Deep introspection

Had a bout of deep introspection after watching 'Rise of the Planet of the Apes'. The actions done during the active lifetime (30-40 years) of a single man / woman, aggregated collectively as by the human race, impact not just immediate family  (of the individual), but the whole ecosystem (of other sentient beings and not). The individual may have a short sight of those 30-40 years, but the balancing system will take a broad view of like probably 200 years - pre & post industrialization.

Is Global warming real or unreal ?
Is animal testing good or bad ? do benefits outweigh the ethical concerns ?
Did we stop increasing our intelligence and other species / genus are catching up ?

Re: the famous quote in Matrix by Agent Smith ? "Human beings are a disease, a cancer of this planet...Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet. You're a plague and we are the cure. "

I am not strong on the above views but what else also I am not sure about is what's going on: What's the state of the planet some 20,000 km above.

Are we good to the place we call as home ?

UPDATE: June 16th - read that never in the history of earth, we had 400ppm other gases...due to the global warming. We had a peak of 296ppm which we crossed... there have been 8 ice ages on earth, maybe this 400 is the harbinger of the next one.... god (or creator) knows.....
