I believe that climate change is real, and it is caused partly by emissions released from burning fossil fuels that are already causing devastating problems in Australia and around the world.
The atmosphere and ocean are already warming, the glacier and ice are melting causing an increase in sea levels, and the concentration of greenhouse gases is increasing. In addition, climate change have impact on clean air and water quality. The atmosphere is more polluted from fossil fuel compulsion leading to public health problems and infections especially respiratory diseases like asthma among children whose lungs are more sensitive to air pollution than adults.
Many people understand the seriousness of climate change and agree about the urgent need to act. More and more countries around the world are beginning to do their part, by moving energy system away from fossil fuels, toward clean and sustainable energy resources like the sun and wind.
Our society is already moving toward clean energy. Solar panels are popping up on rooftops everywhere and a full quarter of the world’s electricity today comes from clean, sustainable resources. Despite the leaders of the major industrialized nations agreed in the summer of 2015 to a long-term goal of phasing out fossil fuels entirely and moving to an economy powered entirely by clean energy sources like wind, solar, hydro, and geothermal. Our political parties keep arguing on the extent and duration of reduction of carbon emission.
We need to think big today and make an aggressive cut in our carbon pollution emissions and transition toward a cleaner energy system for electricity, and transportation.
Transportation sector is a major contributor to carbon pollution emissions after the electricity sector. Many people are interested in getting an electric car, but the concerns of cost and whether there will be access to a charging station prevent many people from being able to choose this low-carbon option. We therefore need to invest in electric vehicle charging stations, just as we built the highway system.
The best and healthier option is to encourage people to walk, cycle and use public transport which is the best way to take more cars off the road. Public transport can move more people in fewer vehicles, which is good for clean air and reducing carbon pollution emissions. However, we need to make road safer for cyclers and we need efficient and reliable public transport.
Unfortunately, our society are increasingly more reliant on cars. More vehicles are registered in all states in Australia every year, with 20.1 million registered vehicles in 2021. With 26.4% diesel vehicles up from 20.9% in 2016. However, electric vehicles are still small in number, less than 0.1% of the vehicles. In Tasmania, 516,451 motor vehicles were registered in 2021, 79% increase from 2010. Moreover, Tasmania has a higher number of vehicles per population and has older cars.
Fish, dolphins, whales, and sea vegetations and corals play an important role in removing carbon dioxide, generate oxygen and reduce water temperatures. Destroying our sea and ocean habitats contribute greatly to global warming. Plastic invades every corner of the world seas with large garbage patches floating in the middle of the oceans. There is urgent need to move away from using plastics, and massive scales of fishing to protect and maintain our sea world.
