how difficult its to save our eart from from on big disease global warming?

First off, that's a pretty controversial topic. Personally, I do not believe in Global Warming, and the fact that 'man is ruining our earth'. The earth has cycles of warming and cooling periods, and man's pollution is not causing 'global warming'.

I concur with a few of the previous posters. It's a natural phenomenon, and humans do not influence it. Global warming is actually beneficial to the environment, why would you want to stop it?

Even if global warming IS a natural phenomenon, What can it hurt to make goals to reduce energy and work toward something?

Global warming is a natural phenomenon that occurs in cycles and it can't be stopped. The global warming alarmists want to convince you that manmade CO2 is poisoning our environment and contributing to global warming. It's a lie! For one thing, man accounts for only about 3% of all CO2. Nature creates the rest. The second thing is that there are many factors that contribute to global warming far more than manmade CO2 - if it even contributes at all - and these factors are totally beyond our ability to control. Factors such as volcanic eruptions, the oceans, and solar activity are a few of the factors that scientists have documented as having major roles in influencing the changes in climate. The global warming movement is nothing more than a scam aimed at giving more money and power to those who are pushing it - politicians, environmentalists, celebrities, etc. - all at the cost of fewer freedoms and money for you and me.

Its not hard at all to save earth from global warming. Both the Businesses and individuals, if take part from thier side, a lot can be done. Factories can start using recycled products that they use in manufacturing also in thier offices, etc. At the same time, they should recycle the wasts as much possible. Vendors often pack up thier product in lot of packaging layers that is not necessary at all. Thse heavy packaging should not be used. Individual people can play similar roles and there are lot of guides, method published already online, in book for people telling how to make environment green.
