Can Planting Trees Reduce Air Pollution? | CBCGDF Climate Change Working Group

Planting trees has long been considered a potential solution to reducing air pollution, and it indeed has several positive effects.

Trees act as natural air filters. Their leaves can absorb various pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides. Through the process of photosynthesis, trees also take in carbon dioxide, a major greenhouse gas, and release oxygen, thereby improving air quality.

 

However, the effectiveness of tree - planting in reducing air pollution is not without limitations. The type of trees matters. Some tree species are more efficient at absorbing pollutants than others. Also, the location of tree - planting is crucial. Trees planted in urban areas with high pollution levels may face challenges such as limited space for growth and exposure to other harmful substances that can affect their health. Moreover, while trees can help reduce certain pollutants, they may not be sufficient to combat all sources of air pollution, especially in highly industrialized regions where emissions from factories and vehicles are extremely high. In summary, planting trees can contribute to reducing air pollution, but it should be part of a comprehensive strategy.

Unveiling the Mysteries of Cetaceans in the South China Sea: Chinese Scientists Describe Important Marine Mammal Areas (IMMAs)

Image
The world’s ocean ecosystems are facing mounting threats—climate change, marine pollution, overfishing, and habitat destruction due to human activities, to name a few. These pressures are particularly dangerous for marine mammals like cetaceans, whose survival hinges on healthy habitats and stable populations. Yet, in regions like the South China Sea, where biodiversity is exceptionally high, little research has been done to understand the needs and habitats of cetaceans. This lack of data has left a gap in our knowledge and made it challenging to establish targeted conservation strategies. Recognizing this, Chinese scientists have now set out to fill these gaps and contribute essential data to inform future policy and management, aiming to protect these vulnerable species and support the objectives of the Kunming-Montreal Global Biodiversity Framework (GBF). In a landmark study published on October 8, 2024, in Biological Conservation, Dr. Li Songhai and his team from the Institute of...
