A tornado requires patterns of both cold and warm air in the same region in order to form. The most likely time for this to occur is during warm or hot weather when a thunderstorm is approaching. The tornado is created when warm, moist air rises from the ground and comes into contact with a mass of colder air at the bottom of a thundercloud. The rising air pushes against the colder air, and the rotation of the earth causes the air to spin, (18) _______.

As mentioned, tornadoes generally, but not always, develop in conjunction with a thunderstorm. Thunderstorms that result in tornadoes are referred to as supercells. (19) ______, especially when other conditions, such as a cold front or low-level converging winds, are also present. (20) ______, these clouds get caught up in the tornado’s swirling wind, which creates the menacing funnel that most people associate with danger and destruction of property.
(21) ______. The first stage occurs just before the onset of a thunderstorm, when the wind changes direction and increases its speed. As the wind moves faster and higher in altitude, it begins an invisible horizontal spin. Once the thunderstorm starts, rising air inside the storm causes the spinning wind to become vertical, or to shift from side to side to an up-and-down position. The thunderstorm then surrounds this area of rotating air, which can vary in length. Clouds that have formed in the lower part of the thunderstorm (22) ______. Shortly after the completion of the previous step, the tornado develops.

In 2023, the U.S. Surgeon General declared loneliness an epidemic, stating that its consequences extend far beyond “just a bad feeling”. While loneliness is typically recognized as an unpleasant emotional response to perceived isolation, it can also have impacts on cognitive, physical, and mental health.
The terms “loneliness” and “social isolation” are often used interchangeably, but they differ in some fundamental ways. Loneliness refers to the subjective feeling of being alone or lacking meaningful social connections. Social isolation, however, describes the objective lack of social contact.
Loneliness is also not the same as solitude. Some people may enjoy time alone, whether it’s for brief or extended periods of time, and therefore don’t suffer the same negative health outcomes as those who feel lonely. Perceived loneliness—the degree to which someone feels that their social needs are not being met—is influenced by various social determinants of health, including socioeconomic status, access to healthcare, and environmental factors.
The U.S. and Canada have experienced a substantial rise in loneliness in recent years. In the U.S., rates of loneliness are notably high among young adults, people with lower incomes, and racial and ethnic minorities. These findings are consistent in Canada, with approximately two-thirds of 18 to 54-year-olds reporting that they feel a lack of belonging and 76% of unemployed people feeling cut off from their communities.
The effects of social isolation can be significant. Research links chronic loneliness to an increased risk of depression, anxiety, and cognitive decline, including dementia. Loneliness can also trigger inflammatory responses in the body, impacting brain function and potentially accelerating age-related cognitive decline.
Healthcare providers play a vital role in addressing this public health crisis. By acknowledging the profound impact of social isolation—and conversely, social connection—on patient outcomes, they can advocate for lifestyle changes that promote social connectedness and reduce feelings of loneliness.

Being food-secure means having consistent access to enough food, even during natural disasters and economic crises. This can be achieved either through domestic food production or by importing food from abroad. For economic reasons, many in developing countries deal with a lack of food security every day, while for others, it only becomes a concern when disasters such as extreme weather or economic crises strike. Now, climate change means that natural disasters are occurring more often, and thanks to globalization, a problem in one country can often affect people worldwide.
Seemingly “natural” disasters leave countries like Bangladesh highly unstable in terms of food security. In fact, climate change has left Bangladesh at increased risk of flooding as cyclones become more common and sea levels rise. Located at the convergence of three major rivers, most of Bangladesh is less than five meters above sea level. In 2007, after prolonged heavy rain, an estimated 26,500 farm animals were lost to floods, and fish farms—a major source of food—were also affected as fish escaped back to sea. Above all, Bangladesh relies on rice, and the 2007 floods destroyed 2.2 million tons of the crop. [I] As a result, prices rose sharply. An estimated ten million people were left without access to enough food. In response, the United Nations World Food Programme (WFP) spent $51 million feeding 2.3 million people for six months.
Another food crisis in 2008 was more obviously global. Droughts in Russia, Ukraine, and Australia led to major crop failures. [II] These countries are major exporters of wheat, and without their input, a world shortage occurred. At the same time, oil prices were high due to continued demand from developed countries and increased demand from the developing world. Oil is required for intensive, mechanical agriculture, so producing crops became more expensive, and farmers passed this cost on to consumers.
[III] As an alternative to oil, the US began using more of its crops to produce biofuels (fuels made from plants or animals). This seemed like a sustainable solution, but it left even fewer crops for food, creating more scarcity. Finally, in some developing countries, as populations became larger and wealthier, demand for food grew. [IV] So just when crops were needed most, they were in short supply and were expensive to produce; at the peak of the crisis, the prices of wheat and rice rose by almost one hundred percent.
