It is humanity's duty to treat with utmost respect the only planet we (and our future generations) seem to have for the time being. This of course includes animal life. But the impact of human growth upon the environment and animals is inescapable. We are decimating fish, creating more meat than is naturally possible, and destroying natural habitats. This is, of course, very sad. As for going vegetarian and all that, the bigger problem is eating meat from the mega-slaughterhouses which have nothing but profit on their minds. Eating meat is a personal choice, but if you take your duties seriously, especially about about how the animals are treated and where your food comes from, consider spending a little more money to buy organic meat?
