What are some specific measures being taken by individual citizens or governments to decrease the human impacts on climate change ?
There are many actions being undertaken by governments and by individuals that are meant, in whole or in part, to reduce the extent to which human action will lead to climate change. Not all governments and not all people of the world are participating in these efforts.
On the governmental level, a variety of things are being done. One of the more extreme measures is the imposition of a carbon tax. It is hoped that charging taxes on carbon use will reduce that use, thus reducing human impact on the climate. Only a very few countries have gone this far. In the United States, a number of things have been done. The government has been trying to support alternative fuels. It has raised the fuel efficiency requirements on cars. It has essentially banned the use of incandescent light bulbs. All of these are aimed at reducing the use of fossil fuels.
Individuals are generally doing things to use less fossil fuel as well. They are buying more fuel efficient cars. Some people are trying to reduce the amount of driving that they do. Other people are trying to eat foods that have less of a “carbon footprint.” Some people are trying to lower their thermostats in the winter and raise them in the summer. Again, all of these actions are meant to reduce the use of fossil fuels, thereby reducing human impact on climate change.
