There are many factors that can make recognizing a bias hard, but one of them is if we have the same bias.
Say for example, that one person thinks that taller people are smarter and they listen to a speech that makes the same statement - they can then think that it's just confirming what they know, and can be a real fact instead of their bias. This will make it harder for them to recognize the bias.
Drilling oil wells reduces deforestation. The oil extraction process results in the release of toxic drilling by-products into local rivers, while broken pipelines and leakage result in persistent oil spillage. In addition, the construction of roads to access remote oil sites also signifies take trees out of the way.
Deforestation reduces the habitat for millions of species. Eighty percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes. It also affects climate change. Forest soils are moist, but without protection from sun-blocking tree cover, they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor to the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts.
