A measure of the amount of light given off by a star is its absolute luminosity or magnitude. Absolute magnitude<span> is the measure of </span>intrinsic brightness<span> of a celestial object. It is the hypothetical </span>apparent magnitude<span> of an object at a standard </span>distance<span> of exactly 10 </span>parsecs<span> (32.6 </span>light years<span>) from the </span>observer<span>, assuming no </span>astronomical extinction<span> of starlight. </span>
Answer:
It's best to have most of the growth happen in developed countries. This for several reasons:
- Developed countries as a whole have less population, so a population increase in these countries represents less people in absolute numbers.
- Developed countries can invest in green energy more easily. For example, in Germany, 27 percent of energy comes from renewable sources, and in Norway, an oil-exporting country nonetheless, around 30% of cars are electric. They can do this because they are wealthier, and investing in renewable energy can be expensive.
- Developed countries are not likely to grow at high rates anyway. Developed countries are aging fast, their population pyramids are bulky in the middle, and every year, less women are available for giving birth. Developed countries will not grow at high rates in the coming decades unless the receive massive immigration.
