What is renal failure?</h3>
- When your kidneys are suddenly unable to filter waste from your blood, you experience acute renal failure. 
- Dangerous levels of wastes may build up when your kidneys lose their filtering capacity, and your blood's chemical composition may become out of balance. 
- Acute kidney failure, which is often referred to as acute renal failure or acute kidney damage, occurs suddenly, typically within a few days. 
- The majority of cases of acute renal failure occur in patients who are already hospitalized, particularly in severely ill patients who require intensive care. Acute renal failure is serious and needs aggressive care. Acute renal failure, however, might be curable.

Ave you ever wondered why one area of the world is a desert, another a grassland, and another a rainforest? Why are there different forests and deserts, and why are there different types of life in each area? The answer is climate. 
<span>Climate is the characteristic condition of the atmosphere near the earth's surface at a certain place on earth. It is the long-term weather of that area (at least 30 years). This includes the region's general pattern of weather conditions, seasons and weather extremes like hurricanes, droughts, or rainy periods. Two of the most important factors determining an area's climate are air temperature and precipitation. </span>
