In 1969, the Cuyahoga River in America caught fire, leading to the implementation of various pollution control measures. This incident brought attention to the severe pollution problem in the river, which was heavily contaminated with industrial waste and sewage. The fire served as a catalyst for the environmental movement and led to the passage of the Clean Water Act in 1972, which aimed to regulate and reduce water pollution in the United States.

Explanation
Motor vehicles, such as cars and trucks, contribute to approximately 50% of our air pollution. This is because they emit pollutants such as nitrogen oxides, carbon monoxide, and particulate matter from their exhaust systems. These pollutants can have harmful effects on human health and the environment, including respiratory problems and the formation of smog. Implementing measures to reduce vehicle emissions, such as promoting electric vehicles and improving fuel efficiency, is crucial in reducing air pollution.

Explanation
The 'Magic Number' of climate change, 350, refers to the concentration of carbon dioxide emissions in the atmosphere, measured in parts per million. This number is significant because it is considered the safe upper limit to avoid catastrophic climate change. Keeping the concentration of carbon dioxide below 350 parts per million is crucial in order to mitigate the effects of global warming and maintain a stable climate.
