There are millions of lakes on our planet. Many are quite large such as the Great Lakes in our country and Lake Victoria in Africa, but one-third of the world’s standing water is contained in lakes and ponds of 25 acres or less. Many of these lakes are found in remote, often mountainous areas with no inflow and outflow. Nevertheless, in most of these lakes there are fish.
One of the arguments some people make when discussing human causes of climate change is that people can’t cause such massive changes. However, there is a long historical record of human-driven ecological and climatic change in Europe, North America and New Zealand, among other places.
