Because the trees take our carbon dioxide and gives us oxygen in return. It will also low the rate of oxygen provided by trees leading to may be increase in the global warming rate, and also production of heat and suffocation in crowded rooms
Trees and plants, in general, produce energy for growth using a process known as photosynthesis. Using light, water and carbon dioxide, a plant produces energy in the form of sugar and releases oxygen into the air. Forests cover approximately 30 percent of the land on earth and sustain nearly 80 percent of the world's terrestrial organisms. It is estimated that one acre of trees in urban forests can produce enough oxygen for eight people and remove 188 pounds of carbon dioxide from the air.
Oxygen comprises only about 21 percent of air's chemical component. Yet, it is extremely important to life on earth. Living organisms, from single-celled animals to humans, use oxygen to produce the energy required to sustain them. Since trees are larger plants, their production of oxygen is significant. It is estimated that tropical rainforests, produce 40 percent of the earth's oxygen even though they cover only about 6 percent of the land. Rainforests in the Amazon have declined by 17 percent in the last 50 years as a result of deforestation.
An acid rain is a type of rain or precipitation that has a high level of hydrogen ions resulting in low pH. It can prevent growth of seedlings because it hinders the cell division of plants. Since animals consume plants, they can establish new dietary habits or migrate to areas that have a healthier environment.
The Kozak sequence is a sequence which occurs on eukaryotic mRNA and has the consensus. It also plays a major role in the initiation of the translation process
In an oceanic environment, the photic zone is the zone where light can be received, it's usually from 0 to 200 m deep, but this depth can be modified by the turbidity of the water. The aphotic zone is the zone where no light is received, it goes from 200 to the bottom of the sea.
