How might life be different today if humans had stepped into the fossil record sooner?

History

RSB [31]3 years ago
5 0

We can only theorize about how the life would be if the humans appeared earlier on the Earth, as we can not create a perfect and accurate picture of how would the things have been.

If the humans were developing in the same manner as we had, than we can say that the humans would have been much more advanced. The technology would have much better, probably missions to the other planets would have been regular. The population would probably be higher, with most of the population being concentrated in highly advanced megalopolises.

The environment though would probably be in a terrible condition, with enormous loss in biodiversity across the globe, decline in the forests, and much emptier (with life) oceans. On the other hand, there's every chance that with the more advanced technology multiple animals and plants would have been resurrected, even some extinct very long time ago.

dentify and describe two environmental challenges facing Africa. Which challenge do you think needs the most immediate attention
vfiekz [6]

Answer:

Deforestation, water pollution, coal mining, nuclear waste, over fishing and industrial agriculture are just a few environmental issues facing Africa, but in my opinion coal mining is the most pressing as it involves other problems like deforestation and water pollution.

Here are a few ways it harms the environment:

Miners clear areas of trees to prepare the land for mining.

Coal mining releases toxic materials into the soil and water.

Bad mining can start coal fires which can burn for decades – releasing “fly ash” and smoke filled with greenhouse gases and toxic chemicals.

It releases coal mine methane which is 20 times more powerful than carbon dioxide.

Strip mining accounts for 40% of the world’s coal mines and the practices destroys landscapes, forests and wildlife habitation. It usually requires mountain blasting and the removal of trees and plants in the mining area.

Coal mining increases the risk of loosening top soils into streams and waterways and the sediments pollute our water and can smother plant life downstream and even kill fish.

Coal has traces of sulfur and nitrogen. When burned, these are released into the atmosphere. While these chemicals are floating in the air, they can mix with water vapor and fall back to earth as Acid Rain.

Coal is made of carbon. When burned, the carbon combines with oxygen and forms carbon dioxide –one of the main contributors to global warming and air pollution.

Aside from carbon, the burning of coal releases sulfur dioxide, nitrogen oxides and mercury compounds into the air.

When rain falls on coal stored in piles outside, the water that comes from these piles will contain heavy metal such as arsenic and lead, which can seep into the land and nearby bodies of water – killing fish and plant life.

Coal dust can cause respiratory problems in humans.

In summary, coal mining has negative effects both in the long run an in the short run.

What changed in American foreign policy from Samoa to Hawaii?
g100num [7]

Answer:

The United States changed from Isolationism to Imperialism

Explanation:

Before the period of 1890 to 1914. The United States foreign policy was termed Isolationism due to the government's insistence to always appear neutral to any conflicting party. However, by the late 19th century to the early 20th century, The United States foreign policy changed from Isolationism to Imperialism.

This was evident in the US government takeover of Spanish colonies such as Guam, Puerto Rico, Philippines, and unclaimed territory in areas such as Hawaii, Samoa, and Wake Island. This enhances the foreign image of the United States as a world power.

Why did the Palestinian Liberation Organization set up bases in southern Lebanon?
kirza4 [7]
The base for Palestinian Liberation Organization were set up in the south because of the following major reasons.
None of the other Arab countries wanted them, they had been driven out of Syria and Kuwait, and while a large number lived in Jordan, they were considered as outsiders by the dominant Hashemites. However Lebanon accepted some of them, although many remained in refugee camps. 
Another reason was, Southern Lebanon was bordering Israel, (much of which had been part of Palestine until 1948; both Jews and Arabs had dispute over which group should own the land). The proximity of Southern Lebanon to the state of Israel enabled the Palestinian Liberation Organization to launch offensives, in an effort to defeat the Israelis and recapture land they believed to be theirs.
