When we talk about rights, it's only valid if we assume humans are superior to all other life forms on this planet. That we have more rights than other creatures. Some people will say that clearly we are superior, but when it all comes down to it, what do we give this planet that other creatures don't that isn't negative?

Using this as a base, and assuming we're another organic form that will simply return to dust in the end, it's possible to argue that human beings infringe upon the rights of practically all other living creatures by their very existence. Or don't other creatures have rights?

My weedkiller infringes on the rights of the dandelions in my yard. And I like it that way. :)
