On what island is Manilla, the capital of the Philippines, located?

Explanation

Luzon is the largest island in the Philippines and home to the capital, Manilla. On the southern part of the island there are several, still active volcanoes. Around 46 million people live on the island, which covers an area of 106,000 km2. Many of the trees on the island have been felled, and therefore, between 1990 and 1992, a project started to protect the biodiversity of the island. The Sierra-Madre woods are home to 78 bird species that are indigenous to the Philippines.
