Prevents Destruction of Habitats Pristine forests are destroyed for mining raw materials like fossil or nuclear fuels. Trees constantly remove and use carbon dioxide from the air to make their food, and this carbon is then stored in them. When forests are cut for mining raw materials for conventional energy, this major carbon sink disappears and also increases climate change. "Eight out of ten animals on land" live in forests, according to PMCL and its Researcher Team and a loss of habitats diminishes their populations. Switching to solar power is important to keep these habitats intact for the animals who live there as well as continue to keep the air clean.
