Humankind has always adapted its environment to its needs. But now, biotechnology is accelerating our ability to bend nature seemingly to our will.
Modern biotechnology covers various crucial industries, from human healthcare to genetic engineering of plants. This science fiction-type adaptation of living organisms could hold the key to many pressing issues in medicine, agriculture, energy, and more.
And while the U.S. leads the world in biotech, with China also investing huge sums, countries like Denmark, Switzerland, and Spain are also making their mark.
Biotech offers enormous financial rewards for those who find innovative ways to improve our lives. Here’s how biotechnology has kickstarted a new tech race, with the final destination unknown.
What Is Biotechnology?
Biotechnology takes existing living organisms in their original or modified form to create new technologies and solutions to problems. That biological process could be as simple as using yeast to bake bread or fermentation in brewing.
Modern science, gene therapy, and genetic engineering have pushed back the boundaries of that early, bread-making biotech. With biotechnology, we can radically alter our environment, plants, animals, and even our bodies.
What Are the Most Important Biotech Industries?
The main applications of biotechnology are the following:
- Genetic engineering modifies the genomes (DNA) of plants, animals, and microbes to create favorable traits such as disease resistance or different crop flavors. Stem cell research involves studying life’s building blocks to find potential new medical treatments.
- Biochemistry explores the chemical processes of living organisms. This can help with industrial processes like refining and identifying plastic-eating enzymes like PETase and MHETase.
- Molecular biology studies the structure and functions of molecules and microorganisms, such as proteins, essential to life.
These biotech techniques, including agricultural biotechnology, can be used practically to reduce farming’s environmental impact, produce biofuels, improve food products, and extract renewable gasses from biomass.
Other biotechnology products include chemicals, food, medicines, and vaccines.
An Unrivaled Breakthrough: Understanding the Human Genome
The International Human Genome Sequencing Consortium announced the successful (92%) completion of the Human Genome Project in April 2003. The entire human genomic sequence was completed in 2022, giving scientists a full insight into human DNA.
Such information has been crucial to biotech. Scientists strive daily to find remedies for previously untreatable diseases using biotechnology.
Gene therapy allows us to change or manipulate someone’s genes to cure diseases and pathogens. A pathogen is any organism, a fungi, bacteria, or virus, that causes disease.
For example, the human genome is used in healthcare products and vaccines, including COVID-19 vaccines like Pfizer. Artificial Intelligence (AI) is accelerating this process, using genomic information to unravel the mysteries of life.
Thanks to biotech, Jennifer Doudna and Emmanuelle Charpentier won the 2020 Nobel Prize in Chemistry. A system called CRISPR helped them use the body’s antibodies to recognize, remember, and attack invading viruses and diseases. Much the same happens when we catch a cold. However, CRISPR could help fix mutated genes or regulate a defective one via cell therapy, opening up the possibility of treating a wide range of diseases.
In 2019, Victoria Gray’s life changed completely thanks to CRISPR biotechnology. Victoria became the first person to have gene-editing treatment for her sickle cell disease, taking her from being continually fatigued and frequently in the hospital to getting a full-time job and enjoying travel.
Spain: A Rising Biotechnology Power
While the United States—mainly California, Boston area, New York, and New Jersey—dominates biotech’s estimated $436 billion global trade, Spain is fast emerging as a biotechnology center.
Its principal research arm is medical biotech. Its excellent public hospitals and vast patient databases make it perfect for clinical trials. One in three medical biotech trials in Europe happens in Spain, second only to the U.S., with between 4,000-5,000 current projects.
Spain led Europe’s COVID-19 vaccine trials. Catalonia is Spain’s diagnostics capital, nicknamed the BioRegion. Here, more than 1,300 biotech firms and 91 research institutions innovate in the use of biotechnology. Elsewhere, U.S. vaccine manufacturer Moderna chose Madrid to invest $500 million to test its mRNA vaccines.
