Veganism As A Way To Save The Planet

Recent trends show that an increasing number of people are moving towards plant-based diets. There are even more vegan or vegetarian options in restaurants and supermarkets. Researchers claim that veganism is a healthier option and has limited impacts on the environment. In this article we shall explore these claims.

What is Veganism?

Veganism is a lifestyle that subscribes to refraining from consuming animal products or purchasing any products that were derived from animals. A vegan or plant-based diet excludes all animal products including eggs, dairy, and meat; some also choose to avoid honey.

People tend to interchange veganism and vegetarianism. The two terms are similar; however, vegetarians do not eat meat but consume dairy products, eggs, or both.

When done in the right manner a vegan diet can be highly nutritious especially since they tend to be rich in nutrients and low in saturated fats. Vegan diets mainly consist of fruits, vegetables, beans, nuts, and seeds thus eliminating any sources of harmful animal fats. However, people on a plant based diet need to be aware of how to obtain certain nutrients such as iron, calcium and vitamin B-12 that are readily available in an omnivorous diet. Vitamin B12 helps prevent nerve damage and is found mainly in meat, fish, eggs and dairy but not in fruit or vegetables.

The veganism lifestyle has become very popular in the recent past and many have adopted it due to health, environmental concerns, and animal welfare. Some advocate for a vegan diet due to its limited environmental impacts and adopt it as a sustainable diet, which has low environmental impacts, is healthy and contributes to food security for future generations.

Health Benefits

Research shows that vegan diets have health benefits such as reduced risk of heart disease, obesity, diabetes, cancer, and premature death. In addition to this, plant food contains no cholesterol unlike meat, eggs and dairy products which contain large amounts of cholesterol and saturated fats which is a major trigger for many health issues. Contrastingly, the high fiber content in a vegan diet helps wash away any cholesterol in the digestive tract.

Animal products contain harmful contaminants including bacteria, arsenic, dioxins, and mercury that can affect our health. Fish tissue has also been found to harbor levels of polychlorinated biphenyls (PCBs) thousands of times higher than in the water in which they live often because of biomagnification.

The overuse of antibiotics on factory farms has caused many of the bacteria found on animal flesh to become antibiotic resistant. Many opt for veganism to avoid side effects linked to antibiotics and hormones used in animal agriculture.

Animal Cruelty

Ethical vegans believe that all creatures have the right to life and freedom and are against ending a life simply to consume its flesh, or wear its skin. They are opposed to the physical or psychological stress animals endure during modern farming practices. Furthermore, vegans deplore the crammed pens, filthy battery cages and restrictive enclosures that animals live in and the fact that the animals hardly ever leave between birth and slaughter.

To this regard, ethical vegans demonstrate their opposition by protesting, raising awareness, and choosing products that don’t involve animal agriculture.

In terms of the treatment of animals, farm animals experience a lot of cruelty. They are mutilated mercilessly, their necks and throats hacked and slit open or are submerged in scalding hot water when still conscious. Moreover, calves are killed for veal and cows are put in a continuous loop of pregnancy, birthing and milking.

The main objective of factory farms is to maximize output while minimizing costs always at the animals’ expense. This leads to animals being squeezed into tiny spaces and being exposed to diseases and infections.

Environmental Concerns

People may choose to avoid animal products because of the environmental impact of animal agriculture. According to a report by the Food and Agriculture Organization (FAO), livestock account for 14.5 percent of all greenhouse gas (GHG) emissions globally. This accounts for approximately 7.1 gigatonnes of CO2-eq every year with beef and cattle milk production accounting for 41 and 20 percent of these emissions respectively. Pig and poultry farming account for 9 and 8 percent respectively. The three main GHGs emitted by this sector are nitrous oxide, methane, and carbon dioxide.

Secondly, deforestation is a growing concern in the spread of animal agriculture. Forests are cut down or burned to create space for livestock and their feeds as seen in the Amazon forest. Consequently, numerous animal habitats are being threatened due to this.

Lastly, large amounts of water are used for the consumption of livestock and the watering of the feeds. For example, in milk production, it is estimated that a cow would need 150 litres of water per day. Therefore, animal agriculture has a large footprint in terms of greenhouse gas emissions, water, and land use.

It should also be noted that the global production of avocados, a vegan favourite, required a water estimate of 2.82 million Olympic size swimming pools (each containing 2.5 million litres of water) in 2018. Although these statistics account for worldwide avocado consumption, veganism may not be without its own faults.

