In recent years, the rapid development of China has also caused great damage to the environment. "Developing low-carbon economy and protecting environmental resources" is a national policy put forward in view of this situation. So in order to meet the needs, many lectures are also popular, but it is hard to say that some lectures don't follow the trend. As you said, some lectures are really not very good. No matter what the lecture is, the key lies in our actions, how to start from ourselves and take active actions to protect our environment bit by bit, so as to achieve practical results. As a citizen, patriotism is a basic political accomplishment. Patriotism in "developing low-carbon economy and protecting environmental resources" is patriotism of protecting the environment with actions, not patriotism of slogan in lectures. Therefore, we should not only attend lectures, but also go out of the box of lectures, use our own environmental literacy actions to develop low-carbon environmental protection, and at the same time play a leading role to awaken more people's environmental awareness and lead more people to the road of protecting environmental resources.
