Tourism based on wildlife is a key industry for Namibia and other African countries, as it contributes both to the economy and nature conservation. However, travel for tourism purposes is responsible for around 8% of global emissions, which contribute to global warming and climate change. So while we need tourism to create jobs and sustain wildlife areas, we must also try to reduce the impact of travel on the environment. 
Tourism in Namibia in particular, requires driving long distances to take in all of the varied landscapes and natural attractions. Many tourism companies and self-drive tourists use fuel-heavy 4x4 vehicles to access remote parts of the country. The long road trips through desert landscapes and 4x4 driving challenges encountered on rocky mountain passes or in the deep sand of the Kalahari are key attractions for adventurous visitors to Namibia. Electric 4x4 vehicles may be a possibility in future, but what can we do right now to reduce carbon emissions from the tourism industry? The good news is that trees naturally use carbon dioxide in the atmosphere to grow. Planting trees is thus a simple way to offset our carbon emissions and help lessen the impact of the tourism industry on global warming. Besides producing oxygen, trees provide shade, food and shelter for a host of different animals and also humans. Fruit trees are especially valuable where people cannot afford a high quality diet, while indigenous trees can help restore the environment around urban areas without using too much water.
