Explanation:
Because if we're simultaneously moving/manipulating two different variables it can be very hard to determine why one variable is changing and why the other is changing. While this can be done with more complicated experimental designs, it usually is the case that scientists will only manipulate one variable and not two different ones.
Answer:
In my opinion, a reduction in our use of energy would not be a historical step backwards.
Explanation:
We already know that humanity's consumption of fossil fuels is wreaking havoc on the ecosystem. Fossil fuels pollute the environment where they are generated and utilized, and their continued usage harms the climate of the entire world. Nonetheless, altering our behaviors in a significant sense has proven to be quite difficult. As a result, it is not impossible to reduce our energy use significantly, but we may take little efforts to change the way we create energy, such as using fossil fuels. Because fossil fuels are so detrimental to our environment, we should try to reduce its use, but not at the risk of improving our surroundings. There are several methods to change the way we utilize energy now into something more sustainable.
