Environmental Hazards: Cultural‚ Biological‚ Physical and Chemical An entirely different perspective is brought into focus as we consider some of the environmental hazards that accompany industrial growth and intensive agriculture. Some of the most dangerous hazards in this world are the outcome of purely voluntary behavior --- in particular‚ smoking tobacco and engaging in risky sexual activity. We will look at four classes of environmental hazards: Cultural‚ Biological‚ Physical and Chemical

Situation: Two patients in their 70s present to the office at different times today‚ each with documented heart failure: one diastolic and the other systolic‚ and both are hypertensive. First‚ discuss the difference between systolic and diastolic heart failure‚ providing appropriate pathophysiology. ACEI/ARBs are the only medications prescribed for CHF that have been found to prolong life and improve the quality of that life. EXPLAIN the mechanism of action of ACEI/ARBs and how they affect morbidity

There are many incentives to move away from vivo testing. One of the main motivations to use alternative methods is ethical: toxicity tests in all fields are associated with high levels of suffering (Burden‚ Sewell‚ and Chapman 1-8). Not only are there ethical drives‚ but there are also scientific drives to ultimately eliminate animal testing (Burden‚ Sewell‚ and Chapman 1-8). One scientific drive is the question that must be answered: is it acceptable for a human being to be exposed to it‚ not just

properly organized and motivated‚ we can dramatically reduce the effects of global warming. There are several ways that people can help in protecting our environment. We can do this by changing our lifestyle by saving our water resources‚ reducing toxicity by not using those products that contain chlorofluorocarbons‚ and protecting our air and conserving our energy resources‚ all of these are very helpful if we were to create a better world for the people of this planet.
