The correct answer is - False.
The funding for the preservation of the forests should be equally distributed for all the forests on the planet. The tropical rain forests are the thickest, the ones that have the largest biodiversity, and they are the ones that produce the highest levels of oxygen, but that doesn't mean that they are the only ones that need protection. The largest forests in the world are actually not the tropical rain forests, but instead it is the taiga, stretching from Scandinavia, throughout all the length of Russia, and throughout all the length of Canada. The mid latitudes are covered with deciduous forests, and they play a crucial role in this parts of the world, both in cleaning the air, providing oxygen, as well as supporting the ecosystems.
