Prescribed burning is a tool used in forests and wildlife preserves across North America and Australia. In a prescribed burn, fire – management workers intentionally set fire to part of a forest and let the fire burn under supervision until it dies out naturally. Supporters of regular, prescribed burns claim that the practice of setting regular, controlled fires decreases the likelihood and severity of natural forest fires. However, opponents point out that this benefit is not worth the dangers that result from prescribed burning.
First, prescribed burns pose a threat to wildlife in the forest where the burn is being conducted. Birds, deer, and other animals may become trapped in the fire and die. This is especially true if there are nestlings, young birds that are not yet ready to leave their nest, or any type of young mammal that is too underdeveloped to run quickly; such creatures would not be able to escape, even if a mature animal could.
Second, as all fires do, prescribed burns release smoke that pollutes the atmosphere. Smoke from fires contains carbon dioxide and other greenhouse gases that can trap heat in Earth’s atmosphere, and chemicals in the smoke can contribute to acid rain and other forms of pollution. Furthermore, winds may carry the harmful chemicals to areas far away from the actual fire. In this way, prescribed burns increase pollution levels.
Third, in many areas where prescribed burns are used, natural fires still break out and cause damage. So after spending the money, time, and resources to perform a prescribed burn, firefighters and residents may have to spend additional money, time, and resources fighting the natural fires that prescribed burns failed to prevent.

One traditional method of classroom instruction is lecturing. Lecturing involves the teacher talking about a topic for an extended period of time, expecting students to learn by listening attentively. Today, some educators believe that teachers should limit how much time they spend lecturing and instead teach by encouraging in – class discussions and having students work in groups. However, some teachers still teach primarily by lecturing. Do you believe lecturing is an effective teaching method?

I believe lecturing can be an extremely effective way for professors to teach if they have strong communication skills. Some of my most memorable classes have been taught by brilliant lecturers who captivated me with their engaging speaking style, ability to explain complex topics clearly, and passion for their subject matter.

I don’t think pure lecturing works as well as teaching methods. Without student participation, teachers have no way to assess if students actually comprehend the material. Students can zone out during long lectures if they are just passively listening. Active learning through discussions, activities, and questions lets students engage with content and teachers identify gaps in understanding.
