I just love my Black Labrador Retriever. Even if he’s asleep in his favorite spot in front of the TV, if I go to the kitchen, he gets up and follows me there. He just always wants to be close. Every day I take him for a long walk in a nearby park, and as often as I can, I drive out to a local pond, where he can swim. I throw sticks for him over and over. I get tired long before he does. 1)Life of the universe 2)Social responsibility 3)Useful and beautiful 4)Mutual interests 5)Caused by climate change 6)Man’s influence on climate 7)First astronauts
