Time for change

The issue with stopping or reducing global warming is about risk and managing risk: Science still does not know the exact mechanism by which smoking and its associated chemicals causes cancer. What we do know is that smoking is the biggest risk factor in developing lung cancer. The more you smoke, the more your risk of getting lung cancer. Not everyone who smokes gets lung cancer, and not everyone who gets lung cancer has smoked.

What is thermosolar power, or "desert energy"? Thermosolar energy means generating electricity from the heat of the sun, and not, as photovoltaic panels do, from sunlight. Since a large quantity of solar heat is required, evidently this must be done in the desert. A short introduction in this promising technology to produce electricity from a renewable source:

A carbon footprint is defined as:

The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).

There are two major effects of global warming:

• Increase of temperature on the earth by about 3° to 5° C (34° to 41° Fahrenheit) by the year 2100.

• Rise of sea levels by at least 25 meters (82 feet) by the year 2100.