Conclusion

It is evident that the consumption of meat, eggs and dairy contribute to environmental degradation. Currently, people consume way too much meat and dairy. My take on this is one does not need to follow a strict plant-based diet to reduce their footprint. However, I would advice that we reduce our meat intake significantly. Perhaps do Meatless Mondays, scale down on the number of times you eat meat a week or substitute meat and dairy products with vegan alternatives. I strongly believe that if we all reduced our meat intake it could have a positive impact on the environment.

What’s your take on veganism? Would you become one on the account of the environment?

The Truth About Food Waste

Presently, we have become such a wasteful generation. When it comes to water, fashion and even food. The worst part about wasting food is that more than 820 million people have no access to sufficient food. Let us take a look at the extent of food waste in the world.

Food waste is the amount of food that is discarded or thrown out at consumer or retail level. Basically, when people throw out food they don’t want to eat or leave it to spoil.

On the other hand, food loss is the amount of food lost during the harvesting and pre-processing stages. In Africa, food is lost due to lack of proper infrastructure in the harvesting, processing, and storage stages, due to financial, managerial, or technical constraints.

About one third of food produced globally is lost or wasted every year. This equates to roughly 1.4B tones of food. In high income countries the estimated worth of their food waste is USD 680B and 310B in developing countries. In medium and high-income countries, food is wasted in later stages in contrast to developing countries where there is reduced wastage due to low purchasing power and supply.

In developed countries, more than 40% of food waste occurs at retail and consumer levels and is heavily determined by consumer behaviour. Great quantities are lost due to the cosmetic appearance of food. Contrastingly, 40% of food losses in developing countries occur at post-harvest and processing levels as mentioned above. The most wasted food type in the world is fruits and vegetables. According to the UN, about half of all fruits and vegetables produced are wasted.

Effects of food waste

Food loss and waste result in the misuse of resources. These include water, seeds, feeds, land, energy, and labour. It is estimated that half the water used to produce this food is wasted. It also leads to the emission of greenhouse gases that contribute to global warming and climate change. According to FAO, 8% of greenhouse gas emissions is from food waste. Discarded food is taken to landfills where it rots and produces methane gas that is a major greenhouse gas.

What countries can do

Ironically, 690 million people around the world are undernourished while so much of the global food supply is lost. It is projected that food waste will continue to rise in coming years if nothing is done about it. The limited transparency about the extent of food loss and waste in the food chain coupled with the lack of awareness among food providers and consumers is further exacerbating the issue. Coordination between producers and processors would greatly reduce food loss and waste.

Finding a beneficial use for food that is thrown away is a useful measure to decrease the amount of loss and waste – recycling food. In addition, manufacturing industries could repurpose and recycle unmarketable crops, by products or waste into other products such as biofuels or animal feeds.

Cold chain is a great technology that can reduce food waste. It involves a series of refrigerated production, transport and distribution activities. This could work to prolong and extend the shelf life of food. However, it is not easily available in emerging economies.

Farmers should be trained on how to protect crops from pests, diseases and weeds. This could reduce loss during harvest.

Retailers should sell imperfect fruits and vegetables at discounted prices.

What you can do

  • Buy what you need: avoid impulse buying or steering off your grocery list
  • Use old products before opening new ones.
  • Buy imperfect fruits – oddly shaped or bruised produce are often thrown away because they do not meet cosmetic standards. Old fruits and vegetables can be used in desserts, smoothies and juices.
  • Store food well: put older products at the front of the fridge or store and newer ones at the back to prevent food spoilage. Garlic, potatoes, tomatoes, cucumbers and onions should never be placed in the fridge but at room temperature. Foods that produce ethylene gas should be separated from the others that do not. Ethylene gas promotes ripening in foods. Examples of foods that produce it are tomatoes, bananas, avocados, pears, and green onions.
  • Understand food labeling. Understanding the difference between ‘best before’, ‘use by’ and ‘sell by’ can help prevent a lot of food waste. In some cases food may still be safe to eat past the ‘best before’ date but the ‘use by’ date indicates that it is not safe to eat. ‘Sell by’ is supposed to inform retailers when the product should be sold or removed from shelves.
  • Avoid throwing away food. Take leftovers and turn it into compost. This will create nutrient rich manure for your garden and prevent organic waste from ending up in landfills.
  • Support local farmers, markets, and small businesses in your community. This can help fight pollution from long distance deliveries.
  • Eat the skin of fruits, vegetables and chicken. There are a lot of nutrients in the outer layer of potatoes, chicken skin, carrots, mangoes, and cucumber therefore avoid binning them.
  • Practice portion control when preparing dishes and serving. Only serve the amount of food that you can finish to avoid wasted food on the plate.
  • Donate food to local charities and people in need.

