The truth is the earth and all life in it could be in danger soon and it wouldn't be because some meteor came into earths orbit and slammed into the earth and caused our extinction nor will the sun burn out nor we fight wars of nuclear and biological warfare. The things we are doing on a day to day is hurting the climate as we know it.
Some of my friends have compared holidays they've taken in cities in comparison to those in the villages and towns closer to nature. Cities cut down trees, soo many trees to create estates where we can leave and burn more energy everyday.
There was once a film i watched cant remember which but what got me sucked and glued till today is the message it rang "HUMANS ARE THE VIRUS OF THE EARTH". No offence to people who may take that statement to heart but there is alot of truth in it.
Humans have not learnt to integrate with the earth, the red Indians of old were good examples of cultures that tried to integrate by realizing the flow of spirits in all living animals. This kind of awareness is what is needed in our present day approach to the Ecosystem.
The ecosystem is dying and dont let any statistics fool you, animals are being slaughtered faster than animals can grow from birth to maturity, fishes same. All these have brought about a trend in IMPROVED crop and animal research. These improved varieties have been able to feed us and reduce the time it tatkes for us to see food to eat.
Ice caps are melting due to the heat generated from the earth in the last century, this heat is generated from hydrocarbon fuels from coal, fuels, diesels and other harmful gases from mined hydrocarbons. The heat from these energies are harmful in such a way that they emit substances which when after burnt are non bio-degradable in the atmosphere so it goes into the atmosphere and clogs the atmosphere there, thereby displacing the natural envelop of ozone that has accumulated for millions or even billions of years which protects us from the direct rays of light from the sun that contain solar radiation in various spectrum of light.
Animals in their natural habitat are forced out or taken into captivity after their habitats have been converted to human towns which like us drives them mad and more violent than if you had left them in their original state.
I guess what i'm trying to say is.
