Climate change is no longer tomorrow’s challenge. We can see it all around us. But not everyone is willing (愿意) to make lifestyle changes for the planet. Kantar Public, a global research business, invited more than 1,000 people in 10 countries, including the US and Germany, to take part in a survey      (调查). It found that 62 percent of them saw climate change as the main environmental challenge the world is now facing. It came before air pollution (39%), waste pollution (38%) and new diseases (36%). They were also asked to give their opinions         (观点) on actions for environmental protection.