The biennial BioSpain, next held in September 2025, is the largest biotech event in Europe and attracts global industry leaders. Overall, biotech is worth almost €20 billion to the Spanish economy, some 1.5% of GDP, supporting nearly 170,000 jobs.
How Is Biotechnology Used in Medicine?
Biotech explores the toolbox nature has already provided. Microbial biotechnology—using naturally occurring microorganisms as technology—is crucial to developing new medicines.
This use of biotechnology will hopefully help reduce infectious diseases, save lives, and improve the quality of life for millions of people with severe or life-threatening diseases. Disease detection may improve, countering emerging threats such as COVID-19. Biotech drugs, called biopharmaceuticals, already account for almost 40% of worldwide drug sales.
Spain’s role in medical biotechnology is impressive. Current projects include:
- Developing blood tests for early cancer detection and drugs to attack advanced cancers.
- Potential therapeutic vaccines for HIV.
- Medicines to help people with neurological diseases such as Borderline Personality Disorder.
- A gene therapy for a rare genetic eye condition called Stargardt disease.
- DNA-based drugs for rare genetic diseases that affect the eyes, lungs, or kidneys.
Oncology is prominent in biotech research. The Keytruda treatment works alongside a cancer sufferer’s immune system. It is now the world’s top-selling biopharmaceutical, with an annual market value of $25 billion. Humira (adalimumab) is now often prescribed for rheumatoid arthritis and psoriasis.
What Are the Applications of Biotechnology in Agriculture?
Agricultural biotechnology is revolutionizing how the world feeds its rising 8.2 billion population.
Genetically engineered (GE) seed varieties have been used in America—the world’s largest food exporter—since 1996. Nowadays, the successful commercialization of biotechnology-derived crops means more than 90% of U.S. cotton, soybeans, and sugar beets are GE crops regulated by the U.S. Food and Drug Administration (FDA).
GE crops have edited genomes (DNA) via molecular biology to bring one or more of the following benefits:
- Increased resistance to pests, disease, fungi, viruses, and drought results in less pesticide use that can pollute groundwater and the surrounding environment.
- Enhanced herbicide tolerance.
- Delivering higher crop yields with plants that contain higher vitamin and nutrient concentrations yet require less water and nutrients.
- Removing some allergens and toxins from crops.
- Making food production cheaper through more vigorous plants that require fewer pesticides, resulting in simpler farming and lower costs.
- Improving soil quality.
- Reducing dependence on fuel, labor, water, and fertilizers to improve farming sustainability.
For example, in Hawaii, biotech researchers developed the Rainbow Papaya to resist the previously devastating papaya ringspot virus, saving the industry. Spanish winemakers have used biotech to improve vineyard management, pair the perfect local yeast to ferment with grape varieties, and help reduce winemaking’s environmental impact.
What Are the Applications of Biotechnology in Energy?
After medicine and agriculture, the energy industry is a massive beneficiary of the use of biotechnology. This is particularly true for exploring previously untapped renewable energy sources in biomass (organic materials).
Bioenergy covers everything from crops used to make biofuels to methane gathered from landfill sites. Biotechnology means crops like beets and corn, whose sugars are biochemical substances used for biofuels, can be genetically altered to increase their biofuel production capacities.
Scientists can also examine many biological processes, like fermentation, to discover new ways to improve energy gathering and dispersal. Benefits include streamlining manufacturing processes, reducing chemical dependence, and analyzing enzymes in products like detergent to improve cleansing efficiency at lower wash temperatures.
These energy-saving uses of biotechnology can help reduce greenhouse gas emissions that cause climate change, reduce water usage, and make the most of biomass waste products.
How Is Biotechnology Used in Environmental Conservation?
Biotechnology helps environmental conservation through the following:
- Reducing waste and conserving natural resources.
- Controlling pollution thanks to pest and disease-resistant crops.
- Maximizing renewable energy sources.
- Protecting biodiversity.
