A) a large fault on Earth's crust
Answer:
Hurdles in achievement of sustainable energy
Explanation:
One of the biggest hurdles in sustainability is that of the Human Behaviour, Poverty, migration and marginalization of poor, the example of changing customer requirements and rising the demand Second is climate change and global warming. Example of depletion of natural resources and increase of man led disasters. The conflict that arises from disputed related to natural resources availability. Such as the sharing of rivers at borders. Thirdly the crimes conducted against the environment like illegal deforestation and trade of species hence destruction of their natural environment.
Answer:
2 opposite forces
Explanation:
Conflict between two opposite forces idead or belief
for short
2 opposite forces
Anthropogenic changes are alterations that result from human action or presence. ... Increased production of carbon dioxide and other greenhouse gases and the resulting alteration of global climate is a good example of anthropogenic change that has been slowly revealed over the past several decades.
The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1
Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.
The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.
Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.
