Which of the following actions can help mitigate global warming effects?

Promoting renewable energy sources is a key strategy for mitigating the effects of global warming. Renewable energy sources, such as solar, wind, and hydroelectric power, generate electricity without emitting greenhouse gases that contribute to climate change. By shifting from fossil fuels, which release significant amounts of carbon dioxide and other pollutants, to cleaner alternatives, we can reduce our overall carbon footprint and limit the buildup of greenhouse gases in the atmosphere. This transition is essential for achieving long-term climate goals, reducing dependence on finite resources, and promoting sustainability.

In contrast, increasing fossil fuel use contributes directly to greenhouse gas emissions, while deforestation reduces the planet's capacity to absorb carbon dioxide, exacerbating global warming. Expanding urban development can often lead to increased emissions through higher energy consumption and increased vehicle traffic unless it is specifically designed with sustainable practices in mind. Hence, promoting renewable energy sources stands out as the most effective action for addressing global warming.
