Effects of Consumption and Production Patterns on Climate Change

Let Us Study

Weather tells the environmental condition in a specific place. It can be rainy, sunny, windy or snowy while Climate describes the weather conditions expected in a particular place in a specific time of the year. Climate change refers to the significant change in the average conditions of temperature and rainfall in a particular region over a long period of time. An amazing scientific accord highlighted that global climate change is due primarily to the human use of fossil fuels that releases dioxide and alternative greenhouse gases into the air. The gases trap heat inside the atmosphere, which may have a variety of effects on ecosystems. the results square measure the following; (a) rising ocean levels, (b) severe weather events, and (d) droughts that render landscapes additional vulnerable to wildfires. It is already happening in our planet even before it is inhabited by humans but scientists have observed that changes nowadays are too unusual, making them more alarmed. For over 20,000 years, much of the European regions were covered with glaciers. Today, climate all over Europe is quite warmer compared to its condition 20,000 years ago. Globally, warming temperatures and changes in precipitation are observed. The results of all these climatic changes include: A. sea levels rising, B. fewer mountain glaciers, C. faster melting of the ice in Greenland, Antarctica and the Arctic, and D. changes in flower and plant blooming times. A lot of factors are contributory to the global climate change but scientists have agreed that human activities have been the biggest contributor to such change. Burning fuel in factories, cars and buses affects the earth’s natural greenhouse. The heat of the planet is trapped in the 4

atmosphere making the Earth warmer. This phenomenon is called the greenhouse effect. Both production and consumption of goods contribute to global warming. Production as in manufacturing utilizes technology that emits large amount of carbon in the atmosphere. Distribution of goods such as shipping and storage in warehouses and distribution centers also produces hydrofluorocarbons that contribute to the greenhouse effect. Consumption produces wastes especially non –biodegradable one that pollutes the atmosphere when disposed through burning which also releases carbons. The food consumption and production have a major impact on the surroundings. The means we have a tendency to consume has each direct and indirect impact on the surroundings. An example of this consumption is that the uses of energy in our homes like television radio, computer, cars and public utility jeepney that emit harmful gasses and caused pollution and increased emissions of greenhouse gases that results in global climate change. Consumption conjointly vie an indirect impact towards our surroundings from the assembly, process and transportation of the products that we have a tendency to consume daily. Examples of this production of goods we consume are the can goods, soft drinks, processed foods, shampoo and many more.. In association, with consumption and production pattern within the Philippines, the state of surroundings in our country along with the emissions of greenhouse gasses, indicators on pollution and also the generation of material discovered that each one indicators show environmental degradation all told the domains being assessed (Sta. Romana, 2017). Disadvantages A. Failing economy will have a domino effect on its trading partner in another counter. This is evident among the European Union in which bail-out was made to save an economically failing nation. B. Wealth and power are concentrated in the hands of small group of corporate elite putting smaller competitors in disadvantageous situation resulting to weakening of their business capability that usually ends up selling their business to bigger companies. 5

C. Introduction of international products and brand makes way for business domination of bigger and developed countries making the cultural exchange one-sided in favor of those who dominate the market. Six Ways Climate Change Will Affect PH Cities Pia Ranada January 22, 2014 Rappler.com El Niño, sea level rise, ocean acidification are just some scenarios PH cities face due to climate change. Manila, Philippines – Climate change is happening now and it is happening, not in far-flung corners of the world, but in human communities. Scientists say human activities are largely responsible for the continued increase in average global temperatures, which causes climate change. Global greenhouse gases emitted by the fossil fuel industry (which gives us electricity and fuels our cars) trap heat in the Earth’s atmosphere thus warming the entire planet. Philippine cities will likely to experience at least one of these effects of climate change: 1. More intense El Niño The El Niño phenomenon occurs when the surface of ocean waters on the southern Pacific becomes abnormally warm. The energy created by this warming is so great that it can create an imbalance in the weather in different parts of the world. In Southeast Asia, it can lead to abnormally dry conditions. El Niño can also make other weather events like storms highly unpredictable. Weather will have extreme highs and lows, making it “increasingly difficult to accurately predict weather patterns for purposes of planning and normal business operations,” says a WWF-Philippines study.

