How to answer a causes-and-solutions essay

A full example — intro, two body paragraphs, and a conclusion

In numerous countries, people are becoming heavier while their levels of fitness steadily decline. This essay will examine the two most significant causes behind this trend — sedentary lifestyles and poor diet — before suggesting two realistic measures governments could take to address it, from fiscal policy to investment in public infrastructure.

The first cause is the sedentary nature of modern life. Many jobs now involve sitting at a desk for hours, commuting by car rather than walking or cycling, and relaxing in front of a screen rather than being physically active. The second is diet: cheap, heavily processed food loaded with sugar and fat has become far more convenient than preparing fresh meals, particularly for busy families with little time to cook, so many people now consume more calories than their inactive lifestyles actually require.

One effective measure is fiscal policy that targets unhealthy products directly. When the United Kingdom introduced its Soft Drinks Industry Levy in 2018, taxing manufacturers according to sugar content, most major producers reformulated their recipes rather than pay the charge, meaning many popular drinks now contain noticeably less sugar than before. A second measure is investment in active infrastructure — building cycling lanes, safe pedestrian routes, and affordable public sports facilities — so that physical activity becomes the convenient choice rather than an effort people have to make time for, particularly in cities where a car is currently the easiest option.

In conclusion, rising obesity and declining fitness stem mainly from sedentary routines and poor diet, but neither is inevitable. Combining fiscal measures like a sugar tax with sustained investment in infrastructure that makes activity easy gives governments a realistic, evidence-based path toward a healthier population.
