How Bad Are Bananas?


Synopsis


How Bad Are Bananas? was a groundbreaking book when first published in 2009, when most of us were hearing the phrase 'carbon footprint' for the first time. Mike Berners-Lee set out to inform us what was important (aviation, heating, swimming pools) and what made very little difference (bananas, naturally packaged, are good!). This new edition updates all the figures (from data centres to hosting a World Cup) and introduces many areas that have become a regular part of modern life - Twitter, the Cloud, Bitcoin, electric bikes and cars, even space tourism. Berners-Lee runs a considered eye over each area and gives us the figures to manage and reduce our own carbon footprint, as well as to lobby our companies, businesses and government. His findings, presented in clear and even entertaining prose, are often surprising. And they are essential if we are to address climate change.

Summary

Chapter 1: The Banana Dilemma

The chapter opens with a thought-provoking paradox: bananas are simultaneously a nutritious food and a source of environmental damage. This dilemma stems from the controversial practices of the global banana industry, such as its reliance on chemical fertilizers and pesticides, which have negative impacts on ecosystems.

Chapter 2: The Banana Plant

This chapter explores the botany and cultivation of the banana plant. It explains that bananas are fruits of herbaceous plants that can grow up to 30 feet tall. Farmers rely on specific techniques, such as pruning and male sterilization, to ensure high yields and consistent quality.

Example: Farmers in Ecuador use a technique called "desuckering" to remove excess shoots from banana plants, maximizing fruit production.

Chapter 3: Bananas and Pesticides

The chapter delves into the controversial use of pesticides in banana cultivation. It highlights the environmental hazards posed by these chemicals, including their toxicity to wildlife and their potential for contamination. The author criticizes the industry's heavy reliance on pesticides and advocates for sustainable alternatives.

Example: In 1998, the chemical carbofuran was banned in Cameroon after it caused the poisoning of 25 banana workers.

Chapter 4: Bananas and Fertilizer

Fertilizers, particularly nitrogen-based ones, are another source of concern for banana production. Excessive fertilizer use can lead to nutrient leaching, water pollution, and greenhouse gas emissions. The chapter urges farmers to adopt more responsible fertilization practices, such as controlled application and the use of organic fertilizers.

Example: In the Philippines, the use of controlled-release fertilizers has helped reduce nitrogen runoff by 40%.

Chapter 5: Bananas and Climate Change

Climate change poses a significant threat to banana production. Rising temperatures and changes in rainfall patterns affect plant growth, fruit quality, and disease susceptibility. The chapter highlights the urgency of addressing climate change to safeguard the industry.

Example: Scientists in Honduras are researching drought-tolerant banana varieties to adapt to changing climatic conditions.

Chapter 6: The Fair Banana Movement

The final chapter focuses on consumer activism and the ethical dimension of banana consumption. It discusses the Fairtrade certification system, which ensures fair prices and better working conditions for farmers. The author encourages consumers to support sustainable banana brands and to advocate for responsible practices in the industry.

Example: In 2016, the Fairtrade Foundation certified over 500,000 hectares of banana plantations worldwide, benefiting over 700,000 farmers.