Examples include genetically engineered fruits and vegetables that stay fresher for longer periods. This reduces food waste.
Farm animals may be fed more nutrient-dense feeds thanks to biotech. Improved industrial processes conserve natural resources, and hardier crops require fewer pesticides, decreasing polluting runoff into waterways and soils.
There’s more. Microorganisms help clean oil spills by feeding on and breaking down the oil into less harmful substances. Microbial fuel cells (MFCs) use microbes that simultaneously break down organic matter and produce electricity.
What Is Biosafety and Why Do We Need It?
Biosafety, or biosecurity, means preventing biological risks to plant, animal, and human health. Biosafety is achieved through analyzing and managing those risks through rules and establishing barriers.
Ultimately, biosafety attempts to prevent or minimize biological contamination or exposure to harmful biological agents. Biosecurity also protects us from the deliberate release of toxins or pathogens, such as anthrax attacks or nerve agents. Crops susceptible to pathogens or toxins also require biosafety measures.
Biotechnology advances are not all win-win situations. Laboratories, farmers, and government agencies must all be aware of the importance of biosafety to keep its citizens and borders safe from potential attacks. The more advances biotech makes, the more vulnerabilities may emerge.
What Are the Ethical Issues in Biotechnology?
Many people are skeptical about biotechnology, both its uses and very existence.
Commercialization upsides like greater crop yields and disease resistance may benefit a company’s bottom line profits, but others point out that profit-driven does not always mean health-driven.
Farms risk becoming homogenized, with few crop varieties depleting ecological biodiversity, risking the creation of barren lands. Farmers may become dependent on big biotechnology industries for seeds rather than traditional storage methods or buying herbicides or pesticides. Smaller estates may fold in the face of these vast food-growing corporate machines.
Enormous fields of one seed type become very exposed to pests. Pests frequently develop resistance to pesticides, leading to constant tinkering with plant DNA to stay ahead of the game. Viruses and other pathogens may also interact with modified plants, potentially creating newer and more robust versions of themselves.
Added nutrients could reduce a modified plant’s secondary benefits or create new allergens and toxins. Some GE crop toxins are already present in people’s blood. Many long-term effects of GE crops are unknown. The drive for profit from the land doesn’t necessarily consider what each area of land needs.
The same is true for human genetic engineering. Altering our DNA may cause unforeseen harm to our bodies and minds. Eradicating diseases and genetic disorders is a worthy cause, but it ignores the ethical and moral debates about reengineering the human race.
Governments or big businesses could abuse their position, with many long-term unknowns about genetic engineering. Affordability could also mean rich people could afford “designer” babies, while less affluent people may miss out on possible advances in genetic therapies.
Many people also think humankind should not be playing God, neither with our bodies nor animals or plants, who have no choice in the GE we are imposing on them.
Of course, most biotechs run for profit as much as benevolence. A cancer cure would be a remarkable breakthrough. What would people be willing to pay? A private biotech company will surely set the ticket price high. Does biotech operate for the benefit of humankind or for profit?
Biotechnology: Changing the Future of Humankind
Biotechnology harnesses cutting-edge science to examine the natural structures of humans, animals, and plants. These genomes, or DNA, offer insights and answers to why our bodies work, or fail, and possible solutions to burning issues like the cure for cancer.
Biotech seeks to improve our health and happiness by creating reliable food sources that suit our continually growing demands, finding medicines for our ills, and maximizing our energy sources. It is advertised as a natural solution to modern-day ills, some of which are our own creations.
Ethical debate swirls around biotechnology and the power scientists wield in the laboratory, potentially over people’s lives and even that of the planet. Wildlife and diversity could suffer from homogenized plants.
That said, transgenic cows are now expressing modified milk that may counter disease. Meanwhile, much of the food Americans eat already comes from genetically engineered crops, creating, in effect, an enormous long-term global human experiment. We’re paving a new road, but no one knows the destination or the obstacles we may be placing in front of ourselves on the way.
