Explanation:

1. El desarrollo humano, como la tala de árboles, la creación de nuevas fincas y fábricas, está cambiando rápidamente el bosque lluvioso amazónico, lo que lo somete a riesgo.
2. Las plantas en el bosque lluvioso absorben dióxido de carbono. Al cortar los árboles y reemplazar los bosques, menos dióxido de carbono es absorbido.
3. El hecho de que algunas tribus sean nómadas y otras estén sedentarias muestra diferencias en sus formas de vida y culturas.
4. La búsqueda de recursos como cultivos (bananos, caña de azúcar), petróleo y gas, y la tala de árboles por madera, muestra que la razón principal por la que los humanos están cambiando el bosque lluvioso es el deseo de más recursos.
