It’s Time to Meet the Future of Meat

Real, Cultured, or Printed? Nowadays we’re accomplishing miracles in the laboratory. It started, of course, with successful cloning, but we’ve moved on to teasing immature stem cells into making all sorts of tissues, such as skin for burn victims, miniature versions of human organs (called organoids) to learn to treat disease, and actual functional organs for lab animals that fulfill the function of a natural organ. More interesting is something that was accomplished back in early 2015. Scientists at Massachusetts General Hospital grew a complete rat forelimb in a petri dish . Fingers/claws, skin, bones, nerves, blood vessels, and muscles all in the right place and functional. In theory, it could be attached to a subject and tested to see if nerve and blood vessels connections were reliable, and if the bones and connective tissue were durable. There is no reason that they shouldn’t be. Meat in a Lab Muscles, of course, are also referred to as meat, and would be fairly undifferentiated from a naturally occurring meat in texture or flavor. What would be the primary difference about meat made in a sterile laboratory? No animals would be slaughtered; there would be no parasites; there would be no fecal contamination; and, most importantly, there would be no antibiotics or growth hormones necessary. There would be no vast tracts of land necessary, dedicated for the use of our current herds of animals. There would be no concurrent crops necessary to feed all these animals as they grew to a size appropriate for the abattoir, and then the local meat market. There would be no need of veterinarian care for herds to treat diseases. It would eliminate animal suffering,because meat would not be sourced from animals at all.  In other words, by just about every popular definition, it would be completely Vegan meat. Of course there are always doubters; those who think meat is bad and artificial meat would be inadequate for some other reason.  It’s very much like people that protest Genetically Modified Organism (GMO) foods—it makes no sense–since everything in our diet is a GMO.  There is virtually nothing in our diet that has not been changed. Franken-Food Everybody loves corn for instance, but 8,700 years ago in Mexico it was known as teosinte, with just a few grains per stalk that would have easily fit on top of a 25¢ coin.  We crossbred many teosinte with more grains than other plants, and eventually came up with the “cob” that was dense with grain.  Yet no [...]

Hydroponics

Hydroponics is - the process of growing plants in sand, gravel, or liquid, with added nutrients but without soil. In agriculture hydroponics has been remarkably crucial in assisting to lower the usage of pesticides and herbicides. This has translated in more fertile soils and has reduced the chemical burden on farms. Genetically engineered crops such as Bt Maize and Bt Cotton are pest-resistant. Better still other genetically modified crops that are drought-resistant have been produced. Such research has been hugely crucial in a world whose need for food has been increasing exponentially. New pesticides and remote sensing have played essential parts in reducing the amount of harmful chemicals that enter the ecosystem, and allowed farmers to meet the ever increasing needs of the planet. However, fungi and insects are developing resistance even to newest pesticides. Potential Benefits of Genetic Engineering In addition, even the best of modern pesticides still enter the food chains and harm humans and animals alike. For instance, in Holland, farmers have had to switch from soil-growing plants to hydroponics because of the accumulation of toxic salts that come from pesticides and fertilizers. The promise of genetic engineering technologies has been in developing pest-resistant crops which do not need pesticides and can grow without the need of irrigation (Eliot, et al 611). Genetic engineers have stated out rightly that there is a lot of hope such diseases can be treated either the insertion of corrected genes or modification of defective genes. Eventually, this hope of totally eliminating genetic ailments and also the treatment of non-genetic diseases is to a large extent attached to breakthroughs in gene therapy (Hammond, 165-166). Another benefit of hydroponics is in the ability to screen for genetic defects in unborn babies. These screenings are essential for parents and medical staff in preparing for the arrival of a child who may have specific needs. A possible potential benefit of genetic engineering that has been awaited with much eagerness is that a fetus that has genetic defects can be treated using genetic therapy before they are born. Revolutionizing Agriculture and Medicine Current there is a lot of research that is going on with regard to the use of gene therapy for embryos before they are implanted into the mother through in-vitro fertilization (Robert, 93-94). Agriculture is one of the fields which have experienced diverse benefits of hydroponics through rDNA technology. This has translated in improved genetic fitness of many plant species. Some of the common benefits in agriculture are increase in [...]

