The declining environment has made several alterations to many living species and ecosystems affecting a global spectrum of people. We are forced into a position to either unite as a team or sit back and watch our environment slowly decompose. These two options are resulting from worldwide environmental problems that are and have been arising over the years and have made a significant impact on all species of organisms. Consequently there are numerous crises that billions of people are facing on a global scale. I will cover a few universal issues that have come about such as not having accessible clean water, the global warming theory and its effect on the environment, as well as issues threatening forests. Many different species belonging to ecosystems are also affected by multiple factors. The environment can be such a beautiful place when special care is maintained. However, when the environment lacks attention, worldwide problems appear.
As far back as we can recall, water has been around for several decades providing living species with a sustainable life. Over half of the human body is composed of water and this nutrient is accountable for clothes, food, and electronics, in addition to keeping us healthy. Water is somewhat of a theoretical idea to most people but can have an alarming reality check for others. The obtainable amount of water has been rather constant over time through continual recycling; however the population has intensified and has made the competition for fresh drinking water difficult. Providing statistics of the problem may put this crisis into perspective and support my claim. In regards to the National Geographic, "According to the United Nations, water use has grown at more than twice the rate of population increase in the last century. By 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change"(Freshwater,2010). Many less and underdeveloped countries face the water crisis on a daily basis such as India. Many cities in India encounter environmental problems due to the vast amount of population growth. Most of the days spent by women and young girls are waiting in line to get their portion of water to supply for their family. Most of the women can't have a job and the young girls are not able to go to school. I feel the demand for this global trend is to manage, utilize, and allocate water more efficiently in order to combat or just reduce this crisis and keep ourselves and the environment healthy.
In addition to the worldwide water disaster, the world is becoming united by watching many forests and trees become damaged. Deforestation is directly correlated with a greenhouse gas we are all familiar with which is carbon dioxide. The main problem of deforestation stems from this gas when trees are cut down and forests are destroyed. From my understanding, carbon dioxide is absorbed through trees, oceans, plants, and grass and when you take away the forests there will be an increase of atmospheric CO2. "Over the past 150 years, deforestation has contributed an estimated 30 percent of the atmospheric build-up of CO2. It is also a significant driving force behind the loss of genes, species, and critical ecosystem services. However, in the international policy arena, biodiversity loss and climate change have often moved in entirely unconnected domains"(Shah,2010). My perspective on this issue is if you take away our forests, the unabsorbed CO2 is going to be in the atmosphere and in return, there will be more CO2 emissions in the air and possibly increase global warming.
A theory that has been discussed diversely over the past years has been the effects of climate change and global warming. Some people say this theory is a fact while others think it is a myth. I however think this is a problem we are facing now and need to be proactive towards the issue. For millions of years the earth's climate has fluctuated from warmer and cooler temperatures but in the latest years our climate has rapidly increased in temperature. But the main question is what is causing the climate to change so quickly? It could be the rapid population growth, increase production of natural resources emitting carbon dioxide, or in combination with the greenhouse effect of intensified use of natural occurring gases. "As the mercury and greenhouse gas levels rise, the climate can change in unexpected ways. In addition to sea levels rising, weather can become more extreme. This means more intense major storms, more rain followed by longer and drier droughts, which can be a challenge for growing crops, changes in the ranges in which plants and animals can live, and loss of water supplies that have historically come from glaciers"(What is Global Warming,2010). I can say not everyone agrees with my position due to the controversial nature of this topic and someone from an opposing position might say that there is no evidence that CO2 emissions raise temperatures because it has never done so in the past. Some could say that global temperature is constantly changing but climate is not driven by the amount of carbon dioxide in the atmosphere. On the other hand, the atmospheric temperature has risen quickly and there is supporting evidence that global warming does occur and I feel we need to unite together to decrease the effects of global warming.
Many individuals on a global dimension have been faced with the option of unity and cooperation or disunity and a common tragedy on the other. I have mentioned there are multiple degrees of crises that have a significant effect all around the world. What may be an intense crisis to one country might be a taken for granted subject in another country. Various species contribute to an ecosystem in different ways on multiple levels. However, all species need other sources of living things and vice versa to maintain a sustainable environment universally.
