I think the two are related and when we decide to take better care of the planet we will take better care of each other and as long as we continue fighting and destroying each other we'll do the same to the planet.

I don't need to do research. I don't need to use Google or Wikipedia

I have an MSc from Surrey University in Environmental Management.

The Earth has passed a 'tipping point', as far as temperature is concerned, so the future is unknown

the only thing we know for certain, is that rikz is a tw@t, who believes any old shlt that is printed

Extinction events seem to occur about every 30 million years, which coincides with the frequency of the Solar System's passage through the orbital plane of the galaxy. The theory goes that the increased quantity of matter close to the orbital plane disrupts the Oort cloud causing increases in the numbers of comets coming into the inner Solar System and thus an increase in the risk of collisions with comets (and asteroids). The last such event took place at the end of the Eocene about 34 million years ago and is thought to be associated with a 100km-diameter crater in Siberia. The one before that was the end-Cretatceous impact 65 million years ago to which you refer.

A comet struck Jupiter in 1994 (this is far more common than comets striking the inner planets, and Jupiter's gravity protects the inner planets from incoming comets to some degree). The most dangerous object in the Solar System at the moment is Comet Swift-Tuttle. It will pass within 15 million miles of Earh in 2126 and again in 2261; it will pass within 3 million miles in 4479, with a chance in a millon of a strike; and if it strikes it will do so with 27 times the energy of the end-Cretaceous event credited with rendering the dinosaurs extinct. That's all based on current predictions of the orbit which become less and less certain the further out you look.

It's difficult to take your participation seriously when you decide a debate on whether someone has made a mistake while quoting.

You don't need to listen to me anyway like I said all the information is easily accessible.

They are all theories, opinions and predictions(plenty have been proven false).

We have such a insignificant affect on mother nature that I wouldn't even worry. It's probably not a bad thing for the world's economy that a market has been created due to global warming and it's not a bad thing that people are more aware of trying to preserve our planet as best we can but if you think for one second we have any serious say on the earth's climate then you are wrong.
