Starting any speech about climate change, I want to note down that it’s high time to talk. It’s time to do. Climate change is not any personal or family problem, it’s a universal problem. But still, we have a problem understanding this is a problem and those who really care for this universal problem most of the time they are neglecting by others. Prevention is better than cure but our planet is now really affected so we should start both.
Reforestation: Trees are the first weapon to fight against climate change. But Forests are facing intense competition from industry and agriculture. So we have to stop decrease forests and regrow the forest. Trees can absorb carbon dioxide and other gases. Trees not only absorb harmful gases but also make oxygen. A single mature tree can make enough clean air for 4 people and can absorb 48lbs carbon dioxide which is the main culprit in greenhouse effects. In fact, we could remove roughly two-thirds of human-made carbon just by letting all forests regrow, according to a study published in the journal of Science. Yep, two-thirds. Trees can protect coastal communities from severe flood and Strom. Trees shade is more preferable than the air conditioners which can prevent your electricity bill. Trees shade helps the soil retain moisture rather than drying out, and thereby supports fertile agriculture. For healthy ecosystems that convert the sun’s energy through photosynthesis, absorbs and transfers carbon, make soil, and provides a treasure trove of natural yet-to-be-discovered biological solutions for cleaning up our planet (for example, enzymes that can eat plastic). To prevent wildfire trees are the best way. So plant the tree as much as you can.
Building Weatherization: Weatherization describes the steps taken during building design or retrofit to increase energy efficiency by limiting unintended air and heat exchange between the indoor and outdoor environments. The energy we use to heat Vermont’s residential, commercial and industrial buildings accounts for more than 30% of our total energy use and costs more than half a billion dollars a year. If we button up our buildings and transition to new, efficient heating systems fueled by renewable energy, we’ll make Vermont living more affordable, and we’ll help fight climate change too. The dominant uses of energy in the residential sector are ambient space heating and cooling, water heating, and lighting. This section describes some of the means typically used to tighten buildings and the effect of tightening on ventilation. There are four common methods for reducing unplanned air leakage in buildings. Air-tighten the enclosure. Sealing cracks, gaps, and holes in the building envelope with vapor barriers, and other construction changes reduce the amount of air that accidentally leaks in or out. It’s a little step but necessary to replace old bulbs. LED bulbs can be used as indoor lighting or street lights which can really make a difference between saving energy and bills. Choose the most efficient lights and home appliances.
Waste disposal: Waste management has at least 5 types of impacts on climate change :
1) Landfill methane emissions
2) Reduction in industrial energy use and emissions due to recycling and waste reduction.
3) Energy recovery from waste.
4) Carbon sequestration in forests due to decreased demand for the virgin paper; and
5) Energy used in long-distance transport of waste.
Likely landfills and incineration emit greenhouse and toxic gases – including methane – that are released into the atmosphere, soil, and waterways, contributing to the increase of the greenhouse effect. Keeping carbon dioxide out of the atmosphere is a waste management problem. Carbon dioxide is a waste product, dumping it into the open air is a form of littering. Dumping can be avoided or cleaned up with technological fixes to our current infrastructure. Set targets for the recycling of construction and demolition debris and reuse of salvaged building materials. Compost food and landscaping Waste. Choose those manufacturer company which has the process of recycling or collecting their electronic product. We have to think about recycling and reuse technology and should be at a comfortable price.
Reducing fuels emissions: Burning fossil fuels are one of the main reason for climate change which is mostly occurred in transportation and industrial section. Cars are one of the biggest contributors to climate change: 82% of emissions from transportation come from cars. Emissions can be lowered by becoming energy efficient and by switching to low-carbon fuels. Reducing fuel emissions doesn’t mean that we have to compromise our comfort zone or sacrifice a big amount even this type of project can be a low cost and money saver also. Choose to walk not ride if you can’t walk then try to rideshare or public transport. Avoid aircraft if there was an option to go by train. When the time to buy any vehicle always chooses a climate-friendly option. Promise to yourself, your car engine will be stopped during traffic jams or signals. So it’s essential to progress towards an energy system based on fuels with low, or no-carbon, content (de-carbonization). This means moving away from using conventional coal and gas-fired power to electricity generated from nuclear power, renewable sources, and new technologies such as carbon capture and storage.
Renewable energy: Carbon dioxide is the climate’s worst enemy. It’s released when oil, coal, and other fossil fuels are burned for energy—the energy we use to power our homes, cars, and smartphones. Only renewable energy can migrate to this problem. Renewable energy is energy that is generated from natural processes that are continuously restocked. Water, wind, tides, solar, heat, various forms of biomass can be the source of substitute non-renewable energy. This energy cannot be exhausted and constantly renewed. Renewable energy can be played a great role in social and economic development. When the use of renewable energy increases, the demand for fossil fuels will decrease. Renewable facilities are also easy to maintain than a traditional generator and it produces little or no waste products such as carbon dioxide or other chemical pollutants. The IPCC ( Intergovernmental Panel on Climate Change) said that if governments were supportive, and the full range of renewable technologies was deployed, renewable energy could account for almost 80% of the world’s energy supply within four decades.
Education: When climate change is our global problem we share the same climate then public awareness should be spread all over the world. I feel climate change awareness should be a lesson of our academic study. The student will do the project, conversation, discussion, depreciation, the debate about climate change. Every separate step can be a power ultimately like driving habits, plant trees, waste management, avoid aircraft and red meat, etc. One person can provoke his family at least a partner. There is much organization are working to educate basically girls. Because they can make a lower carbon footprint by family planning. And also women have an inconsistent share of decision making around water, cooking, food waste, fuel choices, and how homes are heated, built, and used. Convince others and yourself to be a climate warrior. Remember we are the last generation who can change the course of climate change.
Finally, I tried to describe all possible ways to fight with changing the climate. But it’s not any individual work, we all need all.
