(1). Podcasting information on climate change to the public We should podcast the fact on climate change on social media like twitter or Instagram. It is proved that a twit storm is effective in publicizing a hotly-debated topic. Traditional social medias including newspapers and televisions (if possible) are effective as well. Community is really important when we are trying to disclose facts and suggestions because most people tend to believe in their friends and relatives who they are familiar with instead of strangers. Studies have shown that for communities in the United States, the distribution of solar panels is usually clustered in a few specific locations, for instance. (2). Replace non-renewable energy to renewable energy. Fossil fuels produce a lot of greenhouse gases that worsen climate change. Abandoning coal and using more renewable energy such as solar, hydro and geothermal ...... Researchers say emissions must peak by 2025 and fall by 43 percent by 2030 to keep temperature increases below 1.5 degrees Celsius. The use of sustainable energy sources such as solar and wind power is the most effective way to achieve this transformation. The author of the report pointed out that the cost of using sustainable energy has dropped significantly, for example, compared to 2010, the cost has dropped by about 85% in 10 years. [19] (3). Eat healthy. Although we are not vegetarians, we recommend that people should eat healthy, both for their own health and the environment. Meat production emits a lot of greenhouse gases because animals like cow and sheep produce methane, a more powerful greenhouse gas than carbon dioxide. Chickens and fish are more environmentally friendly. It is also effective for you to influence other people if you eat in a healthy diet. (4). Reuse Reuse is much more effective and sustainable than recycling. Nowadays, only a few plastic bottles are recycled because it is difficult and not cost effective for cooperation to recycle but not purchase new plastic packages for their products. We should use non-disposable water bottles instead of plastic ones, for instance. It is same for the food wastes: Composting was proved to be an inefficient way to utilize food. It produces greenhouse gases and uses organic matter less efficiently. However, it would be much more efficient if we could recycle the leftovers and make them into dishes. At present, some organizations are collecting leftovers from supermarkets and restaurants to cook and sell them as dishes.
