Hmmm… JazzysMom-- it is our planet, yes but that's about the extent to which I agree with you. I don't think pollution is as much of a problem for wildlife as habitat destruction is...
An example- my parents own 25 acres in the mountains. I went to visit them this past weekend and I know their neighbor has beavers on his property. I was so excited to have a chance to see them up close; on my last visit I only got to see the pencil shaped tree trunks and their house- but this time I really wanted to wait for a siting. Unfortunately I found out that they had created a dam that flooded the property so the land owner had them trapped and then killed. For what?? Doing what beavers do?! The land owner has acres upon acres of just woods and lakes and streams. Did he really NEED to remove the beavers because they were doing THEIR thing? I don't know. I just think that was unnecessary. That is the kind of thing that irritates me. Why is it OUR land and not theirs? They had probably been in those woods for ages... but no, it's OUR land now. But they were wrecking OUR land and OUR gardens and OUR things...
And sure, the environment changes and makes food sources scarce from year to year but what about all the roads they have to cross to find the shrinking food supplies? They're bound to get squished with any step they take. And heaven forbid they come within 30 feet of a house... PEST we scream! Quick, call someone to take it out!! We're the greedy ones. Want, want, want... it's all ours! None for you! If we wanted to 'share' the land/environment/planet we'd be more like the Native Americans...IMO of course.
(Not trying to attack anyone, but I have a BIG heart for creatures who cannot help themselves)
