A major threat to the Bengal tiger is climate change. Climate change harms the tiger because the rising sea level causes dirty saline water to run into the tiger's drinking water and this causes them to become sick and die. Also, the higher water level has led to less tiger habitat because it has reduced the size of the Sundarbans forest. Changing the light bulbs in your house will result in less use of electricity which means less fossil fuels being burnt. This will reduce carbon emissions and thus slowly stop climate change. By stopping climate change, the sea level won't rise and be a major cause of tiger deaths. By taking this pledge you can help save the amazing Bengal tiger.
