Reflection #4 Oct.9th
Through study, we know that only 10% of the earth is land, and this 10% of the land may not necessarily be suitable for people to live in. Although we only have these places, our population has always been high. As time goes by, the density of the population is increasing year by year. Rapid population growth has also brought a series of hazards, such as climate change and waste. Different people have different views on climate change. The pessimists claimed that population would soon outstrip food supply, leading to famine, disease, and social disorder. Some thinkers named neo-Malthusians predict that due to global warming, shortage of cultivated land, freshwater conflicts, reduced fish stocks, and the world’s poorest developing countries will exceed the population in the next 50 years. The optimists have faith in mankind’s ability to find innovations, such as solar and wind energy, that will increase Earth’s carrying capacity. Although I know that we should increase the new generation to ease the aging, more and more people have also brought many resource problems, such as kindergarten enrollment, lack of medical staff, and the employment problems faced, these are all disadvantages of the population.
I think it is because of the rapid increase in population that it led to climate change and waste. When people breathe, they will emit CO2, and a large number of people will discharge a large amount of CO2, which is one of the causes of climate change. With the rapid development of material life, people’s lives are more and more convenient, followed by widespread waste: like coffee cups, beverage bottles, various papers, and food discarded everywhere. Nowadays, more and more people and businesses are starting to like plastic bags, and there are still many products that are over-packaged. A plastic bag is a non-degradable material, and it takes a long time to degrade it, but the time to degrade it is far less than the time it takes to produce it. I know that plastic bags are very convenient and fast to use, but in order to solve environmental problems, I think we should cut off the production of plastics at the source, so people will use more environmentally friendly canvas bags; in the process, you can try to put plastic bags. Change to a paper bag because the paper is a recyclable item. I think that in order to avoid the waste of food, we can take a little less from the pot every time so that the things in the pot will not be polluted, it is easier to save.
But the above three issues are not too bad for the poor and war-torn countries, because they are still asking for poverty and peace, and there is still energy to manage those, so in order to solve the above problems, the first Steps to do to solve the problem of poverty and war.
