for my team, all days are days of the earth, our contributions to the world are from planting thousands of trees, doing scientific research focused on the wild life conservation, releases animals to the wild life, fighting for bullfighting abolition, and promote the nonhuman animals rights, however, for me the earth day was a very sad day, that day I received a call from someone telling me that there was a "rat" who was lying on the street and she don't know what to do, so I? immediately went to see what was the matter, when I arrived, I realized that it was a opossum, who was dying, he was allegedly tortured and ultimately had killed by a big stone thrown in your body, the reason for this act was the cruelty, ignorance and cowardice of some people, that day fill me with tears to see that it was actually a female opossum, and was breast of 7 offspring  that came out of his abdomen, I tried with all my soul to give him first aid to the opossum mom but just hugged my hands and died, leaving their children unprotected, later, take to me the offspring possum and ran to the veterinary clinic from my city, however, also died in a few hours, the doctor telling me that the offspring had only a few hours old, had not even opened their eyes, these inhumane actions are the reflection of the great mission and responsibility as agents of change, the world, animals, plants and life we need our help, we must strive more and help the planet, the death of the opossum mom will not be in vain because I will strive more, more and more to help the nature...