For many, food waste has become a major problem by buying more than we need and letting food go to waste. The importance of reducing food loss and waste is that it can increase incomes and improve access to food for vulnerable and disadvantaged groups in high-risk regions. By eliminating the food loss and waste problem, we can also curb its growing carbon footprint.

ARE GMOs THE ANSWER?

GMOs are a widely controversial topic and many have split views about their use. In this article I would like to shed some light on its applications in agriculture, medicine and livestock as well as its effects on the environment.

What are GMOs?

A genetically modified organism (GMO) is an animal, plant or microbe that has had its DNA altered or modified in a lab through recombinant DNA technology and reproductive cloning (genetic engineering). This creates a combination of genes that do not occur naturally.

Initially, artificial selection was employed by using traditional breeding techniques to get a desired trait in animals and plants. This involved the selection of the animals and plants that would get to reproduce. This has been done with maize crop, cattle, dogs etc. However, the method is limited to natural selection which is random. On the other hand, genetic engineering has enabled precise control of the genes introduced into an organism which ensures that the desired traits are expressed.

Agriculture

GMOs are popular in the farming industry because they are tailored to produce higher yield crops that are resistant to pests, diseases, adverse weather conditions such as drought as well as some pesticides/herbicides.

Genetically engineered foods have foreign genes from other organisms inserted into their genetic codes; that translates to elements in crops that enable them to be drought and pest resistant.


GM Foods (olmag.co/gmo-foods)

The main GM crops are cotton, soybean, maize and canola.

It is worth noting, crop derivatives such as yeast, sucrose and vitamins from GM plants also contain genetic engineered material.

GMOs may appear as a solution to food insecurity however little is known about their long-term effects. Anti-GMO activists argue that GMOs can cause human health problems by triggering allergic reactions or contributing to cancer development possibly brought about through mutations in DNA. However, there is no concrete scientific evidence to support this at present.

In addition, there are claims that GM crops that are designed to be resistant to herbicides and certain antibiotics could pass this resistance to humans. This would make people resistant to antibiotic treatment thus reducing the efficacy of the medication. However, these claims call for further research.

Medicine

GMOs have extended to the biomedical sector where research is underway to produce edible vaccines. These will be plants (fruits and vegetables) that have vaccines incorporated into their genetic code for direct consumption by people. This could potentially curb the spread of diseases and provide a solution for developing countries that are not able to afford the equipment for vaccines or conduct large scale vaccination campaigns.

In addition to this there are further medical trials to use GM animals to grow human transplant tissues and organs in a procedure known as xenotransplantation.

Livestock

GM crops are beneficial to the livestock sector. Plants used as animal feeds are engineered to produce high yields with better quality traits. Farmers are able to produce more ingredients for the animal feeds on the same tract of land. Meaning there will be reduced land use and no need to expand agricultural land into natural spaces.

Consequently, the genetically modified animal feeds may transfer the genetic material to the animal. Therefore, it is likely that animal products such as milk, eggs and meat could have genetically engineered elements present.

 

Environmental implications

Advantages


  • A major draw for GMOs is pest resistance. The bacterium, Bacillus thuringiensis (Bt) is used for its protein properties that repel insects. GMO crops that have the Bt gene incorporated in their DNA are able to repel insect pests, thus minimizing the use of pesticides.
  • GM crops tend to produce better harvests than conventional crops therefore less land is required to grow more food.

Disadvantages


  • Inbreeding may occur between GMOs and natural organisms which may lead to biodiversity loss.
  • The reliance on GMO seeds may grow to the point where indigenous crops will be slowly phased out of the agro-ecosystem.
  • Certain GM crops are modified to resist chemical herbicides instead of pests (weeds). Herbicide resistant crops are able to survive the chemical effects of specific herbicides that are used to control weed populations. Although this reduces tilling which leads to soil erosion, it encourages the increased application of herbicides in farms which perpetuates soil pollution.

Conclusion

GMOs offer many solutions in the world today; however, since it is a relatively new technology we cannot be sure if it’s the best or safest practice to embrace.

In the comment section below let us know if you are for or against GMOs. We would love to hear your views!

Climate Change Food

Climate Change and Food Security

Food security is the state when everyone at all times has the economic and physical access to nutritious, safe and sufficient food to meet their dietary needs and food preferences for an active and healthy life according to FAO.

