Our environment changes due to both natural causes and human activities. Natural causes include volcanic eruptions, ocean currents, solar variations and greenhouse gases, while human activities such as burning fossil fuels, deforestation, industrialization and population growth enhance the greenhouse effect and contribute to issues like global warming, pollution and loss of habitat. Maintaining a sustainable relationship with our planet requires understanding both how nature impacts the environment and how human choices also make a difference.