Environmental Changes and our Livestock

Environmental Changes and Livestock: What You Need to Know Livestock sector contributes to a big percentage of agricultural produce its key in the global food security chain. Environmental changes have had a significant impact on livestock farming thus distracting the food supply chain. Climate change is majorly caused by the emissions from greenhouse gas which leads to the warming of the atmosphere. Ironically, the livestock sector contributes to climate change through its contributions to the emission of green gas.[1] This has had serious implications on livestock sector in the US. Some of the effect associated with environmental changes include; Low livestock production: Environmental changes cause an unpredictable weather patterns which has an impact on livestock sector. This has an overall performance on livestock performance which has an effect on the livestock products. Environmental changes also increase vulnerability of livestock as most of the time the environment becomes harsh for the sustainable of the animals.[1] Increase of temperatures during summer reduce animal production while it causes a slow down during winter. Effects on parasites that affect livestock’s: Environmental changes has caused changes and an increase in parasites that affect domestic animals. An increase in diseases such as bovine respiratory disease have been reported to have increased in the last few years. Impacts of Climate Change on Livestock Farming This has been blamed on environmentally factors.  Some of this parasites affect crops which act as foods for the livestock. This has continued to affect plant and livestock diseases in most places in the US. Reduced quality and quantity of produce: The quality of produce such as feeds is degraded as a result of high atmospheric, increase of carbon dioxide and dry conditions. This however is very determined on factors such as location, species, crops, livestock system among others. This affects the quality of forage and feeds.[3] Extreme weather conditions such as floods may cause roots structure and decrease in total quality and quantity. Unpredictable rainfall: Livestock farming relies heavily on agricultural crops, while the growth of this crops needs reliable water. Climate change has affected rainfall pattern which has led to scarcity of water thus affecting the whole cycle. Livestock requires drinking water, crops for product processes. It is estimated that by 2025, 64% may experience constrained water conditions.[4] Reproduction: Livestock reproduction of both sexes is affected by heat stress. This affects cows and pigs in embryo employment development and low pregnancy rates. Cow fertility is compromised by too much heat or deficits. Lower sperm concentration has also been [...]

on Recycling

  Introduction - on Recycling The Recycling Opportunity System has set up a statewide system for managing solid waste that was called the most comprehensive in the nation. Where does the material go next? The destination depends on the particular item in question, but the process of collecting and re-manufacturing recyclable materials is only part of recycling. Therefore, before using a recycled product, look for the recycle label on the products you buy. What exactly is Recycling? Recycling is a process of bringing waste materials into reusable objects to prevent waste of potentially useful materials. After turning a recyclable product into a raw form, they can be used to create a new, different products. Why recycle?  Not only are natural resources limited, but on recycling efforts will reduce additional waste products that may cause harm to human, resources, and nature. Is recycling important? There are various good reasons for adding recycling to our daily life, and this may result from a personal level to a global advantage. Recycling waste products get you more adapted to the way you use and dispose of stuff. It is apparent that people who involve themselves in this insist on buying unwanted things from a supermarket, they think of disposing of those products after use before even buying them. By applying this method, people end up as a result, saving an amount of money while also saving the planet. Some Individuals, governing bodies and other companies also take pride in limiting their waste products as they can help to reduce world environmental damages and make the earth a better place on which to live. It is a direct contribution everyone should emulate. What Can I Recycle? When you think on recycling at times, you think only about recycling materials. However, in reality, almost anything is recyclable. Below some of the common recyclable things are listed. Cars Instead of sending your car to the junkyard or selling it, you can donate it to a charitable organization. Not only will you keep the vehicle out of the landfill, but you will also receive a tax deduction for doing so. Clothes Clothes are one of the easiest materials to recycle as so many charitable organizations will accept them such as Goodwill, Veteran's Support Groups, and most churches. Also, you can sell them at a consignment shop if they are still in good shape and style. Food Start a compost heap in your backyard, then Instead of throwing old food in the trash; throw it on the [...]

