The evidence from the International Panel on Climate Change is in, and the overwhelming scientific consensus is that yes, human activity is harming the planet and warming the Earth,  Greenhouse gases have been produced by humans and industry in such large volumes that we have triggered a shift in global climates.

This is no fun to admit, as it means we must change the way we live, or face environmental and human consequences that are frightening to behold.

I think that the answer is yes to both questions.  As others have pointed out, human activity does both make it a better place for humans to live, and there are some things we have done that harm the planet.  I would argue, though that part of what we do is we learn about how ouractivities affect the animal life and the world around us in general.  The more we learn, the more we can do to create a sustainable world, where humans live in comfort and we are eco-friendly.  I think, like in most things, that there is a balance.  I also think that we are getting closer to finding that balance, because our activities are not JUST limited to enhancing our own comfort.  We are trying to study the world around us and learn about our effects on it.  That being said, however, I think that human lives are worth more morally than animal lives.  (I sure do like a nice hamburger every now and then!)  We will probably never create a perfect Utopia where everyone lives in peace and we are not harming the environment in any way, but we can strive to do better.

It makes it a better place for HUMANS to live, but this could very well be in the short term. We haven't exactly made things better for a lot of other animal, and plant species. We have decreased the diversity of life on earth, and less diverse ecosystems are in general less healthy ecosystems. There is no question we have done things to the planet that we may not even be able to understand. Who really knows what will happen as a result of the huge island of trash that is floating around the Pacific, for example?

Yes to both.

Of course some things people are doing hurt the planet.  If you believe in global warming, like most scientists do, that's the most obvious example.  But there are others, such as all the runoff from agricultural chemicals that goes down the Mississippi and creates a huge dead zone in the Gulf of Mexico.

Of course human activity makes earth a better place for humans to live.  I would not like to live on a planet where human activity hadn't killed off most of the large predators (anyone like to run away from a sabertooth tiger or a grizzly bear)?  We've also managed to make it so we can live through winters in comfort, etc.

So the problem is making sure we don't harm the planet too much.  And it's hard to know at what point that happens.
