This study demonstrated a relationship between care given according to Watson's Caring model and increased quality of life of the patients with hypertension. Further, in those patients for whom the caring model was practised, there was a relationship between the Caring model and a decrease in patient's blood pressure.
The greenhouse effect is a warming of Earthâs surface and the air above it. It is caused by gases in the air that trap energy from the sun. These heat-trapping gases are called greenhouse gases. The most common greenhouse gases are water vapor, carbon dioxide, and methane.
Causes of Greenhouse Effect. Forests help in maintaining the balance of nature by absorbing the excess carbon dioxide present in the atmosphere. Cutting down of trees, thus, leads to an increase in the carbon dioxide level in the atmosphere, eventually enhancing the greenhouse effect.
