Viroids are small single stranded RNA molecules and are found in plants only. Hope this helps.
Renewable resources helped the human population in the last 100 years, by giving us a cleaner environment, and allowing us to harness the usage of energy generated from wind, solar, etc, to change it into electricity, which could help things move or give it power. For example, electricity can be used to charge the laptop or phone you are using, it can be used to power cars (Tesla), etc.
Something that is detrimental in the last 100 years, is the technology of missiles and nuclear power. Sure, nuclear power can help create power and the like, however, it can also be used to create weapons of mass destruction. It also pollutes our environment, which can lead to health problems. Finally nuclear energy is usually associated with Nuclear bombs, which would affect the environment, destroy human population and how they live, and damage the land for hundreds of years. Example of this includes Hiroshima and Nagasaki, which are still affected today from the 1945 atomic bombs. Some solutions to this is to get the affected things to outer space, and send them far away from earth. However, this is costly, and it could have a backlash if not done right. Another way is burying under the ground, however, this should not be used extensively, due to poisoning in the ground, and it would affect the people, animals, and plants.
using these two paragraphs, you can build up the rest of the essay. For the 4th paragraph, compare the two. For the first paragraph, introduce the problem. For the Last paragraph, give a summary, and give your opinion.
