It’s obvious by now that humans are making an impressive impact on the planet. Unfortunately, it’s not a positive one. You might not be worried about what’s happening, but the effects are being felt right now, and it’ll only get worse as time goes by. The repercussions will affect generations to come too. Just look at this photo, which shows the level of pollution in Mexico City. When you add that with the ever-growing population, you get how this area has become inhospitable for animals in the region.
