Today in our environmental science lecture, we'll discuss the impact of urban green spaces. A recent study in Melbourne found that increasing tree coverage by 20% could reduce local temperatures by up to 2 degrees Celsius during summer. Interestingly, the study also showed that parks with native plants attracted 30% more bird species than those with exotic species. However, the researchers noted that the main challenge is not planting trees, but maintaining them during droughts. Therefore, they recommend using drought-resistant species and implementing smart irrigation systems. The city plans to allocate 15% of its annual budget to this project over the next five years.
