Nowadays, there is no doubt that our world is gradually changing every day, partly affecting the lives of thousands of creatures on Earth. This leads one to wonder whether the disappearance of species of plants and animals is the most major environmental concern while there are a number of considerable issues which should be paid more attention to. I believe that these problems such as climate change and radioactive waste are more critical, therefore, authorities should consider them as high-priority issues that need to be addressed.
