Currently,people around the world have been focusing on facing climate change. Climate change is the major global challenge today, and the world is becoming more vulnerable to this change. The recent report from the United Nations predicted that the average global temperature could increase by 6 ˚ Celsius at the end of the century . Increasing temperature causes warming oceans and lead to changing weather and rainfall patterns which threaten both urban and rural population.Climate change is best defined as the long term change in weather pattern which causes several events such as melting of polar ice, raising sea level, and increasing intensity of natural disaster .In my report,I decided to outline the main problems caused by climate change, and evaluate three possible strategies to address its negative impacts. The report argues that climate change has negative impacts on human life. However, its impact could significantly be reduced by implementing three strategies, including supporting green transportation, building green cities and implementing organic farming. There are various potential impacts of climate change on human life. Firstly, the rise of sea level as a result of increasing global temperature and unknown weather patterns. A report from the Union of Concerned Scientist points out that the average global sea level has increased by 8 inches since the last century. This increases the risk for low laying areas from flood and threatens coastal properties. At the moment 65% of major cities are located in low-laying coastal zones . Secondly, climate change may also affect energy demand. Another impact of climate change is the effect on human health. The report from Intergovernmental Panel on Climate Change (IPCC) points out that climate change affects human health due to decreasing quality of fresh air caused by air pollution and disruption of food supplies. These three impacts are the major impacts of climate change, and it would be worsened by the rapid growth of urbanisation and population. Without systematic and organised action, such effects from climate changes will become more difficult in the future. In order to address the effects of climate change, there are three strategies that can be done. 1. First of all by establishing green transportation. Transportation is the most important source of emission (UNDP 2012). Best known that transportation sectors are responsible for 30% gas emission and nearly 95% are from fossil fuel (EPA 2018b). Green transport is established by reducing the use of private cars and encouraging public transport. In addition, vehicles should be eco-friendly and encourage renewable energy. The government may impose a pool sharing policy to reduce the use of private cars which are bound to be successful. Moreover, the industry sector is also stimulated to develop green car technology which reduces fuel consumption and pollution. 2. Development of green cities. The city is the centre of the population nowadays. More than 50% of the world population lives in the city, and by 2050 urban dwellers are expected to reach 66% of the world population (FAO 2018). The UNDP reported that around two-thirds of global energy use is coming from urban areas. Cities are responsible for 67% of energy demand and major contributors of greenhouse gas emission. Building a greener city cannot only be done by developing and planting urban trees but also by implementing better urban planning. Urban planning means that city development and infrastructures such as transportation, sanitation, water management, housing and other cities facilities are well managed. Singapore is one of the successful cities on implementing green urban planning by reduction of vehicular emission, development green building and implementation energy efficiency. In addition to accomplishing the two previous strategies, this report proposes the application of organic farming. Agriculture sectors contribute around 24% of global emission, it mostly comes from the use of fertilizer in crop and livestock production . Organic farming means using non-chemical fertilizer and local input in its production process. Chemical fertilizer is commonly used in conventional farming, and it is the source of gas emission. Organic farming would produce healthier food and support food sovereignty since it encourages sustainability in agriculture production. To sum up, climate change has negative impacts on human life. There are many problems that are caused by climate change, including increasing sea level, rising demand on energy, and threatening human health. This report ends by arguing that three solutions including: supporting green transportation, building a greener city and implementing organic farming could significantly solve the climate crisis.

This is great, but more than organic farming is needed. Vegan farming will be totally necessary for food security and sustainability.
