Maintain a healthy weight for you
Keeping your weight in a moderate range can protect you from conditions such asTrusted Source:

high blood pressure
high cholesterol
heart disease
stroke
type 2 diabetes
Your body mass index (BMI) and your waist circumference are two measurements that can help determine if you have a moderate weight, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)Trusted Source.

A doctor will also consider other factors such as your age, ethnicity, body composition, and health history when recommending a moderate weight range for you.

Remember, weight isn’t just about a number on the scale. Everyone is different, so it’s best to work with a doctor to determine a moderate weight for you.

Help you get to and stay at a healthy weight. Along with diet, exercise plays an important role in maintaining a healthy weight and preventing obesity. If you are at a healthy weight, you can maintain it if the calories you eat and drink are equal to the amount of energy you burn. To lose weight, you need to use more calories than you eat and drink.
Reduce your risk of heart diseases. Exercise strengthens your heart and improves your circulation. The increased blood flow raises the oxygen levels in your body. This helps lower your risk of heart diseases such as coronary artery disease and heart attack. Regular exercise can also lower high blood pressure, cholesterol, and triglyceride levels, all of which are risk factors for heart disease.
Help your body manage blood glucose (blood sugar) and insulin levels. Exercise can lower your blood glucose levels and help your insulin work better. This can reduce your risk of metabolic syndrome and type 2 diabetes. And if you already have one of these diseases, exercise can help you manage it.
Help you manage a chronic health condition. For example, regular physical activity may help reduce pain and improve function in adults with arthritis. It can also help support daily living activities for people with disabilities. This may help them be more independent.
Help you quit smoking. Exercise may make it easier to quit smoking by reducing your cravings and withdrawal symptoms. It can also help limit the weight you might gain when you stop smoking.
Improve your mental health and mood. During exercise, your body releases chemicals that can improve your mood and make you feel more relaxed. This can help you deal with stress, manage anxiety, and reduce your risk of depression.
Help keep your thinking, learning, and judgment skills sharp as you age. Exercise stimulates your body to release proteins and other chemicals that improve the structure and function of your brain.
Strengthen your bones and muscles. Regular exercise can help kids and teens build strong bones. Later in life, it can also slow the loss of bone density that comes with age. Doing muscle-strengthening activities can help you increase or maintain your muscle mass and strength. For older adults, this can mean staying independent, like being able to get in and out of a chair or bed without help.

Soil degradation is one of the challenges to sustainable tree plantations that have effects on tree growth, biodiversity, and overall ecosystem stability. The other factors affecting soil deterioration reduce soil productivity and consequently disrupt the ecosystem balance.

Deforestation: Abandoning any tree for the sake of agriculture or urbanization causes structural problems in soils and degrades organic matter. This ruins the whole purpose of a tree plantation because trees are very significant in ensuring soil stability and fertility.

Erosion: The deep topsoil, rich in nutrient content, is blown away by wind and washed away by water and difficult for plants to grow. More evidence of tree plantation is void of soil loss when trees take root-they hold the soil and prevent erosion.

Agrochemical Pollution: Excessive use of pesticides and synthetic fertilizers can reduce soil nutrient content. More importantly, they kill beneficial microorganisms. Hence, such degraded soil fetches low production from agricultural activities and drastically disrupts ecosystems, compelling the need for tree plantation in life.

Soil Compaction: Heavy machinery and overgrazing compact the soil, impeding aeration and infiltration. The resulting poor soil conditions hamper the growth of trees, derailing the purpose of tree plantations-aids in improving greenery and the environment.

Population, in human biology, the whole number of inhabitants occupying an area (such as a country or the world) and continually being modified by increases (births and immigrations) and losses (deaths and emigrations). As with any biological population, the size of a human population is limited by the supply of food, the effect of diseases, and other environmental factors. Human populations are further affected by social customs governing reproduction and by the technological developments, especially in medicine and public health, that have reduced mortality and extended the life span

The culture of the classroom can either support or create barriers to student success (Piffner,
2011).

Factors that foster attention, positive behavior, and academic and social success include
establishing positive relationships with students, adopting classroom management techniques,
and creating a physical arrangement that facilitates learning.

It is often a positive relationship with one teacher that facilitates school success for a student
with ADHD (Piffner, 2011).

When teachers connect with students and appreciate their unique skills and interests, students are more likely to strive for achievement and positively respond to classroom rules and procedures.


When using a proactive approach to classroom management, teachers support all students and
create conditions that prepare them for learning (Piffner, 2011).

Some strategies for positive management include clear directions, meaningful feedback, and opportunities for collaboration with peers. Here are some others.

Opportunities to Respond
Students with ADHD often have the most trouble attending during drill-and-practice assignments because of the repetitive nature of the tasks. Peer-mediated approaches such as those enumerated in the next screens are particularly effective for students with ADHD in such cases, because they increase students’ opportunities for engagement and active learning (Piffner, 2011).

Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life.

Types of Education. Education goes beyond what takes places within the four walls of the classroom. A child gets the education from his experiences outside the school as well as from those within on the basis of these factors. There are three main types of education, namely, Formal, Informal and Non-formal.
