Every year, millions of people descend on protected and pristine natural areas to observe rare species. However, a new report casts doubt on the value of this form of tourism. In fact, it suggests that ecotourism is more damaging than helpful to nature. Details are in a report published in the journal 'Trends in Ecology and Evolution'. Researchers believe tourists are disrupting animals in their natural habitat. They pointed to a recent event where sea turtles in Costa Rica had problems laying their eggs because of the hordes of tourists who had congregated to watch the turtles' nesting habits. The report says that ecotourism is making animals bolder and that this could endanger the animals. A regular human presence might make animals tamer and less cautious about other animals around them, and this could put them at risk of being attacked by their natural threats. "Then they will suffer higher mortality when they encounter real predators," the report says. It added: "When animals interact in 'benign' ways with humans, they may let down their guard." The report said it was essential, "to develop a more comprehensive understanding of how different species in different situations respond to human visitation and under what precise conditions human exposure might put them at risk." 22 C 23 D 24 D 25 C 26 B An association of local governments in the UK, called the LGA, has warned consumers about the use of some skin- lightening creams. The LGA discovered that some of the whitening cosmetics they tested contained banned ingredients and were thus illegal. However, they were available for purchase in UK stores. An LGA spokesperson said these ingredients could pose a serious threat to consumers' health. He said there has been an increase in the number of users experiencing health problems after using the creams. These include seizures, rashes and scarring. The spokesperson said the creams could increase the risk of skin cancer, and liver and kidney damage. The global skin-lightening industry is booming. In 2017, it was valued at an estimated $4.8 billion and is forecast to nearly double to around $8.9 billion in the next decade. Many people use it to reduce the darkness of the color of their skin. The LGA warned that "rogue retailers" were selling illegal skin-lightening lotions on which the label incorrectly listed the ingredients and omitted the illegal substances. The LGA said some illegal ingredients acted like paint stripper and could burn off the top layer of skin. It said: 27 D 28 C 29 C 30 A
