Bangladesh's floating gardens began hundreds of years ago.The gardens are made from native plants that float in the rivers and operate almost like rafts(筏), rising and falling with the waters.Historically, they were used to continue growing food during rainy seasons when rivers were filled with water. The farmers layer the plants about three feet deep, creating a version of raised­bed gardens that float in the water.Then, they plant vegetables inside those rafts.As the raft­plants rot away, they release nutrients, which help feed the vegetable plants. But as climate change affected the volume of water in those rivers, the researchers wanted to understand whether Bangladesh's floating gardens could be a continuous farming practice.They interviewed farming families and found strong evidence that floating gardens provide stability, both in the amount of food available to feed rural populations and in a farming family's income. They found that farmers typically used hybrid(杂交植物) seeds, which must be repurchased each year, to grow a diverse range of vegetables in the floating gardens.　The gardens were also sensitive to pests, so farmers ended up spending some money on both pesticides and fertilizers.But even with those expenses, they found, benefits outweighed costs.One farmer told the research team that he earned up to four times as much money from the gardens as from traditional rice fields. However, before gaining profits, farmers often take out high­interest loans(贷款) to cover the investment costs of filling the beds and stocking them with plants.Luckily, there are also lower­interest loans from responsible government or non­governmental organisations, which could ease that burden. 1．How do vegetable plants gro