PVC ? Environmental Concerns

PVC and Environment: How This Plastic Pollutes the Air, Water and Soil Let’s talk about one of the most commonly used plastics today – Polyvinyl chloride. Or, as we all know it - PVC. In fact, 20 million tons were produced only in 1995. The reason why it is so commonly used,  is because  it’s a low cost material, light weight and comfortable to work with. In this article we will talk about and explain, how PVC is made, what the bad side effects from using it are and what the methods of its disposal are. How PVC  is made? In very simple terms – by linking monomers (a molecule that can be bonded to other identical molecule) together. This creates polymer that can occur in two shapes: rigid and elastic. We get a flexible polymer when we add Plasticizers in the rigid one. Plasticizers are an additive, which passes on special rubber-like attributes of the polymer. (For a more elaborated version of how PVC is made, visit Manufacturing polyvinyl chloride (PVC) is a three-step process. In the process of making PVC, other additives are used as well, such as: impact modifiers, fillers, processing aids, smoke suppressors, UV stabilizers and optionally, pigments.  What the end product would be used for will decide what sort of additives will be added in the process. Many of these additives are released into the nature when PVC’s are getting made. This delivers a bad effect on the environment, which we will talk about in the succeeding chapter. Why  PVC is bad for the Environment? With the use of raw chemicals, the production of PVC can be harmful for the surroundings. Particularly for the environment that is close to where it is being made. For example, residents from Mosswile, Louisiana – a town that is close to a chemical facility for production of PVC – have  had three times more than normal dioxides level in their blood. All this is caused from the pollution of the water, ground and air. The pollution, of course, comes from releasing and disposal of additives during the devising process. In putting out these chemicals, which some are classified as carcinogenic, we risk our health. In fact, dioxin – one of the elements that occurs in the process, has been classified as a known human carcinogen. This is confirmed by the International Agency for Research on Cancer and U.S. National Toxicology Program. Latest research indicates that there is no safe level of dioxin exposure for humans. Tests [...]

Plastic, how it made and its Impact

Plastic and its impact: How it is developed and how it damages the environment Starting from coffee cups and shopping bags all up to protective gear and food packaging – plastic is a big part of our lives. Plastic is around us more than many realize, and it’s an important part of our everyday living. But, should it be? How safe it is? In this article, we will try to cover many how it is made and what exactly is plastic. Hopefully, we will bust some myths about it and give you a new insight for it. It’s Organic That’s correct – it is made from oil and/or plants. The first one that is made is from oil actually made from naphtha – a type of oil that cannot be refined for gasoline or motor oil. The second one that is made is from plants is a bioplastic – mostly used for disposable items like packaging, straws, pots, etc. The method of making it is a long one, but we will try to explained in short words: - The Naphtha is processed into polymers , substances that are formed by chemical reaction in which large number of molecules (monomers) are joined together – creating a chain. - Different combination of monomers can yield the plastic resins with different properties and characteristics. - When the plastic finally emerges from the reactors, it’s not yes as we wanted to be. So therefore, additives are added (hence the name :). Not only that additives are meant to change the mechanical, physical and chemical properties of the plastic, but to protect it as well, from light, heat or bacteria. Bioplastics are made from plants such as corn, orange peels, cellulose, etc.  A good thing about this kind of plastic is that it is  compostable: these plastics can decay into natural materials. There are 2 types of polymers (plastic) -Thermoset, plastic that once is made – it cannot be changed. -Thermoplastic, plastic that once exposed to heat it returns in its original condition. Environmental effects that plastic can cause With so many plastic products around us, some kind of impact on the environment is expected. Some of those impacts include: -Danger to animal life There is a big amount of plastic bags and bottle in our oceans. In fact, that kind of trash in the Pacific is estimated that is a size of Texas. This not only cause dangers to the marine life, but to us as well. Many countries spend a lot [...]
