Today, thanks to developments in scientific research and mass media, people around the world are more conscious of environmental concerns than ever before. However, despite some of the actions people are taking to address climate change (like non-binding global treaties and habitual household actions like recycling and composting), scientists are saying that it is not enough.
The term globalization refers to the increasing interconnectedness of countries around the world. A key part of globalization is increased international trade, which means more and more transportation vessels like planes and boats polluting the air. As a result, globalization has led to a profound increase in greenhouse gas emissions. These emissions trap heat and over time have led to climate change. This change is having a permanent impact on the Earth by altering weather patterns, food and water supplies, air quality, sea levels, and more. People and animals are not used to these changes and thus climate change is leading to a loss of biodiversity and threatening human health.
Population changes have also put a strain on the environment because the more people there are, the more goods must be produced to keep those people alive. As long as the population is this large, there will continue to be a need for large amounts of critical things like food and housing. The large global population is one of the reasons for harmful practices like industrial agriculture, an industry that is one of the most significant contributors to climate change since cattle emit lots of methane into the atmosphere.
The severity of these problems cannot be understated. However, there are lots of people around the world who know this and are taking some steps to address it. For example, recent movements promoting the benefits of locally grown food have the potential to help reduce the environmental harm caused by industrial agriculture. If alternative ways of producing and consuming like this become more widely adopted, there is a chance that the global community may effectively address many pressing environmental concerns, or at least buy some more time to prepare for and prevent imminent disasters.
