Did you know that teenagers should spend at least 60 minutes daily participating in physical activities? In today's world where 4-6 hours of screen time is very common, less than 30% of teenagers spend the recommended time exercising. Besides a good diet, regular physical activities are an essential part of keeping teenagers healthy as they can improve teens' physical and mental health. Exercising helps maintain your fitness and reduces the risk of many health conditions such as heart disease, obesity, and diabetes... If you have trouble falling asleep, daily physical activities can benefit your sleeping pattern. Starting exercising in their teenage years, many people successfully established the habit of working out, which is key to a healthy lifestyle. Types of exercises suitable for teens include running, swimming, cycling and playing sports... When short of time, you don't have to spend an hour doing intense physical activities. Instead, 30 minutes of light exercises like walking, climbing stairs, and doing push-ups and sit-ups is acceptable. If you have a hard time committing to a regular schedule, try choosing activities that you enjoy or asking your parents and friends to join in.

Shifting from fossil fuels to renewable energy is crucial to the fight against climate change and the build of a more sustainable future. So what are the benefits? Are there any disadvantages?

Renewable energy won't run out. The process of turning natural resources such as the sun, wind, and water flow into energy also releases fewer pollutants. Cutting down greenhouse gas emissions will lead to a less polluted and cleaner environment.

However, renewable energy technologies are very expensive and using them requires significant investment. These energy sources can also be unreliable as weather conditions can affect the energy supply. Storing energy is one of the solutions to this problem. Though, the cost of energy storage of high capacity is still too high.

In conclusion, renewable energy is not the perfect solution to climate change. Although there are some drawbacks, these disadvantages can be addressed as new technologies develop.
