Why is the environment more important than the economy?

Answers

We can’t live without an environment

The environment is more important than the economy because it provides us with clean air and water, healthy food, and preserved nature. These all components benefit human health and result in far more economic benefit than the economic cost.

What do you mean by Environment?

The environment may be characterized as the sum total of all sorts of living and non-living elements and their effects which consequently influence human life and other animals. There are basically two factors that contribute environment, i.e. biotic and abiotic factors.

Explain how phylogeny, classification, taxonomy, and binomial nomenclature are all related.

Answers

Taxonomy is the study of the classification of organisms. Taxonomists study the characteristics of organisms in order to classify them into the appropriate taxonomic groups, such as kingdom, phylum, class, etc.
Binomial nomenclature is a system of naming a species using two names, the genus and the species (and sometimes subspecies), which make up the scientific name of a species. Examples include Panthera tigris for the tiger, and Canis lupus for the gray wolf.
Phylogeny, or phylogenetics, is the study of the evolutionary development of organisms and relationships between them. Phylogeny is a useful tool for taxonomists.

B. Relative humidity is 100%, and it may rain.
C. Relative humidity is 0%, and it may rain.
D. Relative humidity is 100%, and there is no chance of rain.

Answers

Answer:

B

Explanation:

I hope this helps :) :)

As the dew point temperature equal to the air temperature this implies that the relative humidity is 100%, and it may rain. The correct option is B.

What is relative humidity?

Relative humidity (RH) is a percentage ratio of the amount of atmospheric moisture present to the amount that would be present if the air was saturated.

If the air is completely saturated at a specific level, the dewpoint temperature is the same as the actual air temperature, and the relative humidity is 100%.

There would be no clouds, precipitation, or fog if humidity did not exist. Humidity is simply the amount of water vapor in the air that is required to form rain. Furthermore, water vapor retains heat in the air.

Since the dew point temperature is equal to the air temperature, it may rain and the relative humidity is 100%.

Thus, the correct option is B.

What roles do society, politics, and economics play in science?

Discovering the roles and influence that society, politics, and economics have on science takes some practice. Sometimes these influences are not obvious but appear only after a solution to the problem has been tested over a period of time.

These articles describe conservation problems and solutions that were influenced by scientific, social, economic, or political issues. As you read each article, take note of the sections that represent these factors. You will use these articles in your assignment for this lesson.

2A) If people stop cutting down as many trees, there won’t be as many resources from that such as paper may be the cost will go up. Companies will be mad if people stop them from doing business, cutting down trees, and making money for example some experiences people had when they confronted companies went like this, "We had chief executives slamming the phone down on us. I even had people threaten to punch me." But there are a lot of good things happening such as a lot of materials are made that are FSC certified so you can have a clear conscience.

3A) If people are cutting down trees, then those companies aren’t getting money then they lose job opportunities without people there doing their jobs then no products like paper can be made. Also, if trees aren’t being cut down clearing space places like houses or malls can’t be built there. There are some solutions though like what FSC certified places do is after they cut down a tree they plant a new one in that exact spot.

4A) A lot of countries are becoming FSC certified such as Russia. Just a little bit ago Russia had a very little forest that was FSC certified now it's 260,000 sq. km—a quarter of its commercial forests. 40 percent—of the forest area of Europe and North America is certified by the FSC...
