<p>The world would die unless we found a replacement for the oxygen that would be lost by the loss of every forest.</p>
<p><br></p>

<p>This is what we called deforestation.</p><p>What is deforestation?</p><p>Deforestation is the permanent removal of standing forest. It is the clearing, destroying and removal of trees  through deliberate, natural or accidental means.</p><p>Because of this, what happens is that the negative effects of climate changes are decreased. If rainforests are depleted through deforestation, carbon dioxide is allowed to escape into the atmosphere and it combines with the other gases which compose this blanket of air.</p><p>Also One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat; not only do we lose those known to us, but also those unknown, potentially an even greater loss</p><p>In addition to the loss of habitat, the lack of trees also allows a greater amount of greenhouse gases to be released into the atmosphere. Presently, the tropical rainforests of South America are responsible for 20% of Earth’s oxygen and they are disappearing at a rate of 4 hectares a decade. If these rates are not stopped and reversed, the consequences will become even more severe.The trees also help control the level of water in the atmosphere by helping to regulate the water cycle. </p><p>Also With fewer trees left, due to deforestation, there is less water in the air to be returned to the soil. In turn, this causes dryer soil and the inability to grow crops, an ironic twist when considered against the fact that 80% of deforestation comes from small-scale agriculture and cattle ranching</p>

<p>Trees are needed for life as we know it. Trees create oxygen which we breathe. Take away that and we will have issues. Trees absorb carbon dioxide and potentially harmful gasses, such as sulfur dioxide, carbon monoxide, from the air and release oxygen. Without this the gases will be in the atmosphere and the results could be catastrophic.</p>
<p>One tree supplies enough oxygen for 4 people to breath per day which is fairly impressive and didn't know that.&nbsp;</p>
<p>Trees have been a good resource as building materials for centuries and finding an alternative will take some doing. they provide a habitat for various species of birds and animals which help the eco system thrive.</p>

<p>I don't think without forest there will be any human or living thing any more on this world.</p>
<p>There are so many things to talk about like Global Warming and all but at the end I think if there will be no forest then there will be nothing at the end.</p>

<p>This is a question that invokes my passion because I am an advocate for nature, I'm an environmentalist and its always a bother to me when people live their lives destroying that which protects them. </p><p>Forests plays vital roles in our lives that a lot of people are not aware of. </p><p>First, forest helps to prevent desert encroachment. Without the forest trees, the harmful effects of UV radiations will kill plants and dry out lands such that there'd be no more arable lands. Which would mean the death of the human race. </p><p>Another thing is that forest trees helps in carbon sequestration. Without the forest trees to trap excess carbon. the amount of carbon dioxide in the atmosphere will greatly increase if the trees weren't present. Let's remember that Carbon dioxide is a green house gas, its concentration in the atmosphere could lead to global warming. What forest trees does for us is enormous in these regards. They couldn't trap carbon in the atmosphere for years and are not released till someone cuts them down an burn them. </p><p>Also, forest trees acts as water sheds. They help to collect raindrops and slows their fall to the surface of the earth, the forest floor. This greatly reduces precipitation and its resultant effect. </p><p>Forest tress act as wind break. Imagine a wind coming with a full force unhindered. It could destroy houses, farm lands and even lives. These trees helps prevent that. </p><p>These and lots more are some of the functions that these trees does for us. What I've written here are only about treesa and their effect on humans. There are other functions, apart from trees, that forests provides. </p><p>We cannot simply live without these works of creation. Lets do all to ensure their sustainability. </p>

<p>Forest help in balancing the oxygen and carbon dioxide released in the atmosphere.  The co2 released by man is utilized by plants while man utilizes the O2 released by plants. When this balance is distorted by removing forest, there'll be serious problems for man and other living organisms that depend on oxygen for survival.  Though man knows the usefulness of forest and there's no way the earth will be  without forest because man will never allow such to happen </p>

<p>We know that if you cut forests on land, the main problems will be the global warming t, the lack of natural air purifiers, and the smok and co2 contamination will increase.</p>

<p>I comment from my own experience.</p>
<p>I have varied farms in the tropics, where there are &nbsp;jungle forests.</p>
<p><br></p>
<p>There were parts of my farm where there were a lot of trees, and in order to work I had to cut several. (60hect)</p>
<p>Before doing it the terrain was humid, almost the sunlight did not touch the ground, it was sometimes dark inside the forest.</p>
<p><br></p>
<p>When cutting the forest, the temperature of the sun increased, it was almost impossible to be there at noon. Each time it gets hotter and the soil moisture disappears.</p>
<p><br></p>
<p>Sometimes the human being to earn a few dollars seems to destroy nature.</p>
<p>My farm is small but imagine the amount of trees that set cut down around the world.</p>
<p><br></p>
<p>The lands that were fertile &nbsp;will no longer be soon.</p>
<p>One of the problems is the excess of population and the indiscriminate printing of dollars.</p>
<p>If there were fewer people in the world, fewer resources would be demanded.</p>
<p>&nbsp;<br>
In conclusion, the world would be hotter and drier and polluted, but the human being would evolve.&nbsp;</p>

<p>Many people think that all the oxygen on our planet is produced by plants but all this is a myth.</p>
<p>It's very common to think that most of the oxygen we breathe comes from trees and jungles, however, terrestrial ecosystems produce like a 28% in the world. According to various studies, at least 70% is produced by marines plants.</p>
<p>The ocean produces oxygen through the plants phytoplankton, seaweed, algae and plankton that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process that converts carbon dioxide and sunlight into sugar that the body use to obtain energy.</p>
<p>One type of phytoplankton, the Prochlorococcus, release countless tons of oxygen into the atmosphere and has achieved fame as the most abundant photosynthetic organism on the planet. It's stimated that Prochlorococcus provides oxygen for one out of every five breaths we take.</p>
<p>However, some scientists believe that phytoplankton levels have been reduced by 40% since 1950 due to the warming of the ocean. The nutrients from these organism reach the surface as a result of water currents that circulate cold water and nutrients from the deeper water to warmer surface water.</p>
<p>As the ocean heat up, there is less circulation of hot and cold water through the global conveyor belt, so there are fewer nutrients for phytoplankton. 70% is a really good part of the total exigen produced, so the decrease of the phytoplankton affects the ecosystem to a greater extent.</p>
<p>In conclusion, even though the destruction of all the forests would mean a reduction of oxygen in 28% wouldn't end life on the planet, this would be a serious blow to the balance of nature, basing us on the theory of the butterfly effect, which says that flutter of a butterfly, however small, can generate a storm on the other side od the world.</p>
