Answer:
a. replacing fossil fuels with nuclear energy
d. choosing a fuel-efficient car, or bicycling to school or work
e. using more electrical appliances and cars
Explanation:
The global warming is one of the biggest themes on global level, and there are lot of concerns about it, though all the relevant studies show that the concerns are way too exaggerated, still lot of problems can occur from it. The reason for the rise of the temperature globally is the increased level of carbon dioxide and methane into the atmosphere. In order to reduce the emission of these two gases, the humans can do certain things that would help both them, and the environment. The fossil fuels are the largest source of carbon dioxide, so replacing them gradually with nuclear energy, which is not emitting greenhouse gases, would be an excellent move. The use of the electrical energy in front of the energy from the fossil fuels will also do a lot of good, as the majority of the electrical energy is produced in a manner where it doesn't have carbon dioxide emissions. Healthy habits, like the bicycling, will both help the human health, make less of a traffic jam, is cheaper, and is not doing any emissions. Fuel efficient cars do help as well, as even though they have emissions of this gas, they are significantly lower, while the electric cars are very environment friendly, but unfortunately they are also very expensive so not a lot of people can afford them.
