Immediately in front of the Main Building and facing it, is a copper statue of Christ with arms upraised with the legend 'Venite Ad Me Omnes'. Next to the Main Building is the Basilica of the Sacred Heart. Immediately behind the basilica is the Grotto, a Marian place of prayer and reflection. It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858. At the end of the main drive (and in a direct line that connects through 3 statues and the Gold Dome), is a simple, modern stone statue of Mary.

Problem: Context: Divorce is bad for environment US researchers raised a new theory on Monday: divorce is bad for the environment. The global trend toward higher divorce rates has created more households with fewet People,scientists at Michigan State University reported in the Proceedings of the National Academy of Sciences. More households means more houses,fuel and water are Heeded for them,the researchers wrote."Globally,the number of households is increasing much faster than the number of people,"said co-author "Jack" Liu in a telephone interview. "Even in regions with declining population, we see _ increase in the number of households. Divorce is the main reason for reducing the number of people in a household," he said. The average divorced person's household is about 40 to 50 percent smaller than the average married person's household, Liu said. But whether there are three or six people in a house ,the amount of fuel needed to heat them is about the same. In the prefix = st1 /United States, divorced households used 73 billion kilowatt--hours of electricity and 2.850 trillion litres of water in 2005 that could have been saved if households had stayed the same size as when they were married.

The number of rooms per person in divorced households was 33 percent to 95 percent greater than in married households. "If you really want to get divorced, maybe you can remarry with somebody else, or live together with somebody else you like", Liu said.
