The article discusses the impact of transportation to global climatic changes. Studies show that the transportation contributes 2.01 gigatonnes of carbon dioxide annually. In an effort to minimize or reduce carbon emissions, governments worldwide formulate different strategies. In Boulder Colorado, authorities have redesigned its service to make the buses smaller and more frequent thus increasing ridership five-fold. In Hasselt, Belgium, it made its buses free, paid for by city taxes thereby increasing ridership 10-fold.

The article discusses the impact of agricultural farm industry to global climatic changes. Studies reveal that the world's agricultural meat industry contributes 5.7 gigatonnes of carbon dioxide and 6.3 gigatonnes come from forest destruction. It reveals that animal agriculture releases the deadliest greenhouse gases, methane from cow's stomach and nitrous oxide from animal manure and use of nitrogen fertilizer. To solve the problem, mankind must learn to eat less meat and dairy, turning to the tastes, pleasures and health benefits of vegetarian food. Research shows that the destruction of the world's tropical rainforests releases 17 percent of the world's carbon emissions so they must do their share to protect the forests in the Amazon, Congo and Indonesia.

The article discusses the impact of electricity to climatic changes worldwide. Studies show that mankind's electricity production contributes 2.43 gigatonnes of carbon dioxide emissions annually. To reduce global warming, it is suggested that mankind's electricity sources should be derived from natural sources such as wind, sea, earth and sun. According to Trans-Meditteranean Renewable Energy Cooperation, a square kilometer of hot desert receives solar energy equivalent to 1.5 million barrels of oil, such great amount is several hundred times more energy needed by mankind. Energy can also be gathered from the wind as what North Dakota does wherein it has enough wind energy for 33% of the current demand of the country's electricity.

The article presents a set of questions related to environmentalism which may be used to check how environment friendly an institution is. The first question is whether the institute recycles its waste paper, cardboards, cans and glass. Another question is concerned with avoiding the use of most toxic garden and household pesticides, and using environment-friendly alternatives instead. One more question is to ensure that donations, pensions and other funds are invested in a socially and environmentally responsible manner.
