Фрагмент из книги:
Farmers in developing countries are some of the most vulnerable people on earth, prey to world commodity markets, middle men and the weather. So-called 'fair-trade' arrangements guarantee co-operative groups a price above the world market and a bonus on top. The growing fair-trade market has distributed hundreds of millions of pounds to more than 50 million people worldwide. But critics say that fair trade will never lift a country out of poverty; indeed, it may keep it there, because the money generated from sales goes almost in its entirety to rich countries which promote the products. As a simple guide, only about 5% of the sale price of a fair-trade chocolate bar may actually go to the poor country.

Our times.
Since 1950, the global population has grown at up to a hundred times the speed it grew after the invention of agriculture, and ten thousand times as fast as it did before that. This is a great human achievement. The huge increase in population in the last century, and continuing in this, however, is a problem caused by success the success of vaccination and clean-water programmes, and of the ‘green revolution in agriculture. Without the latter, it has been estimated that mankind would have needed extra farmland the size of North America to feed itself. To put it another way, some two billion people are alive because of it. Yet most observers believe so many billions of humans are too many for the planet to sustain indefinitely; we need too much water, we consume too much carbon-based energy, and we take over too much land to feed ourselves, for the biosphere to cope.

By far the best known problem in our world today is climate change. This is mainly caused by the burning of fossil fuels, which results in the production of greenhouse gas. This stops the planet cooling itself as efficiently as it needs to, thereby raising temperatures. By how much and exactly with what effect are unknown. An increase in ‘wild’ or unpredictable weather patterns may be one of the consequences. Looking at possible projections, this is either a problem rather over-stated today and which can be dealt with by greener ways of regenerating energy; or it is an imminent catastrophe that could make this the last human century.