Food sources can be categorized as agriculture, livestock and fish farming. They all rely heavily on the state of the surrounding environment.

Agriculture

Agriculture is heavily dependent on the weather; it requires the right combination of rain, sun and warmth to produce the food that we all need.

Farmers in sub-Saharan Africa are especially vulnerable to climate change because they rely on rain fed agriculture as opposed to irrigation systems.

Farming is also seasonal as farmers have to harvest before the end of each season in order to prepare for the next.

According to the United Nations, 80% of the world’s food production is by family farms. Therefore, climate change will not only affect these families at an individual level, but the world as a whole.

Factors that affect agriculture:

 

  • Extreme weather: erratic weather is a hallmark of climate change which can manifest in various ways, i.e., droughts, storms, floods, frosts and heat waves. It is expected that there will be an increase in the intensity and frequency of extreme weather events in the future as the Earth’s atmosphere continues to warm.

 

  • Pests and diseases: when there is a change in temperature and moisture levels, crop diseases and pests can thrive. One example of a pest is the fall army worm that has invaded farmlands in certain African countries. This is an invasive caterpillar that is known to devastate maize yields.

 

  • High temperature: average global temperatures should rise in coming decades which would lead to severe desertification and painfully small yields.

Unfortunately, many farmers in developing countries turn to unsustainable avenues to increase their yield such as deforestation, converting natural land to farmland and other unsustainable agricultural practices which lead to a vicious cycle of land degradation and low yields.

Agriculture is a necessity for all humanity because it provides a source of food as well as a primary source of livelihood for around 36% of the world’s total workforce according to FAO. The impacts of climate change are expected to be negative in tropical regions and positive in temperate zones. We may see higher yields in temperate regions which could potentially offset lower yields in tropical zones. However, low income countries with limited financial capacity to trade and high dependence on their own local production of food may find it difficult to offset declines in food supply without a reliance on food aid.

Livestock farming

Heat waves have been known to increase with climate change and this may pose a risk to livestock. The heat can affect livestock directly or indirectly by making them more vulnerable to disease, reduced fertility and reduced milk production. It can also increase the prevalence of parasites and diseases that affect livestock which will lead to the increased use of pesticides that will be introduced to the food chain.

Climate change is a threat to livestock production because it impacts quality of feed crop and forage, animal and milk production, water availability, livestock disease and animal production. Due to an increase in temperature and carbon dioxide the quantity and quality of feed will be affected.

Ironically, the livestock sector is also perilous to the environment by emitting 14.5% of global greenhouse gases and contributing to land use change.

Fisheries

Fisheries are already under stress with overfishing and water pollution. With aquatic waters warming, many aquatic species have been forced to search for colder areas of streams and lakes or move to higher latitudes where temperatures could be more conducive for their survival. This potentially could put them in competition with other species for food and other resources. Trout and salmon are examples of fish losing their habitat due to the migration of warm water fish into cold water regions.

There will be changes in catch size of sea food as fish species change their geographic distribution and migration patterns due to climate change. This can impact national incomes of countries that solely rely on fisheries.

Conclusion

Climate smart agriculture (CSA) is a solution to aid farmers in the wake of the climate crisis. By implementing climate change adaptation and mitigation measures such as ecological farming, agroforestry, crop rotation and more; sustainable agriculture could be achieved which will go a long way with improving food security in several countries.

Additional information on CSA

There are three pillars of CSA, namely, productivity, adaptation and mitigation. CSA aims to increase agricultural productivity and incomes sustainably, reduce farmers exposure to short-term risks, and reduce greenhouse gas emissions. A successful case of CSA intervention is the development of drought-tolerant maize for Africa (DTMA). This has seen the development and successful farming of drought-resistant maize varieties in Sub-Saharan Africa.

In livestock farming, CSA, is achieved through better feeding using crop by-products, agroforestry, fodder banks and improved pastures species. A successful case of CSA intervention in livestock farming, is the East Africa Dairy Development Project (EADD). The project supports about 200,000 farmers by increasing their milk production in Kenya, Uganda and Rwanda.

In fisheries, catfish aquaculture is seen as the alternative source of protein for mankind. Catfish aquaculture consumer less water per tonne, has few impacts on water quality, and allows the use of both wastewater and discarded fish parts as fertilizer and animal feed/oil respectively. Catfish aquaculture has proven to be a successful CSA intervention in countries like Vietnam generating 1 million tonnes of food every year and employing over 170,000 people.
