67. Every U.S. dollar spent on foreign aid buys five gallons of clean water to distribute to people in need. Out of every five gallons of clean water intended for people in need, two gallons are lost due to environmental factors, transportation problems and conflict. If the United States spends $12 million on foreign aid in one year, how much of that money would actually make it to the people in need if spent on water?

68. If the United States spends $1 billion a year on foreign aid and, of that money, 55% contributes to human rights improvements, 25% contributes to HIV/AIDS treatment and prevention, and 5% contributes to infrastructure improvements, how much money of the foreign aid budget is left to spend on food and water?

69. The World Wildlife Foundation recently reports that the number of monarch butterflies overwintering in Mexico has declined drastically. Although extreme drought conditions have dried up nectar plants monarch butterflies rely on for food. The destruction of their overwintering grounds also poses a considerate threat.

When monarch butterflies arrive in Mexico from Canada and the United States, they converge on oyamel fir trees. The trees provide shelter to monarch butterflies they are also essential to the communities that surround the forests. In the past, residents used the wood for cooking and heating, but recently, they have began to sell it in order to support their livelihoods. As a result of logging oyamel fir trees, the habitat of the monarch butterfly population has shrunk.

In 2008, scientists used satellite imagery to illustrate the degradation of oyamel fir forests. Officials from Canada, Mexico and the United States met to quickly develop a monarch butterfly conservation plan. A key feature of the plan focused on protecting the monarch butterflies’ habitat. Mexico agreed to enforce a ban on logging within the Monarch Biosphere Bio Reserve.

Despite various conversation efforts, including paying landowners for logging rights, the monarch butterfly population continues to decline. There was a 28 percent reduction in numbers of butterflies overwintering in Mexico. If further efforts are not made, some scientist predict the total collapse of the ecosystem that supports monarch butterflies in Mexico.

At what time of year are butterflies in Canada?
