Unlike carbon-based fuels like coal, natural gas, and petroleum, nuclear energy does not release greenhouse gases into the atmosphere. Therefore it does not contribute to global warming.
Explanation:
Nonetheless, nuclear energy is not widely adopted for energy because of its safety concerns. Fission energy is harmful to the environment because of nuclear waste it generates. How this nuclear waste is stored is very important because leakage can lead to contamination of an environs with lethal radioactive elements.

Answer:
These crops where improved with technology, production of high-yielding variety, and improve farm practices. All these ensured the crops of green revolution had increase yield.
Explanation:
Through genetic engineering, high-yielding variety of cereals e.g wheat, maize, rice, were genetically engineered so that certain features which enhanced increased productivity were selected for.
Use of fertilization, the adoption of mechanization,good cropping and farming system are other factors which enhanced yield of these crops. Specifically, these crops were modified to enhance their Nitrogen uptake, which promotes rapid growths.
