<span>1. </span><span>Two ways that man can reduce the global
warming is by reducing carbon dioxide (a greenhouse gas) emissions. One way is
by planting more trees. Forests are reservoirs for carbon since their remove
carbon dioxide from the atmosphere in the process of photosynthesis. Second is
by reducing the use of fossil fuels to produce energy. Fossil fuels are the biggest emitter
of carbon dioxide in their combustion</span>
<span>2. </span>Greenhouse<span> gases permit infrared rays from the sun
to pass through them but do not allow heat to escape into the atmosphere. When infrared hits the earth's surface
it turns to the heat wave that has much longer wavelengths. This causes the earth’s atmosphere to retain more heat hence
increased global temperatures.</span>
<span>3. </span><span>When greenhouse gases especially carbon dioxide are reduced in the
atmosphere, the earth is able to radiate more sunlight back into space due to the reduced greenhouse effect. This
enables the global temperatures to remain low. At the poles where temperatures are cold remains
even colder hence the waters in these regions turn to glaciers. The ice continents increase in size and hence a big characteristic
of ice ages. </span>
<span>4. </span><span>Humans are not responsible for global warming even though they contribute but in minimal proportions
as compared to the natural process. This is because
it is estimated that termites produce even more carbon dioxide than humans. Ice
ages and global warming are therefore natural
cycles governed by the sun. However,
human activity aggravates global warming. </span>
The steps of fracture repair include:
- Hematoma formation.
- Fibrocartilage Callus Formation.
- Bony Callus Formation.
- Bone remodeling.
<h3>What is a fracture?</h3>
A fracture is a complete or partial break in a bone. The causes of bone fractures include trauma, overuse, and diseases that weaken bones.
In this case, Kyndall was lucky because the fracture occurred about 3 inches below the epiphyseal plate as this means the fracture does not break through the bone at the growth plate.
An improperly treated growth plate fracture could result in a fractured bone.
Lastly, the type of fracture is a nondisplaced fracture is one in which the bone cracks or breaks but retains its proper alignment.

Answer:
Is the benefit worth the cost?
Explanation:
Environmental policies application has to lead to some economic cost.
When coming up with this policies, the effect that this policies shall have towards environmental protection shall be considered.
The cost and economic effect that this policies shall cause should also be looked at.
If a policy causes insignificant change towards environmental protection and at the same time the costs are too high, then the policy should be dropped.
If a policy has got significant impact and costs less, the it should be taken.
