Today was the perfect day for Hadiah to make her first forays out into the outdoor tiger exhibit. She rambunctiously played, sniffed and rolled around in the bushes while visitors looked on. Only around 400 Sumatran tigers still exist in the wild; each birth is cause for celebration to help keep genetically viable populations intact. How can you help tigers? Watch what you buy (for example, plam oil, which is in thousands of products, comes primarily from Indonesia where forests are being destroyed to plant palm oil plantations, so look for foods and products that do not contain it); don't buy exotic wood products that aren't from certified sustainable forestry practices; donate to organizations helping to conserve tigers and their habitat.
