Answer:

1- Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.

2- Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.

3- Humans affect erosion rates in a number of ways across the globe. ... Human activities such as repeatedly walking or biking the same trails or areas can also contribute to erosion slowly over time. Forest fires also contribute to soil erosion, as vegetation previously holding the soil in place is often destroyed

4 - The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

5 - You can reduce soil erosion by:

Maintaining a healthy, perennial plant cover.

Mulching.

Planting a cover crop – such as winter rye in vegetable gardens. ...

Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

You have bandaged a victim's lacerated elbow. Blood is still soaking through the dressing and bandage. What should you do?
morpeh [17]

Answer: The correct answer to the question is option D

APPLY ADDITIONAL DRESSINGS AND BANDAGES,KEEP APPLYING PRESSURE,LIFT ARM ABOVE THE HEART.

Explanation: To answer the question effectively,let's look at the options critically and the effects it will have on a bandaged lacerated elbow that still has blood soaking through the dressing and bandage.

A) Remove the dressing and bandage and start over again with a tighter bandage.

This is a big NO when it comes to wound dressing and care because removing the dressing and bandage will impair the blood clots that must have formed in the lacerated site,this blood clots helps to control the bleeding so when the bandage and dressing is removed,the blood clot will be distorted which will make the wound to start bleeding again.

B) Apply a tourniquet around the wrist.

Application of tourniquet is the last resort in control of bleeding,it is only employed when other measures to control the bleeding has been applied but proved abortive so application of tourniquet is not the right and appropriate measure to be taken at this time.

C) There is nothing else you can do.

This can be termed an act of negligence and its not expected of a healthcare provider,leaving the victims lacerated elbow to be soaking of blood through the dressing and bandage will cause the victim to loose much blood and this might result to shock.(hypovolemic shock)

D) APPLY ADDITIONAL DRESSINGS AND BANDAGES,KEEP APPLYING PRESSURE,LIFT ARM ABOVE THE HEART.

This is the right and most appropriate measure to be taken in the case of a laceration or wound that has blood still soaking through the wound and dressing. The goal is to apply more pressure inorder to maintain homeostasis (control the bleeding).

The arm should also be lifted above the heart to decrease the flow of blood,improve venous return and prevent obstruction of a blood vessel as a result of a blood clot. (thromboembolism).

After the measures has been ensured,the victim should be closely monitored for any skin discoloration (blueish discoloration especially of the extremities),signs indicative of shock,faster breathing or slower breathing and restlessness.
