How can we help the government in its initiative in fighting against global issues?

pasagot po pls:(

Answers

Answer: Water pollution, air pollution, global warming, gender inequality, deforestation and wildlife trafficking are some of the global issues.

Explanation:

The following initiatives can be taken:

1. Water pollution: For water pollution the government must take initiative to restrict the discharge of wastes from industry, sewage, and household in water. This will prevent the deterioration of water quality at global level.

2. Air pollution and global warming: The release of carbon dioxide and other polluting gases must be reduced by keeping it mandatory for all vehicles to use a catalytic filter. Also the industrial chimneys must use the catalytic filters to reduce pollution and global increase in temperature.

3. Gender inequality: Women education and empowerment must be supported so that women can compete with men and excel in all fields to reduce gender based inequalities.

4. Deforestation and wildlife trafficking: Strict laws must be imposed on forest clear cutting and ill-legal trade of animal and plant products.

What could an athlete choke on?

no inappropriate or fake answers. I need to actually know. This is based on when the Athlete is on the field.

Answers

Answer:

There are two most likely reasons why athletes choke are extreme anxiety and/or the inability to concentrate properly. Sometimes athletes get caught up in intense moments and start to feel pressure. When athletes become too anxious or stressed, their fluidity of movement and rhythm is often affected.

Explanation:

Answer: It is the ability to deal with such pressure that often separates the best from the rest. Athletes may choke when they over-analyse actions they usually perform naturally, have too strong a desire to preserve their image, and engage in poor coping strategies.

Write a letter to a FICTITIOUS friend who is addicted to TOBACCO. The letter should describe at least three different ways to quit smoking. Write at least one paragraph with all required information Presented.
ill CA u 2 dollars if it's good enough

Answers

Dear friend,

It has come to my concern that your health has increasingly deteriorated since your smoking habit has come abroad. I am writing this letter, to make sure that you can rethink your choices of this horrendous habit of yours.

Think about the risks when it comes to smoking. Lung cancer, throat cancer, blood cancer, high blood pressure, is this not enough? Ulcers and reflux, kidney disease, emphysema, do these deathly diseases really sound worth it to smoke? 480,000 deaths are caused by smoking per year in the United States of America alone, 41,000 deaths from second hand smoking. I cannot sit here wait for you to do something about it! I need you to stop smoking before it's too late.

Have you thought about your future? Cigarettes and tobacco are extremely expensive and are using up your money that you should be saving up for in the future. The average cost of a packet of cigarettes is $6.28 in the US, which means someone like you, a pack-a-day smoker, sets your savings back $188 per one month and $2,292 per year. This would mean that by ten years, you would've wasted a total of $22,920. This money could go into things that you love, other than cigarettes.

Do you really think that it is cool to smoke? Is that why you do it? Well, smoking is not cool and it is not alright. Just because your friends think smoking is cool, it isn't. Smoking levels in teens has increasingly lowered in the past years, you know why? Because they have realized that smoking isn't cool, it isn't trendy and it definitely wont get you anywhere but on the streets in life.

So really, do you still want to keep smoking? I'm only writing this to you because I care about you.

Signed,

Your friend.
