Burning fossil fuels releases carbon dioxide into the atmosphere, which is a greenhouse gas. Increased greenhouse gases caused an increase in average global temperatures, known as the greenhouse effect. This is linked to climate change. Some areas of the world are getting wetter and others hotter and drier, and these changes have an impact on ecosystems and biodiversity. For example, warmer weather in the Arctic and the subsequent melting of the sea ice has an effect on animals that are living there. The polar bear is no longer well adapted for living in its habitat and is an endangered species. Humans also require resources. Large areas of forests are cleared to make more room for agriculture, or to mine minerals, or for growing other resources like palm oil. The removal of trees is called deforestation and has an enormous impact on not only the local ecosystem but the entire planet. Ancient forests such as rainforests are unique ecosystems. They can support a high biodiversity and are home to species that can only live in that habitat. For example, in Borneo, rainfor ... ...
