Environment:
Science helps the environment because it creates an understanding between human impacts and the environment. By gaining this understanding of how the natural world works, the human race will better know how to protect it. In addition, scientific research is being used to reduce the impact of global warming, adapt to climate change, clean up polluted areas, and protect our own health.
Health:
Science can be used to improve global health because it fuels discovery, informs the public on health risks and programs, and helps all people live healthier and better lives. People with physical and mental health can benefit greatly from a variety of health sciences that specialize in their specific ailment. There have also been improvements in the technology used in health such as sanitation, vaccinations, and monitoring systems. By enabling doctors to do minimally invasive surgeries and using more comfortable scanning equipment, patients spend less time recuperating and can spend more time doing what they enjoy.
Peace:
It is my opinion that communication is the main way that science influences peace. Scientists from all over the world collaborate in an unbiased way to focus on one main goal, to deliver scientific breakthroughs to people regardless of religion, race and culture. Furthermore, science contributes to the social and economic development in a society (such as GDP, life expectancy, and literacy), reduction of poverty (through new was to meet basic needs for food, clothing, and shelter), and inspires a newfound peace mindset.
Equity:
Peace is a strong piece of science and, therefore, equity. Science is heavily rooted in the creation of new knowledge, the improvement of education, and the improvement of the quality of human life regardless of bias. Because of this, science can be used to research and find ways to solve pressing issues like racial and economic inequity. Learning of science in schools also has an impact on equity by teaching children the basis of our world and how to understand in order to gain skills that lead to better economic and social outcomes.
