What else is out there?




Learning about the various biomes exposes the variation of resources on earth. In a larger perspective, it is easier to portray our community as a small part of the rest of the ecosystem. It is still very important to have the same consideration for all existence on all other biomes because they all contribute to our ability to live.

If you look at forests and the idea of importance in climate discussed in class. A prevailing climate is the most important factor in determination of a biome. It is interesting to think about the size and capacity that forests take up. If drastic changes were to occur to the many forests in our ecosystems, it is scary to think of the consequences we will suffer. Forests were used from the reindustrialize for slash and burn methods which have left many depletions of carbon dioxide and soil erosion. Along with many technological techniques, many new practices has decrease populations in biomes such as keystone species.

It is important to keep the global diversity because at the end each system within the ecosystem depend on each other. Another biome which should really be appreciate is the water biomes. Water is a main source of our life and allows us to maintain crop production. Without water, many species would not be able to sustain their lives.

However, issues such as pollution and runoff lead to the great depletion of water. Practices that are used in crop production such as fertilizer being run off in fresh water and restrict proper water production for the hydraulic cycle and for plant growth. Another major factor of water is the over fishing and population which corrupt the ecological systems in the oceans. This is represented in the movie Affluenza which was seen in lecture on the twenty-first of September. This movie emphasized on the issue of collapses and changes in the ocean which are caused by the consequences that people have caused. Some of the most productive fishing sites have diminished because the impacts have become severe. Fisherman make a living on what they catch, however in order to increase their income they invest in larger boats and more advanced technologies which deplete the marine biome.

People need to be aware what is occurring in the water because we greatly rely on the water species even if it is not for food consumption. The estuaries are coastal bodies of water which are partly surrounded by land and have access to open ocean and the fresh water. Many industrial pollutants are dumped upstream the estuaries which then lead to defects for many lives in the marine because the estuaries merge the fresh water rivers with the oceans. It may be difficult to sustain stability in the ecosystems because of resource depletion. Also many of the biomes have such different species that levels of adaptations vary greatly.
