Environmental Problems in Macau! This morning, after taking my daughter to school, I returned by climbing the trail up to Taipa Park 大潭山. As I was walking along the section that is closest to the chimneys of the Incinerator, I came across dead frogs (toads?) on the trail. I did not count the exact number, but estimate around 20. All were fully grown and were healthy until recently. But they were all face down, dead, with excreted fluid coming out of their mouths. Here's a picture of one: Other pictures can be found here As I walked further down the trail, about 100 meters from where I saw the first frog/toad, I didn't see anymore. If anyone knows why they died, or what could have caused their deaths, it would be appreciated.
