Although a certain amount of carbon dioxide (CO2) occurs naturally in the Earth's atmosphere, there are several human activities that increase levels of the greenhouse gas. While some scientists are beginning to focus on rising atmospheric levels of nitrogen trifluoride, methane and soot, the produ...
Plants convert carbon dioxide back to oxygen, but the release of carbon dioxide from human activities is higher than the world's plants can process. The situation is made worse since many of the earth's forests are being removed, and plant life is being damaged by acid 当燃料被烧时,...
Life cycle assessment (LCA) and carbon footprints are largely used to attribute climate change impacts to specific human activities like products, technological systems, or sectors (Hellweg and Milà Canals i, 2014). Decision and policy makers widely rely on the outcomes from comparative climate impa...
It involves activities such as planning, designing, manufacturing, marketing and support, with the goal of maximizing value, efficiency and sustainability at each stage while considering environmental, economic and social impacts.

My only objective is to show that the CO2 released by human activities, combined with slow ocean absorption/neutralization and sea surface temperature variation, is broadly consistent with the measured historical trend in atmospheric CO2, including the effect of changing average SST on short term vari...
In theory, the amount of carbon released by human activities—such as burning fossil fuels and chopping down trees—and the amount of carbon taken up by oceans, soils and the atmosphere, should balance. However, the numbers do not quite add up and part of the budget is considering 'missing...
Topic: The human activities have negative effects on the plants and animal species. Some think it is too late to do anything about it while others suggest taking effective actions to solve it. Nowadays, environment issue is more and more serious. And the plants and animals are damaged by the...
Carbon dioxide generated by human activities is promoting photosynthesis (光合作用) and causing a beneficial greening of the Earth’s surface.由人类活动产生出的二氧化碳正在促进光合作用,使得地球表面绿化。故选B 【2】分析推断题。该划线句子所在句子后半句To home in on the effect of CO2, …monitored ...
One of the biggest environmental impacts of human activities is air quality. The transportation sector contributes heavily to air pollution because most forms of transportation, including cars, planes and ocean vessels, use fossil fuels. When burned, fossil fuels release carbon dioxide and other greenh...
