Introduction
Climate change is one of the most serious environmental challenges of the 21st century. It is mainly caused by human activities such as burning fossil fuels, deforestation, and intensive agriculture. As a result, global temperatures have increased, and natural systems are changing faster than many species can adapt.
Climate change affects not only weather patterns but also the survival of plants and animals. Rising temperatures, changing rainfall, melting ice, and extreme weather events place strong pressure on ecosystems around the world. Many species lose their habitats, struggle to find food, or face new diseases.
In this learning unit, students explore how climate change leads to species extinction and damages ecosystem health. They learn why biodiversity is important and how ecosystems support life on Earth, including human life. The unit also introduces conservation strategies and shows how protecting nature can help both people and the planet.
To support understanding, the unit uses Augmented Reality (AR) through Delightex. AR helps students visualize ecosystems, species interactions, and environmental changes that are difficult to observe in real life. This makes learning more engaging and meaningful.