2. Sea surface temperatures to rise By the end of the century, sea surface temperatures are expected to rise by 1 to 4 degrees Celsius. This can lead to more powerful storms because storms get their strength from heat rising from the sea. 6

In the Philippines, 4 and 5 degrees Celsius spike above the normal sea surface temperature have been recorded. Warmer seas kill coral reefs and can thus lead to a decline in fish catch, putting food security in danger. 3. Ocean acidification The shift in the pH levels of our oceans can lead to widespread coral reef death. Because of the imbalance, shrimps are not able to develop skins, oyster cannot develop shells. Fish larvae may not be able to develop bones. This further endangers food security and the livelihood of fishermen. 4. Sea levels to rise by 4 to 6 meters Current data show an increase in sea surface heights. Scientists say this is due to the melting of ice sheets in northern portions of the globe like Antarctica and Greenland. Sea level rise by 4 to 6 meters can submerge low-lying communities like Tacloban City which stands 3 meters above sea level. 5. Tropical cyclones to intensify The creation of tropical cyclones is already being recorded in areas where the phenomenon had never been observed. On Nov. 8, 2013, Super Typhoon Yolanda (Haiyan), said to be the strongest storm in recorded history, devastated cities in the Visayas. 6. Rainfall, river flow, and flooding to intensify Monsoon rainfall in the Philippines will reach new highs and lows. Some parts of the country will experience an upward trend in rainfall while other parts will experience an intensification of drought. These two extreme poles of weather will make it more difficult for agriculture and aquaculture sectors which are highly dependent on weather. Philippine cities are already experiencing unprecedented amounts of rainfall. In Tacloban City, rainfall increased by 257% from 1998 to 2011. More rainfall will lead to more flooding and can trigger landslides in upland communities.

Discuss personal contributions that can actually solve the problem of climate change

Let Us Study Paskill (2018) suggested eight (8) simple ways to help care our environment. In every little thing you make a difference. 1. Use Reusable luggage If you're attending to mall for searching like grocery, food, and garments you would like to apply the plastic luggage. Mistreatment reusable luggage helps the atmosphere. Plastic grocery-type luggage that get thrown out find yourself in landfills and it takes years to decompose. 2. Print as very little as Necessary Using such a lot paper is damaging to the atmosphere. If possible recycle the utilization writing paper for printing. If not, print on either side of the page to scale back the number of paper used. 3. Recycle Instead of throwing recyclables within the trash along with your nonrecyclables, recycle the materials of fine use. create a degree to require an additional step to separate reclaimable materials like cans, bottles, plastic and papers. 4. Use a Reusable nutrient Containers In most school, fruit juices is served mistreatment plastic cups, rather than shopping for this cup of drinks on an individual basis, deliberate to use a reusable bottle. Not solely can this facilitate the atmosphere it saves your money for several of the campuses that provide water fountains designed for drinking still as for replacement reusable water bottles.

5. Don’t Throw Your Notes Away Keeping your notes can facilitate the scholars by having the ability to scan what they're learning within the words of another student. If you can’t notice anyone to convey the notes to, at the terribly least, recycle the paper you used. 6. Save Electricity! Use energy-efficient light-weight bulbs rather than regular bulbs. They last longer, which can save your money. Make you turn off lights, the TV, and other appliances when you are not using them. 7. Save Water Water is wasted a lot frequently than we can see. Shut down the faucet as you're brushing your teeth. Don’t turn your shower on till you’re able to get in and wash your hair. Limit your water usage as you wash dishes. 8. Avoid Taking Cars or Carpool as possible Cars square measure harmful to the atmosphere. Taking public transportation, walking, or riding a motorcycle are better options that help the environment and your budget, as well as getting some exercise. Madaan (2018) also suggested that t...
