|1906||The Antiquities Act, which aims to preserve ancient Indian artifacts under a new rubric of protected "national monuments," is passed by Congress and signed by President Roosevelt.

|1962||Silent Spring by aquatic biologist Rachel Carson exposes the harm caused by insecticides such as DDT. The book leads to the development of safer insecticides and to a ban on the sale of DDT within the United States. More significantly, it heightens the awareness of ordinary people, who demand new legislation aimed at protecting the environment—a word that enters common parlance around this time.|

According to EPA statistics, only one third of the nation's waters are safe for fishing and swimming at the time that the act is passed. Three decades later, about two thirds are safe.
The Endangered Species Act is passed to protect wildlife. The act expands federal protections to plants and all invertebrates; bans the killing of all endangered species, as well as trade in endangered species and their products; and permits non-native species to be added to the U.S. endangered species list. Every year the names of 35 to 60 insects, plants, and animals are added to the list of species threatened with extinction. By April 2001 there are more than 1,800 threatened and endangered plant and animal species around the world. |

The treaty is aimed at reducing heat-trapping gases such as carbon dioxide around the world. The Kyoto Protocol is ratified by nations in Latin America, the South Pacific, the Caribbean, and the European Union.

|2014||The UN's Intergovernmental Panel on Climate Change (IPCC) released an alarming report in March 2014 that predicted dire environmental and economic consequences for the entire world if the world's leading economies do not start to reduce greenhouse gas emissions immediately. The repercussions of climate change include a rise in sea level, a shrinking of ice and snow cover, the melting of glaciers, food and water shortages, crop loss, destruction caused by coastal storms, and increased poverty. In addition, the report said drought caused by global warming could contribute to geopolitical conflicts over water and land. In fact, several scholars and experts blame some of the current political instability in the Middle East on drought.
The Supreme Court ruled 6–2 on April 29 that under the Clean Air Act, the EPA has the authority to regulate air pollution emitted from coal plants that crosses state lines. Smog from coal plants in 28 Midwest and Appalachia states blows toward the east and increases pollution in states that are downwind of the plants. "Some pollutants stay within upwind states’ borders, the wind carries others to downwind states, and some subset of that group drifts to states without air quality problems," Justice Ruth Bader Ginsburg wrote in the majority decision.
