Did you know that one tiny addition to a very large park can change the entire ecosystem of that large space for the better? In Yellowstone National Park, people reintroduced wolves, and those wolves made this place a beautiful, thriving, area of the world. These wolves made the deer population go down, which caused the plants to get the chance to grow, which caused more and more animals to be able to succeed. The trees grew, and this caused the rivers to thin, and become more controlled. I believe that humans should reintroduce wolves to more places. If you sign this change.org petition, it will get the message across to the government and others that this is a cause that many people care about. If your morals are in the right place, you will know that the environment is one of the best things to invest in (even if it’s just 10 seconds of your time).
