Big Think - We have the tools to fix our food system. Why aren’t we using them? | Hannah Ritchie
The current food systems significantly contribute to environmental issues such as deforestation, biodiversity loss, and water pollution. They account for about a quarter of global emissions, primarily through land use changes and emissions from farming activities. To address these challenges, two main goals are identified: providing a nutritious diet for everyone and minimizing environmental impact. Despite producing enough food globally, inefficiencies such as meat production, biofuels, and food waste lead to significant losses. Improving agricultural productivity and changing dietary habits are key solutions. Increasing crop yields through better technology and practices can close existing gaps, especially in regions like Africa. Shifting diets away from meat and dairy towards plant-based foods can reduce environmental footprints. Meat substitutes and reducing meat consumption incrementally can also help. Vertical farming offers potential but is currently not economically viable for staple crops. By implementing these solutions, we can sustainably feed a growing population while reducing environmental impacts.
Key Points:
- Food systems contribute significantly to climate change and environmental degradation.
- Improving agricultural productivity can close yield gaps and increase farmer incomes.
- Shifting diets from meat to plant-based foods can reduce environmental impact.
- Vertical farming is promising but not yet economically viable for staple crops.
- Incremental dietary changes can have a larger impact than a small percentage going vegan.

3. 🌾 Increasing Agricultural Productivity
- Researchers identify a significant gap between attainable yields using best practices and current yields achieved by farmers.
- Improving access to technologies like improved seeds, fertilizers, pesticides, and irrigation can close this yield gap.
- In Africa, crop yields have increased over the last 50 years but remain significantly lower than global averages.
- Investing in agricultural technologies not only enhances environmental benefits but also increases farmer income and yields.
- Higher yields can help farmers, especially those near or below the international poverty line, achieve greater income and lift them out of poverty.
- This is particularly important in regions with high population growth, where increased food production is crucial.
- For example, in Kenya, implementing drip irrigation and high-yield seed varieties has increased maize yields by 30%.
- In India, adopting integrated pest management (IPM) techniques has reduced pesticide use by 50% while increasing crop resilience.
- These solutions contribute to not only closing the yield gap but also to sustainable agricultural practices.
4. 🥗 Dietary Changes for Sustainability
- Reducing meat and dairy consumption is crucial for lowering environmental footprints, including carbon emissions, land use, water pollution, and biodiversity loss. Plant-based foods generally have a significantly lower environmental impact compared to animal-based products.
- Carbon emissions from plant-based proteins can be 10 to 50 times lower than those from high-emission meats like beef or lamb. This significant reduction in emissions highlights the environmental benefits of adopting a plant-based diet.
- Different meat products have varying carbon footprints, with larger animals typically having higher emissions. Beef and lamb are particularly high-emission meats compared to chicken or pork.
- Calorie efficiency measures the calories returned from animal products compared to the calories fed to the animals, highlighting inefficiencies in animal farming. Animal farming is often inefficient as it requires more calories to feed animals than the calories they produce, emphasizing the environmental benefits of switching to plant-based proteins.
- Specific plant-based alternatives, such as lentils, chickpeas, and legumes, provide nutritional benefits with minimal environmental impact, making them ideal substitutes for high-emission meats.
5. 🐄 Efficiency of Animal-Based Foods
- Animal-based food production is highly inefficient in calorie conversion: cows convert only 2% of the calories they consume into meat, lambs 4%, pigs 9%, and chickens 13%.
- Protein efficiency for animal-based foods is slightly better but still low: cows, lambs, and pigs convert less than 10% of consumed protein into meat protein, while chickens convert less than 20%.
- A well-planned plant-based diet can meet most nutritional needs except for vitamin B12, which requires supplementation.
- Transitioning to plant-based diets can be challenging; thus, investing in meat substitutes that mimic the taste, texture, and nutrition of real meat is crucial.
- Small reductions in meat consumption (10-20%) globally can have a greater positive impact than a small percentage of the population going fully vegan.
- Traditional farming methods are not scalable to meet the demands of a global population of 8-10 billion people; innovative and sustainable solutions are required.
6. 🌿 Innovations in Agriculture
- Vertical farming offers significant benefits like reduced land use and minimized pesticide needs. However, it faces economic challenges due to increased energy demands. With current energy prices, producing staples like cereal crops becomes economically unfeasible, potentially driving the cost of a loaf of bread to $18, six times the normal price.
- The economic struggles of many vertical farming companies, exacerbated by rising energy costs, underscore the need for more efficient energy systems to make vertical farming a viable solution.
- Despite global food production exceeding needs, nearly 10% of the population remains undernourished due to distribution issues rather than production limitations, highlighting a misalignment that vertical farming alone cannot resolve.
- Strategies like closing yield gaps and altering diets could help increase food availability without solely relying on vertical farming innovations.
- Climate change poses a threat to traditional farming viability in certain regions, necessitating preparedness measures to ensure food demands are met now and in the future.

- Past hormonal methods, like the 2011 trial with progestin and testosterone, were effective in sperm production reduction but halted due to side effects such as severe acne and mood swings.
- Unlike female contraceptives, male contraceptive side effects are judged without considering the health risks of pregnancy, presenting a higher barrier to acceptance.
- Recent advancements include a 2023 discovery of a compound that immobilizes sperm, tested successfully in mice, highlighting potential for non-hormonal male contraceptives.
- Currently, a male birth control pill is in early clinical trials, and a gel using progestin and testosterone is in advanced testing stages. The gel, applied on shoulders, effectively reduces sperm production.

9. 🔗 Permanent Birth Control Options
- Individuals with a uterus can opt for permanent birth control methods such as tubal ligation, where the fallopian tubes are closed or removed, or a hysterectomy, which involves removing the uterus entirely.
- Those with a penis can choose a vasectomy, a procedure that surgically cuts or blocks the vasa deferentia to prevent sperm from being included in ejaculation.
- These procedures are highly effective, with less than 1% chance of pregnancy post-surgery, but they involve risks such as surgical complications and potential regret.
- Medical professionals often exhibit reluctance to perform these procedures, especially for younger patients, due to the permanence and possibility of future regret.
- Patients should consider factors such as their age, future family planning desires, and potential for changing personal circumstances before opting for these procedures.
