A: I think some people take environmental problems seriously enough, for example, to recycle their rubbish appropriately. But still, so many people are using energy and buying plastic products without any further consideration of the impact of their actions. We all know that the world’s natural resources are shrinking at an alarming rate, but no one seems to actually feel it's their duty to change the way they live. So, I guess, since we all share the responsibility to protect the earth, we should act now as a whole and do more green activities, like stopping the use of plastic products.

我认为有些人足够重视环境问题，例如，适当回收他们的垃圾。但是，仍然有很多人使用能源，购买塑料产品，而没有进一步考虑他们的行为的影响。我们都知道，世界上的自然资源正在以惊人的速度减少，但似乎没有人真正感到自己要对改变自己的生活方式负责。所以，我想，既然我们都有责任保护地球，我们现在应该作为一个整体行动起来，做更多的绿色活动，比如停止使用塑料产品。
