability to treat polluted soils with bioremediating plants (Ford, 2004).
In addition, biodiversity will be crucial for humanities continued survival in the case of climate change or widespread crop failures. The majority of people on earth are reliant on four crops for subsistence; wheat, rice, corn, and millet. (11) These crops are threatened by climate change and the spread of disease facilitated by modern transportation. If humanity is to survive such an eventuality it must be ready to draw upon the earth’s biodiversity for replacements. And while there are approximately 50 thousand plant species that could offer alternatives, this bank of resources is quickly thinning as various ecosystems are being destroyed. (11)
Humans have existed since 200,000 years but the Earth has existed around 4.5 billion years. Nature has provided us with everything we have today - food, medicines, materials, chemicals, metals, minerals etc. It can only keep providing us when we maintain the right environment for it to exist. This environment depends on the biodiversity of Earth. The number of species of plants, animals and microorganisms and the various genes in these species, different ecosystems such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Hence Biodiversity impacts everything. We will discuss how Biodiversity plays a crucial role on social, environmental, and economic factors. We will also discuss what
Genetically Modified insect resistant crops produce the toxic substances as a results it effect non-target organism and entire ecosystem. Biodiversity has significant role to balance environment as biodiversity decreases interaction between species decrease and ecosystem and food chain affect adversely. Some weeds are source of food for
