The Antarctic, one of the world’s last great wildernesses and home to animals such as whales, penguins and leopard seals, is being threatened by the plight of an animal just a few centimetres long, according to scientists.

Krill, which grow to about six centimeters, or two inches, occurs in vast schools and is the major source of food for whales, seals, penguins and sea birds. Without it, scientists say, the ecosystem in and around Antarctica could collapse.

Answer. Brief answer: In a food chain, squid and fish eat krill. If the population of squid and fish decreases, the krill population will rise dramatically because less krill will be eaten.

Krill populations have declined by 80 percent since the 1970s. Global warming has been blamed for part of that decrease because the ice that is home to the algae and plankton they feed on is receding. Campaigners say recent developments in fishing technology are worsening the problem.

To better protect krill and other Antarctic wildlife and their habitat, Pew and other conservation groups have called for wildlife observers on all krill fishing vessels, dedicated funding for ongoing monitoring of Antarctic krill predators and more localized, focused management of krill fishing areas to better protect …

The most common side effects of krill oil include stomach upset, decreased appetite, heartburn, fishy burps, bloating, diarrhea, and nausea.

In addition to following a heart-healthy diet, some types of drinks may also be helpful when it comes to lowering your blood pressure. According to research, several types of fruit and vegetable juices, as well as skim milk and green tea, may help to control your blood pressure, without any side effects.

Water drinking also acutely raises blood pressure in older normal subjects. The pressor effect of oral water is an important yet unrecognized confounding factor in clinical studies of pressor agents and antihypertensive medications.

Always try to use the bathroom before getting a reading. Poor support for your feet or back while seated can raise your blood pressure reading by 6 to 10 points. You should sit in a chair with your back supported and feet flat on the floor or a footstool.

Sugary drinks that may contain caffeine or high fructose corn syrup can include sodas and fruit juices.

• Alcohol. Drinking too much alcohol can raise a person’s blood pressure, according to the American Heart Association.
• Processed and prepackaged foods.
• Caffeine.

Stress-reducing activities can lower your blood pressure

1. Simplify your schedule. If you always feel rushed, take a few minutes to review your calendar and to-do lists.
2. Breathe to relax. Taking deep and slow breaths can help you relax.
3. Exercise.
4. Try yoga and meditation.
5. Get plenty of sleep.
6. Shift your perspective.

The first measurement should be in the morning before eating or taking any medications, and the second in the evening. Each time you measure, take two or three readings to make sure your results are accurate. Your doctor might recommend taking your blood pressure at the same times each day.

If your blood pressure is extremely high, there may be certain symptoms to look out for, including:

• Severe headaches.
• Nosebleed.
• Fatigue or confusion.
• Vision problems.
• Chest pain.
• Difficulty breathing.
• Irregular heartbeat.
• Blood in the urine.

Slow, deep breathing activates the parasympathetic nervous system which decreases the heart rate and dilates blood vessels, reducing your overall blood pressure. As your breathing becomes slower, your brain associates it with a state of relaxation, which causes your body to slow down other functions like digestion.
